what is the correct coefficient for h₂o when balancing the equation ch₄ + 2o₂ → co₂ + h₂o?\na. 2\nb. 1\nc. 4\nd. 3
Answer
Explanation:
Step1: Count hydrogen atoms on left - hand side
The reactant $CH_4$ has 4 hydrogen atoms.
Step2: Balance hydrogen atoms
To balance hydrogen atoms on the right - hand side in $H_2O$, since each $H_2O$ molecule has 2 hydrogen atoms, we need 2 $H_2O$ molecules to get 4 hydrogen atoms.
