Question

caco₃ (s) + 2hcl (aq) → cacl₂ (aq) + co₂ (g) + h₂o (l)
in the chemical reaction above, what states are caco₃ and h₂o at respectively?
a gas, liquid
b solid, liquid
c solid, aqueous
d gas, aqueous
e aqueous, solid

Explanation:

Step1: Identify the state of \(CaCO_3\)

In the chemical formula \(CaCO_3(s)\), the \(s\) stands for solid.

Step2: Identify the state of \(H_2O\)

In the chemical formula \(H_2O(l)\), the \(l\) stands for liquid.

Answer:

B. Solid, Liquid
