Question

CaCO3 + 2HCl → CaCl2 + H2O + CO2(g)

4a. Give in the reactants in the above equation.

4b. State which characteristic does [g] in the above reaction indicates.

4c. Write the word equation of the above mentioned equation.

4d. What does the arrow in represents.
​

Answer 1

Answer:

Reactant is Calcium carbonate (CaCO3) and Hydrochloric acid (HCL)

When Calcium carbonate and Hydrochloric acid react formation of Carbon dioxide (CO2) gas take place which is used as fire extinguisher

Calcium carbonate (CaCO3) + Hydrochloric acid (HCL) → Water (H2O) + Carbon dioxide (CO2)

Arrow (→) represent that the formation of products by Reactoin of reactant
