Just give me the last step solutions(make the solution shortest) and give me the answer. Thank you.
(Worksheet M4/18)
Reacting masses, Molar volume and combining gas laws
Directions: Use the gas laws we have learned to solve each of the following problems. Each of
the chemical equations must first be balanced. Show all your work.
1. When calcium carbonate is heated strongly, carbon dioxide gas is released according to
the following equation:
CaCO3(s) CaO(s) + CO₂(g)
What volume of CO₂(g), measured at STP, is produced if 15.2 grams of CaCO,(s) is heated?
