When Kay added 30 g of hydrochloric acid (HCl) to 65 g of Zn, bubbles appeared and a white precipitate, zinc chloride (ZnCl2) was produced. She found that the mass of the zinc chloride was 63 g. Since the Law of Conservation of Matter stated that matter can't be created or destroyed, she was puzzled about the difference in mass. What is the best explanation for the missing 2 g?
A) 2 g of zinc disappeared.
B) 2 g of hydrogen gas were produced.
C) Kay didn't correctly mass the precipitate.
D) Kay didn't collect all of the precipitate.
