Answer:
5. First option
Explanation:
The number of atoms in the reactant, must equal the number of atoms in the product, for each element
C + 2SO₂ → CS₂ + 4CO
In product side you have 1 C from the sulfure and 4 C from the CO.
As you have 5C in the product side, you need 5C in the reactant side.
the balanced equation is: 5C + 2SO₂ → CS₂ + 4CO
