Question

Which of the following combinations of coefficients correctly balances this chemical equation: 2H2S (g) + __O2 (g) __CO2 (g) + 2H2O (g)?

1, 2

2, 3

2, 2

3, 2

Answer 1

Salutations. ^^

The answer is C. 3,2 since you would be balancing out the Oxygen (O2) & Sulfur (S) elements on both sides.

Although this may be late, I hope this helps future viewers~♥

Answer 2

I think the correct answer from the choices listed above is the last option. The combinations of coefficients that correctly balances the chemical reaction would be 3,2. BY the way, it should not be CO2, it should be SO2. Hope this answers the question. Have a nice day.
