Unformatted text preview: C HAPTER 4 Quantities of Reactants and Products 63 Objectives You will be able to do the following. 1. Write a description of the information given by a chemical equation. 2. Write or identify the symbols used in chemical equations to describe solid, liquid, gas and aqueous. 3. Balance chemical equations. 4. Given a balanced chemical equation (or enough information to get one), convert from mass of one reactant or product to mass of any other reactant or product. 5. Write an explanation for why an excess of one or more of the reactants are added in a chemical reaction and explain why other reactants are limiting. 6. Given the mass of two or more reactants, calculate the maximum mass of product that could form from the reaction between them. 7. Explain why the actual yield in a chemical reaction is less than the theoretical yield. 8. Given an actual yield and a theoretical yield (or enough information to calculate a theoretical yield) for a chemical reaction, calculate the percent yield for the reaction. 8. Given a chemical equation for a reaction (or enough information to write one) and a value that describes the percentage of one of the reactants or products in a mixture, convert between mass of the mixture and mass of any one of the reactants or products in the reaction. 10. Write or identify descriptions of combination, decomposition, combustion, displacement (or single displacement), and exchange (or double displacement) reactions. 11. Write chemical equations for combustion reactions of compounds that contain carbon, hydrogen, sulfur, and/or oxygen. 12. Given a chemical equation, identify it as representing a combination, decomposition, combustion, displacement (or single displacement), and exchange (or double displacement) reaction. 13. Convert between the deFnition and the term for the following words or phrases. Skip section 4.7 of the text. 64 Chapter 4 Quantities of Reactants and Products Chapter 4 Glossary Chemical reaction or chemical change Te conversion of one or more pure substances into one or more diFerent pure substances. Reactants Te substances that change in a chemical reaction. Teir formulas are on the left side of the arrow in a chemical equation. Products Te substances that form in a chemical reaction. Teir formulas are on the right side of the arrow in a chemical equation. Coecients Te numbers in front of chemical formulas in a balanced chemical equation. Equation stoichiometry Calculations that make use of the quantitative relationships between the substances in a chemical reaction to convert the amount of one substance in the chemical reaction to the amount of a diFerent substance in the reaction. Limiting reactant Te reactant that runs out rst and limits the amount of product that can form....
