Answer 2

The balanced chemical equation for the reaction between calcium (Ca) and oxygen (O2) to form calcium oxide (CaO) is as follows:

2Ca + O2 -> 2CaO

The stoichiometric coefficients in this balanced equation are as follows:

• For calcium (Ca): 2
• For oxygen (O2): 1
• For calcium oxide (CaO): 2

To calculate the sum of the coefficients, you simply add them up:

Sum of coefficients = 2 + 1 + 2 = 5

So, the sum of the coefficients for the reaction Ca + O2 -> CaO is 5.
