Question

Answer the following questions​

Answer 1

Answer:

1)In laboratory, carbon dioxide is not obtained from the air, carbon dioxide is prepared from carbonates by adding acids to the carbonates. In this experiment carbon dioxide is prepared by the reaction of marble with hydrochloric acid.

2) CaCO3+2HCl→CaCl2+H2O+CO2.

3) Carbon dioxide is produced whenever an acid reacts with a carbonate. This makes carbon dioxide easy to make in the laboratory. ... Carbon dioxide is slightly soluble in water and denser than air, so another way to collect it is in a dry, upright gas jar.
