1. Sodium metal burns in air to produce sodium oxide. Write a balanced equation to represent this reaction. How many moles of oxygen are needed to completely react with \( 9.5 \) g of sodium? How many grams of sodium are needed to produce \( 12.5 \mathrm{~g} \) of sodium oxide? 2. Acetylene gas, \( \mathrm{C}_{2} \mathrm{H}_{2} \) undergoes combustion to form carbon dioxide and water when it is used in the oxyacetylene torch for welding. Write a balanced equation to represent this reaction. How many grams of water can be formed if \( 113 \mathrm{~g} \) of acetylene is burned? How many grams of acetylene react if \( 1.10 \) moles of carbon dioxide are produced? 3. Sodium hydroxide is neutralized with sulfuric acid. Write a balanced equation to represent this reaction. How many grams of sodium sulfate will be formed if you start with 200 , grams of sodium hydroxide and you have an excess of sulfuric acid? 4. Lead (IV) sulfate reacts with lithium nitrate. Write a balanced equation to represent this reaction. How many grams of lithium nitrate will be needed to make 250. grams of lithium sulfate, assuming that you have an adequate amount of lead (IV) sulfate? 5. Use the following balanced reaction to answer the remaining questions: \[ 2 \mathrm{C}_{6} \mathrm{H}_{10}+17 \mathrm{O}_{2} \rightarrow 12 \mathrm{CO}_{2}+10 \mathrm{H}_{2} \mathrm{O} \] How many grams of carbon dioxide will be formed if \( 35.0 \) grams of \( \mathrm{C}_{6} \mathrm{H}_{10} \) reacts with \( 45.0 \) grams of oxygen? What is the limiting reactant? How much of the excess reactant is left over after the reaction is finished? If \( 35.0 \) grams of carbon dioxide are actually formed from the reaction, what is the percent yield of the reaction?
