Balance the chemical equation:

_CaC₂ + _H₂O - _C₂H₂ + _ Ca(OH)₂

Question

Balance the chemical equation:

_CaC₂ + _H₂O -> _C₂H₂ + _ Ca(OH)₂

jhonyy9 · Answer

so like a first step on the left side there are 2 hidrogen atoms with 1 oxigen 
and on the right side there are 4 hidrogen atoms with 2 oxigen

how can you balance these ? any idea ?

Hey, here's your answer

CaC₂ + 2H₂O -> C₂H₂ + Ca(OH)₂

Explanation:

First, we put 2 in as a coefficient in front of our H₂O.

Then, we double the Hydrogens 2 x 2 = 4 and 2 + 2 = 4 (so both (H) sides equal 4)
 Then, we double the Oxygens 1 x 2 = 2 and o = 2 (so both (O) sides equal 2)
 
 Finally, after we balance the chemical equation it will look like this:
  CaC₂ + 2H₂O -> C₂H₂ + Ca(OH)₂
