can you write the answer clearly to understand it thanks What are PMIo and PM2s stand for, which one is more dangerous and in what unit we measure them? Solution PM represents particulate matter, which act as a parameter to represent/ measure air pollution level. PM 10 means particulate matter of size equal to or less than 10micrometer and PM 2.5 means particulate matter of size less than or equal to 2.5micrometer. (1 micrometer = 1 x 10 -6 meter).Â Â PM 10 and PM 2.5 are mesured in parts per million (ppm). Owing to the very small size relative to PM 10 , the former can pass through the respiratory tract to the lungs and other part of the body rather easily than the latter and found to be more fatal. .

Can someone show me the steps and also two examples on how to find which compound among four or five of them has the highest percentage of ionic character Solution The % of ionic character depends on the electronegativity difference between the two element which have been joined to form the compound Generally ionic character is highest for compounds between alkaline metals (electronegativity very low) and halogen (high value of electronegativity) The electronegativity trends increases from left to right in a period and decreases the down Hence the most ionic compound will be CsF (Flourie has the highest electronegativity on pauling scale equal to 4) The bonds of same element have zero ionic character i.e. F2,Cl2 etc .

Can someone suggest a hypothetical situation or scenario to exemplify Kosslyn Image Theory? Solution Imagination is cricial step in psychological theory It is a arguable pont that the imaginary is not just the ole form of internal representation, as an imagecannot present an object or scene without some interpretative function that picks out the salient features. In this hypothesis we can assume the five properties of imaginery: 1. Depcits info about brightness contrast etc 2. As the distance from center increase the activation degree decreases 3. The image surfacuce resoultion is limited to some context 4. The image is somewhat eliptical in shape 5. Images are more difficult to maintainm and store .

Can someone explain the more dilute the solution is (acid solution) the greater the degree of ionization? Can someone explain the more dilute the solution is (acid solution) the greater the degree of ionization? Solution Degree of Ionisation means no. Of ions increase. And degree of Ionisation is directly proportional to the degree of disassociation more will be the dissociation of solution more will be its no. Of ions . On dilution the degree of disassociation increase because water provides energy for dissociation of acid and thus degree of ionisation increase with dilution . .

can multilayers point to the same feature class Solution No , multiple layers cannot point to the same feature class, when you are publishing a map service with WFS capabilities it is not true. WFS service : If we use the WFS service to support transactions for editing (WFS-T), the source data for all the layers in the map must come from the same enterprise geodatabase; otherwise, the map cannot contain layers from multiple sources. Let us consider two or more layers in the map cannot reference the same feature class or have the same name. If they do, you will receive the error Workspace item or name is a duplicate . The name of the layer is the type name returned from WFS. .

Calculate the pH of the resulting solution if 22.0 mL of 0.220 M HCl(aq) is added to (a) 32.0 mL of 0.220 M NaOH(aq). (b) 12.0 mL of 0.320 M NaOH(aq). Solution number of moles of HCl = 22*0.22 = 0.00484 mol number of moles of NaOH = 32*0.22 = 0.00704 mol number of moles excess = 0.00704 - 0.00484 = 0.0022 pOH = -log([OH-]) pOH = -log(0.0022*1000/(22+32)) pOH = 1.39 pH = 14 - 1.39 = 12.61 number of moles of NaOH = 12*0.32 = 0.00384 mol number of moles excess = 0.00484 - 0.00384 = 0.001 mol pH = -log([H+]) pH = -log(0.001*1000/(12+22)) pH = 1.531 .

Calculate the radius of a palladium atom, given that Pd has an FCC crystal structure, a density of 12.0 g/cm 3 , and an atomic weight of 106.4 g/mol. Solution Lets assume the radius to be r. In FCC, a*sqrt(2) = 4r Thus, a = 2sqrt(2)*r Volume of cell = a^3 = 16sqrt(2)r^3 = 22.627*r^3 Number of atoms in 1 cell = 4 mass of one cell = 4 * 106.4 / (6.02 * 10^23) = 7.069 * 10^-22 g Now, mass = vol * density Thus, 7.069 * 10^-22 = 22.627*r^3 * 12 r^3 = (7.069 * 10^-22) / (22.627 * 12) = 2.603 * 10^-24 cm^3 Thus, r = 1.37 * 10^-8 cm .
