Question

Classify the reaction in each of the following equations.

a. BaCl2 (aq) + K2CrO4 (aq) → BaCrO4 (s) + 2KCl(aq)


b. Si(s) + 2Cl2 (g) → SiCl4 (l)

Answer 1

a) Double replacement

b) Synthesis

Step-by-step explanation:

a) For A, we have two ionic reactants that form two ionic products, where the anion (or cation) is swapped. This is a characteristic of a double replacement reaction.

b) For B, two elements, this time two elements, react together to form one product that's unlike the reactants. This is a characteristic of a synthesis reaction.
