Which is the next logical step in balancing the given equation?

3CO(g) + Fe2O3(s) Fe(s) + 3CO2(g)

THIS IS THE BEST ANSWER 👇

CS2 (l) + Cl2 (g) → CCl4 (l) + S2Cl2 (l)

The next logical step in balancing the above equation is to place the coefficient 3 in front of the chlorine molecule (answer B)

Explanation

When a coefficient of 3 is placed in front of a chlorine molecule the equation is balanced as below

CS2 (l) + 3Cl2 (g) → CCl4 (l) + S2Cl2 (l)
According to the law of mass conservation the number of atoms on the reactant side should be equal to the product side. The above reaction is balanced because the number of atoms is equal on both sides.
For example there are 2 S atoms on the product side and 2 S atoms in the product side
