Question

In the chemical reaction, calcium carbonate (caco3) was heated to form two new substances: calcium oxide (cao) and carbon dioxide (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?.

Answer 1

Answer: 10.99 g.

Step-by-step explanation:

Molecular mass of CaO = 56.07 g

CO = 44.01 g

Gas that escaped = 13.9 x 44.01/ 56.07
