Answer: 2 H₂ + O₂ ⇒ 2 H₂O

Step-by-step explanation:

H₂ + O₂ ⇒ H₂O

There needs to be the same amount of each atom on both sides of the equation.

Step 1

There are 2 oxygen atoms on the left side of the equation and 1 oxygen atom on the right side of the equation.

Place a 2 in front of H₂O on the right side of the equation to balance the oxygen atoms.

H₂ + O₂ ⇒ 2 H₂O

Now the oxygen atoms are balanced, with 2 on each side of the equation.

Step 2

H₂ + O₂ ⇒ 2 H₂O

There are 2 hydrogen atoms on the left side of the equation and 4 hydrogen atoms on the right side of the equation (2 x 2 = 4).

Place a 2 in front of H₂ on the left side of the equation.

2 H₂ + O₂ ⇒ 2 H₂O

Now the hydrogen atoms are balanced.

The entire equation is balanced because there are equal numbers of each atom on both sides of the equation.
