Question 1

Lithium metal reacts with nitrogen gas to form lithium nitride. Identify the balanced reaction that describes this process.
◦ Li + N → LiN
◦ Li + N2→ LiN2

◦ 2Li + N2→ Li2N2

◦ 6Li + N2→ 2Li3N
◦ 2Li + N2→ 2LiN

Question 2

One way of obtaining pure sodium carbonate is through the decomposition of the mineral trona, Na 3(CO3)(HCO3)⋅2H2O, as shown in the following reaction:
         2Na3(CO3)(HCO3)⋅2H2O(s) → 3Na2CO3(s) + CO2(g) + 5H2O(g)
When 15 metric tons (1 × 103 kg) of trona is decomposed, 11 metric tons of Na2CO3 is recovered.  What is the percent yield of this reaction? (1 metric ton = 103 kg)
◦ 13%
◦ 42%
◦ 65%
◦ 73%
◦ 95%
