Question 1

Lithium and nitrogen react in a combination reaction to produce lithium nitride:

6Li(s) + N₂(g) → 2Li₃N(s)

In a particular experiment, 5.50 g samples of each reagent are reacted. What is the theoretical yield of lithium nitride?
◦ 3.42 g
◦ 9.20 g
◦ 4.60 g
◦ 27.6 g
◦ 13.7 g

Question 2

Calcium oxide reacts with water in a combination reaction to produce calcium hydroxide:

CaO(s) + H₂O(l) → Ca(OH)₂(s)

A 4.50 g sample of CaO is reacted with 4.34 g of H₂O. How many grams of water remain after the reaction is complete?
◦ 0.241 g
◦ 0.161 g
◦ 1.45 g
◦ 2.89 g
◦ 0.00893 g
