Subject Content = Covered. We are working on applications. Multistep and practical problems. 3 Dimensional problems. Setting out the steps in a logical and clear manner, which may include drawing triangles. . Datang. 欢. 迎. Vaazhga. Welcome. Professor David Wray. University of Warwick,. United Kingdom. Dr Dahlia . Janan. Universiti. . Pendidikan. Sultan . Idris. , Malaysia. Many thanks for coming to today’s meeting. Objectives. To learn how to write formulae for compounds. Outcome: you should be able to write the formulae for inorganic covalent compounds and ionic compounds comprising single atom ions or polyatomic ions.. 1. There will be 3-4 members in each group.. 2. Each person will measure one (1) substance in preparation for the lab. . Using a . digital balance. , measure the following substances: . 10 grams (g) . equations and formulae. Equations and formulae are used in Physics, Chemistry and Biology. Sometimes you will need to rearrange them to work something out.. To rearrange them, you need to understand what they mean.. Objectives. To learn how to work out the percentage composition by weight of a compound. To use percentage composition to work out empirical formulae. Percentage compositions. This means what percentage of each element is present in a compound, and therefore tells you what masses of each element are present in any given mass of a compound. . Can you place the numbers 1-8, one in each box, so that no two consecutive numbers touch?. Rearranging Formulae and Simultaneous Equations 8-11-16 . For the formula . The Mole. REVISION. Formulae tell you how many of each atom are in a molecule.. Different atoms have different masses.. Level 4. NEW LEARNING. Formulae and balanced equations. Formula Mass and the mole. .. The names and addresses of the associated institutions go here.. Course # - Course Name - Instructor. Introduction. Course Concepts/ Service Learning Activities. Community Partner. Reflection.
