Answer 1

Answer:

C. an acid  

Explanation:

just did the test on edge

Answer 2

Acidic substance reacts with limestone and produces carbon dioxide gas.

• Limestone is a base. When it reacts with an acid like HCl it evolves carbon dioxide gas.
• The balanced chemical reaction is as follows-
• $CaCO_3+2HCl\rightarrow CaCl_2+H_2O+CO_2$.
• Thus in this reaction, one mole of calcium carbonate reacts with two moles of HCl to produce one mole of calcium chloride along with one mole of water and one mole of carbon dioxide gas.
