Question

CaCo3+2HCL[dil.]=CaCl2+H2O+CO2[g] what is the information provided by this equation and state the information not conveyed by the chemical equation

Answer 1

When dilute acids react with metallic carbonates and bicarbonates , carbon dioxide is produced

Answer 2

Answer: The physical states of the compounds are not conveyed.

Explanation:

We are given a chemical reaction:

$CaCO_3+2HCl\rightarrow CaCl_2+H_2O+CO_2(g)$

From the above equation, it can be conveyed that a metal carbonate when reacted with an acid, produces a salt, carbon dioxide and water.

And also, the physical states of the substances are not written in the equation, which is a must.

The chemical equation for the above reaction including physical states are:

$CaCO_3(s)+2HCl(aq.)\rightarrow CaCl_2(s)+H_2O(l)+CO_2(g)$
