One molecule of calcium oxide, CaO , and one molecule of carbon dioxide, CO2 , combine in a chemical reaction to form one substance. Given that matter is neither created nor destroyed, which chemical formula identifies the product of this reaction?(1 point)

Question

Responses

CaCO2
C a C O sub 2

Ca2O3
Ca sub 2 O sub 3

Ca2CO3
Ca sub 2 C O sub 3

CaCO3

Answer 1

The reaction between calcium oxide (CaO) and carbon dioxide (CO2) produces calcium carbonate (CaCO3). The balanced chemical reaction can be represented as:

\[ \text{CaO} + \text{CO}_2 \rightarrow \text{CaCO}_3 \]

Thus, the correct chemical formula for the product of this reaction is CaCO3.
