Answer:
The answer to your question is the fourth one.
Explanation:
From the description, we know that the reactants are two liquids and the products are a solid and a gas.
The first option is incorrect because it mentions that the reactants are one liquid and solid.
The second option is also incorrect for the same reason as the first one and one of the products must be a solid.
The third option is incorrect besides there are two liquids in the reactants and a solid and gas in the liquids there is a minus sign that is not possible.
The fourth option is the correct one.
