1. Hydrogen is produced when methane (CH4) reacts with water. The other product is CO2. Using 80.0 grams of methane and 16.3 g of water, how many liters of H2 can be
produced at STP? What is the limiting reactant? What is the percent yield if the actual yield is 28.5 L of H2?

2. Methyl alcohol (CH3OH) is made by reacting carbon monoxide with H2. Starting with 2.5 g of H2 and 30.0 L of CO, what mass of methyl alcohol could be produced at STP?
Which is the limiting reactant? What is the percent yield if 15.6g of methyl alcohol is produced?

3. In a reaction of 15.3 g of NaCl with 60.8 g of Pb(NO3)2, how many grams of lead (II)
chloride will be produced? What is the limiting reactant? What is the percent yield if 2.65g of PbCl2 are produced?

4. Diborane (B2H6) is widely used in the synthesis of organic compounds. Diborane itself
is made by the reaction 2NaBH4 + I2 → B2H6 + 2NaI + H2. If 6.3 g of NaBH4 are
reacted with excess I2, how many grams of diborane could theoretically be isolated? If
1.9 g of diborane is actually produced, what is the percent yield of the reaction?
