What coefficient is needed in front of the Carbon (C) in the reactants in order to balance the equation?

C + 2SO2 --> CS2 + 4CO

5
6
4
3

Hint: The number of atoms in the reactant, must equal the number of atoms in the product, for each element

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

i think slash and

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
