Question

The following equation represents which of the following types of reaction?

Answer 1

Answer:

A. decomposition.

Explanation:

Recall the types of chemical reactions and how they are typically written.

Synthesis : A + B ==> AB

Decomposition : AB ==> A + B

Double Replacement : AB + CD ==> AC + BD

Single Replacement : AB + C ==> AC + B

Now although it may seem that the given equation doesnt follow any of these as it has more parts, it follows decomposition.
Decomposition is simply a single compound being broken up into two or more products. So it can be written as ABC ==> A + B + C as well therefore the answer is A
