Question 1

wPCl₅ + xH₂O → yPOCl₃ + zHCl

The above equation is properly balanced when:

◦ w = 1, x = 2, y = 2, z = 4
◦ w = 2, x = 2, y = 2, z = 2
◦ w = 2, x = 2, y = 2, z = 1
◦ w = 1, x = 1, y = 1, z = 2
◦ none of these are correct

Question 2

You heat 3.886 g of a mixture of Fe₃O₄ and FeO to form 4.095 g Fe₂O₃. The mass percent of FeO originally in the mixture was

◦ 94.9%.
◦ 26.1%.
◦ 73.9%.
◦ 18.0%.
◦ None of these are correct.
