Intro! Chemical Reactions

Chemical Reactions Unit 2

What will be covered? In this unit you will be: Looking at Chemicals in Action Understanding Chemical Reactions Controlling Chemical Reactions Looking at Acids and Bases

Chemicals in Action- Chpt.5 Review of Matter: Pure Substances vs. Mixtures Looking at compounds ionic or molecular Chemical formulas and naming systems Recognizing chemical formulas, composition, and names

So what will you be doing? Review from Grade 9- Properties of Matter Periodic Table Bohr Models/ Lewis Dot Diagrams How elements form compounds Differences between compounds which are ionic and molecular

Understanding Chemical Reactions Chpt. 6 Classifying the reaction by the types of reactants Representing reactions using both word and balanced chemical equations Law of Conservation of Mass Looking at the products of reactions Useful or toxic ?

So what will you be doing ? Looking at word reactions and how to put them together. How mass in conserved through chemical reactions- how to show this. Balancing these equations Looking at the different types of reactions Synthesis vs. Decomposition Single vs. Double Displacement

Controlling Chemical Reactions Chpt. 7. What affects the speed of chemical reactions ? Ex: Temperature and Concentration of reactants Sometimes we need reactions to work more or less quickly. Catalysts and Enzymes Identify every day examples of ways in which rates of reaction are controlled.

Acids and Bases Chpt. 8 Acids and bases Importance Properties Ph scale and how it relates to the acidity of a solution Battery acid to drain cleaner and everything in between Ph and its affect on soil Explain the occurrence of Acid Rain through the knowledge of acids and bases.
