Modules 1 a nd 2 i nvolve the study of the Earth's physical features and past life history. Modules 3 a nd 4 i nvolve the study of life and its interaction with the Earth. Modules 5 a nd 6 i nvolve the study of solutions as well as how chemistry is used for everyday things. Modules 7 a nd 8 i nvestigate motion, both on Earth and in space. The module you are working on is highlighted in a d arker colour. 1 Table of Contents ^ Module Overview 1 Evaluation 2 Section 1 : Chemicals in Solutions 3 Activity 1: Everyday Solutions 4 Activity 2: Dissolving and Qualitative Analysis 8 Activity 3: Classes of Solutions 17 Follow-up Activities 31 Extra Help 31 Enrichment 33 Conclusion 34 Assignment 34 Section 2: Concentration - T here's Exactly How Much? 35 Activity 1 : Consumers and Scientists 36 Activity 2: Preparing Solutions 46 Activity 3: How Much Is T oo Much? 53 Follow-up Activities 64 Extra Help 64 Enrichment 65 Conclusion 67 Assignment 67 Section 3: Stoichiometry - U sing Chemical Equations 68 Activity 1 : Balancing Chemical Equations 69 Activity 2: Stoichiometry 73 Follow-up Activities 81 Extra Help 81 Enrichment 84 Conclusion 85 Assignment 85 Module Summary 85 Appendix 86 Glossary 87 Suggested Answers 88 Digitized by the Internet Archive in 2017 with funding from University of Alberta Libraries https://archive.org/details/science2005albe Science 20 Module 5 MODULE OVERVIEW Do you remember those hot, dry summer days when you went to the refrigerator for something cool to quench your thirst? You accidentally tip over a b ottle of pop as you are reaching for it way in the back of the refrigerator; then you take it out to pour yourself a l arge glass. When you open the bottle, what do you see happening to the pop? It bubbles, foams, and makes it difficult to fill y our glass. The escaping gas is one of the reasons why you drink pop. The carbon dioxide gives the tingle in your mouth when you drink it. If all the gas escapes, then the pop loses some of its tingle. The pop you drink is not one substance but a m ixture of substances known as a solution. In this module you will study solutions and learn to describe solutions based on their contents and how they react. You will also learn to predict how much of a solution will react with another solution, or how much of a chemical can be produced when different solutions react. Module 5 Solution Chemistry Section 3: Stoichiometry - \j L ousing Chemical Equations 1 Science 20 Module 5 Evaluation Your mark in this module will be determined by your work in the Assignment Booklet.
