Question

Balance the following equation:
!!!!

Answer 1

CaC2 + 2H2O > C2H2 + Ca(OH)2

Step-by-step explanation:

Count the amounts of Ca, C, H, and O, all separately on both sides.

Ca: 1 Ca: 1

C: 2 C:2

H: 2 H: 4

O: 1 O: 2

Now, your goal is to get both sides equal to each other by adding a 2 in front of H2O.
