COMPLETION OF THIS PAPER IS REQUIRED. SUGGESTED DUE DATE IS: ____________________ Name: _______________________________________________ Date: __________ Period: _________ 5 Chemical Reactions and Equations (CHEMACTIVITY: Synthesis and Decomposition Reactions) How do chemists describe, classify, and predict the products of chemical reactions? 2 – You Got It! 1 – Needs Some More Work! 0 - Incomplete 1. On your own…Read the short section on synthesis reactions on p. 267 and study the following information: REACTION DESCRIPTION: In these reactions, two different molecules or atoms combine to form a single substance. REACTION FORMAT: REACTION GUIDELINES: A + B → AB 1. 2. 3. 4. Direct combination of two elements will produce a binary compound. Metal oxides and carbon dioxide react to produce a metal carbonate (-CO3). Metal oxides and water react to produce a metal hydroxide (-OH). Nonmetal oxides and water react to produce an acid 2. In terms of reactants and products, describe how you would recognize a reaction as being a synthesis reaction: 3. Predict the products of the following synthesis reactions, then balance each equation: (HINT: You MUST write the correct formula for the product first!) Ag + O2 → BeO + CO2 → P2O5 + H2O → Al2O3 + H2O → K2O + H2O → SO3 + H2O → BaO + CO2 → Al + Cl2 → 4. On your own…Read the short section on decomposition reactions on p. 267 and study the following information: REACTION DESCRIPTION: During decomposition, one compound splits apart into two or more substances. These substances can be elements or simpler compounds. REACTION FORMAT: REACTION GUIDELINES: AB → A + B 1. 2. 3. 4. Binary compounds break down into their component elements Metal carbonates (-CO3) break down into a metal oxide and carbon dioxide. Metal hydroxides (-OH) break down into a metal oxide and water Acids break down into a nonmetal oxide and water 5. In terms of reactants and products, describe how you would recognize a reaction as being a decomposition reaction: 6. Predict the products of the following decomposition reactions, then balance each equation: (HINT: You MUST write the correct formulas for the two products first!) Ag2O → Cs2CO3 → CuCO3 → Al(OH)3 → Fe(OH)3 → H2SO4 → ZnCO3 → RaCl2 → 7. How would you describe the comparison between synthesis and decomposition: Essential Content and Skills: How do you correctly identify, balance and predict the product(s) of synthesis reactions? How do you correctly identify, balance and predict the product(s) of decomposition reactions?
