In the chemical reaction, calcium carbonate (CaCO3) was heated to form two new substances: calcium oxide (Cao) and carbon dioxide (CO2).
CaCO3 + CaO + CO2
A student heated 24.8 g of CaCO3. After the reaction, they measured 13.9 g of Cao.
What was the mass of the CO2 gas that escaped during the reaction?
38.79
O 1.78 g
0 24.8 g
10.99

3.09 lab: reaction of metals 1 which combinations of substances resulted in a chemical change? for each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. make a general statement about the reactivity of the metals in this experiment.
