Question

Calcium oxide (CaO) can react with carbon dioxide (CO2) in a synthesis reaction. Select the most likely products of this reaction. CaO + CO2 → ?

Answer 1

First section is B, Second section is also B

Step-by-step explanation:

Answer 2

CaCO3

In a synthesis reaction, two substances combine to make a third substance:

A + B → C

The product (C) must contain all the atoms that were in A and B.

Thus, the reaction must be

CaO + CO2 → CaCO3

The product is CaCO3.
