Question 1

Magnesium burns in air with a dazzling brilliance to produce magnesium oxide:

2 Mg(s) + O₂(g) → 2 MgO(s)

When 4.00 g of magnesium burns, what is the theoretical yield of magnesium oxide?
◦ 4.00 g
◦ 6.63 g
◦ 0.165 g
◦ 3.32 g
◦ 13.3 g

Question 2

Nitroglycerin, used both in medicine and as an explosive, can be prepared by the carefully controlled reaction of glycerol (C₃H₈O₃) with nitric acid, as symbolized by:

C₃H₈O₃ + 3 HNO₃→ C₃H₅N₃O₉ + 3 H₂O

What mass of nitric acid is required for the production of 2.8 g of nitroglycerin by a process having a 67% yield?
◦ 2.3 g
◦ 0.39 g
◦ 1.6 g
◦ 3.5 g
