Question

Which coefficients correctly balance the formula equation CaO + H₂O → Ca(OH)₂?

a. 2, 1, 2
b. 1, 2, 3
c. 1, 2, 1
d. 1, 1, 1

Answer 1

The correct coefficients that balance the equation are 2, 1, 2.

Step-by-step explanation:

To balance the formula equation CaO + H₂O → Ca(OH)₂, we need to adjust the coefficients. The correct coefficients are a. 2, 1, 2. This means that the balanced equation is 2CaO + H₂O → Ca(OH)₂.
