Answer:
Carbon Dioxide Reactants
Only two materials are needed to make carbon dioxide:
calcium carbonate (marble chips)
5M hydrochloric acid
Carbon Dioxide Gas Preparation
Add 5M hydrochloric acid to 5g-10g marble chips. Carbon dioxide gas is released by the chemical reaction.
Collect the carbon dioxide from the upward displacement of air in a hood. Carbon dioxide is about 60% denser than air, so it will fill the reaction container.
Chemical Reaction
2HCl + CaCO3 → CO2 + CaCl2 + H2O
