Question

what is the missing coefficient to make a balanced equation? c + ?s → cs₂ 4 1 2 7

Explanation:

Step1: Analyze sulfur atoms

On the right - hand side of the equation in $CS_2$, there are 2 sulfur atoms.

Step2: Determine sulfur coefficient

To balance the sulfur atoms, since each sulfur molecule is $S$, the coefficient of $S$ on the left - hand side must be 2 so that the number of sulfur atoms on both sides of the equation is equal. And the coefficient of $CS_2$ is 1 to balance the carbon atoms.

Answer:

The coefficient of $S$ is 2 and the coefficient of $CS_2$ is 1. So the answer for the missing coefficient of $S$ is 2.
