How do you think the DATA Act will impact governmental entities and stakeholders? I\'m not looking for political arguments. Solution By replacing inaccessible documents with standardized, searchable data--freely accessible to all--the DATA Act will create better accountability for taxpayers and citizens; improve federal management by illuminating waste and fraud; and reduce compliance costs by automating the creation of reports by grantees and contractors. Better accountability . Once federal financial statements, budget actions, grant reports, and contract reports are available as open data, rather than trapped in inaccessible documents, tech companies will be able to make the data fully searchable for citizens, taxpayers, and companies More effective federal management . Government-wide data standards for spending will allow Big Data analytics to illuminate waste and fraud. Coaltion members showed how at the DATA Demo Day on Capitol Hill in May 2013. Automated compliance . When federal agencies begin collecting grant and contract reports as standardized data instead of as documents, solutions like Parrascope and AmpliFund will help grantees and contractors comply with existing reporting requirements more cheaply than they can today. .

How do I determine the Rf Value with just the information I have provided? As for the Ion, are they looking for a poistive or negative answer? Rf= distance traveled by component/distance traveled by the solvent I just took a piece out of my homework so I can complete the rest Hopefully I will learn and then know what I am doing. Results Data Table for Unknown A Distance Solvent Traveled (cm) 7.0 Spot Color Distance Traveled (cm) 1.3 *Rf Calculated lon Present Unknown A Component 1 Unknown A Component 2 Brown with light spots Brown with light spots 4.6 4.9 Unknown A Component 3 Brown with light spots Solution For unknown A component 1: R f = (1.3 cm) / (7.0 cm) = 0.186 or 0.19 For unknown A component 2: R f = (4.6 cm) / (7.0 cm) = 0.657 or 0.66 For unknown A component 3: R f = (4.9 cm) / (7.0 cm) = 0.7 For the \'ion present\' column, it is being asked what ion is present in the unknown A which is determined by referencing to the R f values of the known compound and it\'s components. For example, first you are given a known compound having a ion (say given compound is NaCl which we know it contains Na + ions). Now paper chromatography for NaCl is done and R f values are calculated & noted for Na + ion. Now in second experiment you are given an unknown compound and you perform the paper chromatography and calculate the R f values. If R f value of Na + (from first experiment of known) matches with the R f value of unknown (from second experiment) then we can say that unknown compound contains Na + . This Na + is the ion which is being asked as \'ion present\'. .

How does SO 2 in the atmosphere affect global warming?Â Â Â In general, what are the consequences of SO 2 in the atmosphere? (This should be current (no older than 5 yrs. old) since our understanding has improved in the last 5 yrs. or so. In discussing general consequences, please make sure to include acid rain and an explanation of what it is.) Solution Sulfur dioxide (SO 2 ) is a colourless gas with a sharp, irritating odour. It is produced by burning fossil fuels and by the smelting of mineral ores that contain sulfur. However, SO2 oxidizes to H2SO4, which gets involved with aqueous chemistry and often leads to sulfate (SO4). Sulfate is an aerosol that will reflect sunlight (like many aerosols) and block energy input to the Earth. If you increase the amount of sunlight being reflected back to space (reducing the amount of sunlight absorbed by the surface of the Earth), there is a net cooling affect. Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by the wind. As a result, the two compounds can travel long distances where they become part of the rain, sleet, snow, and fog that we experience on certain days. .

How does an awareness of the historical link between the United States and China help explain the current relationship between the two countries? (Please do not copy/paste irrelevant information, I will report it) Solution Answer The us and china historical link helped in many ways like laws in both countries passed after taking into consideration the effectiveness of laws in one another country. The foundation of US and China relationship is based on Trade, Faith and Freedom which can be demonstrated with help of below examples: 1 . Americans have been interested in China for a long time. In 1784, when the American War for Independence was barely over, the first ship to sail under an American flag left New York. It was the merchant ship Empress of China , bound for Canton (now Guangdong), China. At first, the American interest in China was economic. Americans were looking for new markets to buy goods, as the British refused to deal with Americans. And the Chinese preferred to work with Americans, who bought Chinese goods. The Europeans only wanted to sell them things. By the middle of the 19th century, though, the relationship had grown. American churches led the way, seeking converts to Christianity among China .

How do you utilize PM software to manage team activities? Solution Project Management is the process and activity of planning, organizing, motivating, and controlling resources, procedures and protocols to achieve specific goals in scientific or daily problems. A project is a temporary endeavor designed to produce a unique product, service or result with a defined beginning and end (usually time-constrained, and often constrained by funding or deliverables),undertaken to meet unique goals and objectives typically to bring about beneficial change or added value. The temporary nature of projects stands in contrast with business as usual (or operations), [4] which are repetitive, permanent, or semi-permanent functional activities to produce products or services. In practice, the management of these two systems is often quite different, and as such requires the development of distinct technical skills and management strategies. The primary challenge of project management is to achieve all of the project goalsand objectives while honoring the preconceived constraints. The primary constraints are scope, time, quality and budget. The secondary .

how do the different architectures of a polymer affect their properties? Solution Polymers are affected by molecular weight and crystallinity. Linear polymers - single chains, flexible , van der Waals between molecules. Branched polymers - side branches , packing is less efficient, lower density,less crystalline than linear. Branching also affects chain entanglement, the ability of chains to slide past one another, in turn affecting the bulk physical properties. Long chain branches may increase polymer strength, toughness, and the glass transition temperature (T g ) due to an increase in the number of entanglements per chain. From an adsorption point-of-view, the bottle-brush homopolymers have the ability to attach to the surface through both side chain and backbone segments. If adsorption occurs through the attachment of the side chains on the surface, then the polymer attains a flat conformation at the interface since the gain in adsorption energy increases with the number of contact points between the side chain segments and the surface Dendrimers are a special case of branched polymer where every monomer unit is also a branch point. This tends to reduce intermolecular chain entanglement and crystallization. A related architecture, the dendritic polymer, are not perfectly branched but share similar properties to dendrimers due to their high degree of branching. .

How do phospholipid bilayers maintain specific concentrations of solutes inside and outside the cell? a. The interior of the bilayer is packed too tightly for any molecule to pass through b. The interior of the bilayer is too hydrophobic for charged or polar groups to pass The interior of the bilayer is solid-like preventing anything from passing through The exterior of the bilayer is too charged for any solute to get close The exterior of the bilayer is too hydrophobic for any charged or polar group to get close c. d. e. Solution The phospholipids in the plasma membranes are arranged in two layers, called a phospholipid bilayer. Each phospholipid molecule has a head and two tails. The head is hydrophilic, that is, it loves water and points outward. The tails are hydrophobic and these water hating tails are on the interior of the membrane. Molecules that are hydrophobic can easily pass through the plasma membrane because they are water hating like the interior of the cell. Charged or polar groups acts as hydrophilic substances so they do not pass through the plasma membrane because they are water loving like the exterior of the membrane. So they are excluded from the interior of the membrane. So option (b) is correct . .

how would a police department exhibit different structure and procedures under the crime control model than it would under the due process model? Solution Two models of crime: the due process model and the crime control model posses their own advantages and disadvantages Due process model provides an each and every people have equal rights and they cannot be underprivileged of life, liberty, or property without proper legal procedures. When people are arrested due to a crime then also they have their own rights such that they does not harm anyone and it is facilitated by Due process model. There are various dissimilarities in-between the due process model and the crime control model: The due process model thinks that people who are arrested by means of any event there ma be a chance that particular person doesnot do it anything and somebody involve him in this case. So he will be protected until it was proven and statement should be given by the court. Where as the Crime Control Model Process states tha the person who was arrested is right person who has done all those crimes so that particular person must be punished accordingly with respect to the safty of the remaining public. Crime control system believes that if it had done by maintaining the Due process it will take long l But the due process has equal rights to all the people because in some situations the people who did not do the crime also has a chance that somebody involve them into this crime. So we have to give chance to prove themselves that they are not accused so generally the court fallowes the due process model that says that every one are equal before the law. .

How will you close your knowledge gap, Is your mind geared to re-think what you think you know? Solution The knowledge gap theory was first proposed by Tichenor, Donohue and Olien at the University of Minnesota in the 70s. They believe that the increase of information in society is not evenly acquired by every member of society: people with higher socioeconomic status tend to have better ability to acquire information (Weng, S.C. 2000). This leads to a division of two groups: a group of better-educated people who know more about most things, and those with low education who know less. Lower socio-economic status (SES) people, defined partly by educational level, have little or no knowledge about public affairs issues, are disconnected from news events and important new discoveries, and usually arenâ€™t concerned about their lack of knowledge. Core Assumptions and Statements The knowledge gap can result in an increased gap between people of lower and higher socioeconomic status. The attempt to improve peopleâ€™s life with information via the mass media might not always work the way this is planned. Mass media might have the effect of increasing the difference gap between members of social classes. .

HOW they got -1.78 ????????????????? Assignment Brief Day 1: They\'ve left me\' Melanie, gasps to herself as she lies prone in the rust. Whilst out collecting rock samples with her colleagues a sudden Martian storm blew over the landing ground. Melanie was struck by a piece of flying debris and rendered unconscious without any means of communicating with her colleagues. Her c????? es were forced to leave the planet, believing Melanie to have perished. This is just like that bloody film starring Matt Damon\', Melanie thought to herself as she sat upright. Well I may as well get to growing potatoes in my own waste and producing water from left over jet fuel...\' Melanie resolved to forget the whole unpleasant experience of being left for dead on Mars whilst she ran combustion calculations in the hope of generating drinking water. Hydrazine (N2H4) is a fuel that undergoes chemical reactions to split into nitrogen gas (N2) and hydrogen gas (H2) through several processes. The liberated Hydrogen gas may then be reacted with oxygen to produce water. Melanie creates a device to receive a mixture with molar analysis 3/11 N2 and 8/11 H2 at 298 [K] and i atmosphere. This combination is then mixed with x (110-150) %] theoretical air from the habitat. The relevant thermodynamic properties are found from Melanie\'s computer, she assumes a constant heat capacity for all species (Table 1): Solution Solution: There is error in that equation it is not 1.78 but it is 1.68 as shown below, 1.91 - 0.273(100%/120%) = 1.6825 = 1.68 so change it to 1.68 .

how does molecular mass affect physical properties of compounds (solubility, boiling point, melting point, etc). Use CO2 and h2o as the compound examples. seriously, please provide a link to information as well, I can\'t find it anywhere Solution Solubility: - as the molecular weight increses the silubility decreses because the larger the molecules of solute are the larger is thier molecular weight and their size.. It is more difficult to the solvent milecules to surround around the bigger solute.. As co2 is higher molecular wieght than the water but being co2 a gas in nature. solubility of gases directly depends on the pressure.. But in h20 thier is hydrogen bonding and due to this it more soluble. Boiling point :- as the molecular weight increses the boiling point increses due to increase in vander wall force of attraction But as we compare the molecules co2 and h20 then the co2 has higher moleculer weight but lower boiling point than h2O because H2O molecules form hydrogen bonding and form large chain this lead to increase in thier boiling point Metling point :- as molecular wieght increses the metling point also increases but melting point also depned on type of bond i.e ionic or covalent or coordinate bond here both molecules are covalent but CO2 having higher molecular have low melting point because of thier state i.e gaseous state while H2O is liquid .

How do we know the CO2 in the atmosphere is of anthropogenic origin? How do we know the CO2 in the atmosphere is of anthropogenic origin? Solution The co2 present in the atmosphere is obtained through the natural process like biogeochemical cycle such as carbon cycle.. Carbon cycle is nothing but the exchange of carbon between the oceans,rocks etc., and biosphere which includes plants and animals...plants absorb co2 present in atmosphere and undergo photosynthesis process to prepare carbohydrates. Whereas these prepared carbohydrates are taken as food by the animals and human beings and these complex carbohydrates are converted into simple carbon compound nothing but co2 during respiration and while doing respiration releases energy into body inthe form of ATP and co2 into atmosphere.. According to carbon cycle the maximum amount of co2 present in atmosphere is anthropogenic origin. The interesting thing is that recent days the atmospheric co2 level is significantly increasing because of human activities like burning of fossil fuels,increase in population,decrease in oxygen level in atmosphere etc., .

How the addition of CaCl2 affects the molar solubility of the compound Ca(OH)2? Explain and justify How the addition of CaCl2 affects the molar solubility of the compound Ca(OH)2? Explain and justify Solution Calcium hydroxide (Ca(OH)2) is a sparingly soluble salt. The salt which is dissolved in the water is normally ionized as follows. Ca(OH)2 <---------------> Ca+2 + 2OH- This is equilibrium ionization process and can be affected by several factors. According to le chateliers principle if you increase the concentration of either Ca+2 or OH- ions in the solution, the equilibrium shifts towards backward direction and thereby the solubility of Ca(OH)2 would be decreased. ISo, by the addition of CaCl2 which is normally ionize as follows CaCl2 <--------> Ca+2 + 2Cl-, would increase the concentration of Ca+2 ions in the solution. So, the number of Ca+2 ions is increased in the solution and the equilibrium is shifted towards backside due to the formation of Ca(OH)2. So the equilibrium constant for the Ca(OH)2 in the absence of CaCl2 > in the presence of CaCl2 So the molar solubility of Ca(OH)2 would be decreased by the addition of CaCl2 salt. .

how many people are on this planet earth? Solution Earth, also known as the world, Terra, or Gaia, is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System\'s four terrestrial planets, and the only celestial body known to accommodate life. It is home to about 8.74 million species. There are over 7.2 billion humans who depend upon its biosphere and minerals. The Earth\'s human population is divided among about two hundred independent states that interact through diplomacy, conflict, travel, trade, and media. According to evidence from sources such as radiometric dating, Earth was formed around four and a half billion years ago. Within its first billion years, life appeared in its oceans and began to affect its atmosphere and surface, promoting the proliferation of aerobic as well as anaerobic organisms and causing the formation of the atmosphere\'s ozone layer. This layer and Earth\'s magnetic field block the most life-threatening parts of the Sun\'s radiation, so life was able to flourish on land as well as in water. Since then, Earth\'s position in the Solar System, its physical properties and its geological history have allowed life to persist .
