select the correct answer. copper carbonate (cuco₃) reacts with hydrochloric acid (hcl) according to this equation: cuco₃(s) + 2hcl(aq) → cucl₂(aq) + h₂o(l) + co₂(g). which statement correctly describes the substances in this reaction? a. exactly one product and two reactants are either liquid or dissolved in water. b. exactly one of the reactants is in a water - based solution, but none of the products are. c. the reactants include both a liquid and a gas. d. exactly one reactant is a solid, and exactly one product is a gas. e. the products include a solid, a liquid, and a gas.

Answer

Explanation:

Step1: Identify reactants and products states

Reactants are $\mathrm{CuCO_3}(s)$ (solid) and $2\mathrm{HCl}(aq)$ (aqueous - dissolved in water). Products are $\mathrm{CuCl_2}(aq)$ (aqueous), $\mathrm{H_2O}(l)$ (liquid) and $\mathrm{CO_2}(g)$ (gas).

Step2: Analyze option A

There are two products ($\mathrm{CuCl_2}(aq)$ and $\mathrm{H_2O}(l)$) and one reactant ($\mathrm{HCl}(aq)$) that are either liquid or dissolved in water, so A is incorrect.

Step3: Analyze option B

One reactant ($\mathrm{HCl}(aq)$) is in a water - based solution and two products ($\mathrm{CuCl_2}(aq)$ and $\mathrm{H_2O}(l)$) are related to water (dissolved or liquid), so B is incorrect.

Step4: Analyze option C

Reactants are solid and aqueous, no liquid or gas reactants, so C is incorrect.

Step5: Analyze option D

One reactant $\mathrm{CuCO_3}(s)$ is solid and one product $\mathrm{CO_2}(g)$ is gas, so D is correct.

Step6: Analyze option E

Products are aqueous, liquid and gas, no solid product, so E is incorrect.

Answer:

D. Exactly one reactant is a solid, and exactly one product is a gas
