Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical
equation:
( )H2O = ( ) H2 + ( ) O2
Options: 1 , 2 , 3

2, 2, 1

Explanation:

The coefficient of H₂O will be 2 because we have 2 oxygens on the right side but only one on the left side. Now, we have 4 hydrogens on the left side but only 2 on the right side. To balance, we'll add a 2 as the coefficient of H₂. We don't need to change the coefficient of O₂ because the equation is already balanced.

Final answer, 2, 2, 1.

it should be all of them because it asks if you included all of those in your answer
