Question 1

When 11.0 g of calcium metal is reacted with water, 5.00 g of calcium hydroxide is produced. Using the following balanced equation, calculate the percent yield for the reaction.

Ca(s) + 2H2O(l) → Ca(OH)2(aq) + H2(g)

◦ 12.3%
◦ 45.5%
◦ 24.6%
◦ 84.0%

Question 2

7.0 g of nitrogen is reacted with 5.0 g of hydrogen to produce ammonia according to the chemical equation shown below. Which one of the following statements is FALSE?
 
N2(g) + 3H2(g) → 2NH3(g)

◦ Nitrogen is the limiting reactant.
◦ The theoretical yield of ammonia is 15 g.
◦ 3.5 g of hydrogen are left over.
◦ Hydrogen is the excess reactant.
