A 10.0 gram sample containing calcium carbonate and an inert material was placed in excess hydrochloric acid. A reaction occurred producing calcium chloride, water, and carbon dioxide.

a. Write the balanced equation for the reaction.

b. When the reaction was complete, 900 milliliters of carbon dioxide gas were collected at 740 mmHg and 30 degrees C. How many moles of calcium carbonate were consumed in the reaction?

c. If all of the calcium carbonate initially present in the sample was consumed in the reaction, what percent by mass of the sample was due to calcium carbonate?

d. If the inert material was silicon dioxide, what was the molar ratio of calcium carbonate to silicon dioxide in the original sample?
