Analysis:
Marble is made from limestone under the influence of heat and pressure. The chemical formula for limestone or marble
chips is CaCO3. When you added the chips to the acid solutions, they effervesced (bubble or foam).
1. What is the gas that is produced?
2. What is the chemical formula of the gas?
3. How could you test rocks for the presence of limestone?
4. Write a balanced symbol model for the reaction of limestone with hydrochloric acid.

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
