a student wrote a chemical equation as shown.

2h2s + 3o2 → h2o + so2

what should the student do to balance the equation?

add a coefficient 4 before h2o and a 2 before so2.
add a coefficient 2 before h2o and a 4 before so2.
add a coefficient 5 before h2o and a 4 before so2.
add a coefficient 2 before h2o and a 2 before so2.

2H2S + 3O2 → H2O + SO2

We have 4 H on the left and 2 on the right

2 S on the left and 1 on the right

6 O on the left and 3 on the right

We need to multiply everything on the right  by 2

Add a coefficient 2 before H2O and a 2 before SO2.

2H2S + 3O2 → 2H2O + 2SO2

4H  4H

2S = 2S

6O =2O
