Question

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

Explanation:

Step1: Analyze carbon atoms

On the right - hand side of the equation $CS_2$, there is 1 carbon atom. So, the coefficient of C on the left - hand side should be 1 to balance the carbon atoms.

Step2: Analyze sulfur atoms

On the right - hand side, there are 2 sulfur atoms. So, the coefficient of S on the left - hand side should be 2 to balance the sulfur atoms. The balanced equation is $1C + 2S
ightarrow1CS_2$.
