The correct chemical formula for the product of this reaction is CaCO3, calcium carbonate.
The chemical formula of the product formed when one molecule of calcium oxide (CaO) and one molecule of carbon dioxide (CO2) combine in a chemical reaction is CaCO3.
To determine the chemical formula of the product formed in the reaction between calcium oxide (CaO) and carbon dioxide (CO2), we first need to understand the reactants and the reaction itself.
In the reaction, calcium oxide (CaO) and carbon dioxide (CO2) combine to form a product. The chemical equation for this reaction can be represented as follows:
CaO + CO2 -> Product
Now, let's analyze the reactants:
Calcium oxide (CaO) is composed of one calcium atom (Ca) bonded to one oxygen atom (O).
Carbon dioxide (CO2) is composed of one carbon atom (C) bonded to two oxygen atoms (O).
To determine the chemical formula of the product, we need to understand the nature of the bonding and the stoichiometry of the reaction. In this case, calcium oxide (CaO) is a basic oxide, and carbon dioxide (CO2) is an acidic oxide. When they react, they typically form a salt.
The product of this reaction will be a compound containing calcium (Ca) and carbonate (CO3) ions. The carbonate ion (CO3^2-) is composed of one carbon atom (C) bonded to three oxygen atoms (O).
By matching the charges of the ions, we find that it takes two calcium ions (Ca^2+) to balance the charge of one carbonate ion (CO3^2-). Therefore, the correct chemical formula for the product is:
CaCO3
So, option D, CaCO3, is the correct answer.
