Chapter 7.2, Problem 2CP

Which of the following equations correctly represent the chemical reaction in which graphite combines with sulfur to form carbon disulfide gas $\left[{\text{CS}}_{\text{2}}\left(\text{g}\right)\right]\text{?}$ (Select all that apply.)

a)

$\text{C}\left(\text{graphite}\right)\text{ + 2S}\left(s\right)\to {\text{ CS}}_{\text{2}}\left(g\right)$

b)

$\text{C}\left(\text{graphite}\right){\text{ + S}}_{\text{2}}\left(s\right)\to {\text{ CS}}_{\text{2}}\left(g\right)$

C)

$\text{C}\left(\text{graphite}\right){\text{ + S}}_8\left(s\right)\to {\text{ CS}}_8\left(g\right)$

d)

$\text{C}\left(\text{graphite}\right)\text{ + }\frac{1}{4}{\text{S}}_8\left(s\right)\to {\text{ CS}}_2\left(g\right)$

e)

$\text{4C}\left(\text{graphite}\right){\text{ + S}}_8\left(s\right)\to {\text{ 4CS}}_2\left(g\right)$
