Question

How would you balance this equation?
____Ca + ____ O2 = ____ CaO

Answer 1

Answer:

2Ca+2O2->2CaO

Explanation:

You have 2 O’s on the left side so you multiply the right side by 2.

Ca + O2 -> 2CaO

Now that you have 2 Ca on the right side and only 1 on the left, you multiply the Ca on the right by 2.

2 Ca + O2 -> 2 CaO
