Question

fill in the blank coefficient in order to balance the following chemical equation. your answers should be whole numbers. provide your answer below: h₂ + o₂ → h₂o

Explanation:

Step1: Balance oxygen atoms

On the left - hand side, there are 2 oxygen atoms in $O_2$. On the right - hand side, there is 1 oxygen atom in $H_2O$. To balance the oxygen atoms, we put a 2 in front of $H_2O$: $H_2+O_2
ightarrow2H_2O$.

Step2: Balance hydrogen atoms

Now, on the right - hand side, there are 4 hydrogen atoms in $2H_2O$. On the left - hand side, there are 2 hydrogen atoms in $H_2$. So we put a 2 in front of $H_2$: $2H_2 + O_2
ightarrow2H_2O$.

Answer:

2, 2
