Question

In the reaction CaCl₂ (s) + Cl₂ (g) → CaCl₂ (s) + I₂ (s), what phases are the products in after the reaction?

A) CaI₂ is a solid, and CaCl₂ is in aqueous solution.
B) CaCl₂ is a liquid, and I₂ is a gas.
C) Both products are solids.
D) Both products are liquids.

Answer 1

The products of the reaction CaCl₂ (s) + Cl₂ (g) → CaCl₂ (s) + I₂ (s) are CaCl₂ in a solid state and I₂ in a solid state.

Step-by-step explanation:

The products of the reaction CaCl₂ (s) + Cl₂ (g) → CaCl₂ (s) + I₂ (s) are CaCl₂ in a solid state and I₂ in a solid state. In this reaction, the solid CaCl₂ does not change its state and remains as a solid in the products. On the other hand, the gaseous Cl₂ reacts with CaCl₂ to form solid I₂.
