Answer 2

The chemical equation you've provided appears to be incomplete, as it lacks specific reactants and coefficients. A balanced chemical equation typically includes reactants on the left side and products on the right side, with coefficients representing the relative amounts of each substance involved in the reaction.

To balance this equation, we need to specify the reactants and their coefficients. Assuming you want to describe the reaction where calcium (Ca) reacts with oxygen (O2) to form calcium oxide (CaO), the balanced equation would look like this:

2 Ca + O2 → 2 CaO

In this balanced equation:

• There are 2 atoms of calcium (Ca) on both sides.
• There are 2 atoms of oxygen (O) on both sides.
• Calcium oxide (CaO) is the product.

The coefficients ensure that mass is conserved, and the number of atoms of each element is the same on both sides of the equation.
