Gas Stoichiometry

Acetylene gas () is normally prepared in the lab by reacting calcium carbide () with water. What mass of calcium carbide is required to produce of acetylene gas at STP?
*solution

All together:

of Zinc reacts with hydrochloric acid to produce aqueous zinc chloride and hydrogen gas. Determine the volume of hydrogen gas produced at STP conditions.

solution

of magnesium reacts with of sulphuric acid to produce aqueous magnesium sulphate and hydrogen gas. Determine the volume of hydrogen gas produced at STP conditions.

solution

Since , is the limiting reagent.
