Balance the following reactions that occur among volcanic gases

SO2(g) + O2(g) → SO3(g)

Balance O

SO2(g) +  1/2 O2(g) → SO3(g)

Make coefficient whole numbers by multiplying 2.

[SO2(g) +  1/2 O2(g) → SO3(g)] x 2

The balanced reaction is:

SO2(g) + O2(g) → 4 SO3(g)

H2S(g) + O2(g) → SO2(g) +H2O(g)

Balance O

H2S(g) + 3/2 O2(g) → SO2(g) +H2O(g)

Make coefficient whole numbers by multiplying 2.

[H2S(g) + 3/2 O2(g) → SO2(g) +H2O(g)] x 2

The balanced reaction is:

H2S(g) + 3 O2(g) →2 SO2(g) +H2O(g)
