Percent composition is a calculation that determines the percentage by mass of each element in a compound. It is calculated by taking the mass of one element, dividing it by the total mass of the compound, and multiplying by 100. For example, water (H2O) has a percent composition of 89.9% oxygen because oxygen has a mass of 16.0 grams in water's total mass of 18.0 grams. Percent composition provides information about the elemental makeup of compounds.

Chemistry, percent composition is one of the topic under SHS that deals with the different compound found in our day to day food consumption. It is also said that most of the product that we consume everyday has different ingredients which is the combination of different substance, such elements, preservatives and others. For you to become well knowledgeable this slide presentation is presented for you to become easy for learners and for you. Elements and compounds that are present in our foods will be more convenient for us to know if we learn how much is the consumption do we need to intake.

SITE 2014 Presentation. Abstract: Blended learning in K-12 classrooms is growing at an enormous rate. While the Educational Success Prediction Instrument (ESPRI) has been used to predict the success of students in online courses, it has yet to be applied to blended courses. This study examined the use of the ESPRI to predict the success of students enrolled in a secondary advanced biology course where the first half of the course was offered in a traditional format and the second half was offered in a blended format. Differences in student performance between the two portions of the course were not statistically significant (p = .35). The ESPRI correctly predicted approximately 88% of the outcomes. Limitations of the study included a small sample size (N = 43) relative to the number of items in the instrument. Additional research should examine the effectiveness of the instrument on students from across the achievement spectrum and not what is considered the ideal online learner.

Dubai, often portrayed as a shimmering oasis in the desert, faces its own set of challenges, including the occasional threat of flooding. Despite its reputation for opulence and modernity, the emirate is not immune to the forces of nature. In recent years, Dubai has experienced sporadic but significant floods, testing the resilience of its infrastructure and communities. Among the critical lifelines in this bustling metropolis is the Dubai International Airport, a bustling hub that connects the city to the world. This article explores the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.

When you’re building (micro)services, you have lots of framework options. Spring Boot is no doubt a popular choice. But there’s more! Take Quarkus, a framework that’s considered the rising star for Kubernetes-native Java. It always depends on what's best for your situation, but how to choose the best solution if you're comparing 2 frameworks? Both Spring Boot and Quarkus have their positives and negatives. Let us compare the two by live coding a couple of common use cases in Spring Boot and Quarkus. After this talk, you’ll be ready to get started with Quarkus yourself, and know when to select Quarkus or Spring Boot.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.
