How many sulfur atoms do you need for this reaction to produce 1 molecule of CS2 and 2 molecules of H2S?

1CH4 + 0S → 1CS2 + 2H2S

a
1
b
2
c
3
d
4

c. 3

To balance the chemical equation, we need to make sure that the number of atoms on both sides of the equation is equal. Looking at the equation provided:

1CH4 + 0S → 1CS2 + 2H2S

On the left-hand side, we have 1 carbon (C), 4 hydrogen (H), and 0 sulfur (S) atoms.

On the right-hand side, we have 1 carbon (C), 4 hydrogen (H), and 2 sulfur (S) atoms.

To balance the equation, we need to add sulfur atoms to the left-hand side of the equation. We need 2 sulfur atoms to produce 2 molecules of H2S on the right-hand side of the equation.

Therefore, the answer is b) 2.

To determine the number of sulfur atoms needed for the reaction, we can analyze the balanced chemical equation:

1CH4 + 0S → 1CS2 + 2H2S

According to the equation, 1 molecule of CS2 is produced from the reaction. In CS2, we have 1 carbon (C) atom and 2 sulfur (S) atoms. Therefore, we need 2 sulfur atoms for 1 molecule of CS2.

Hence, the answer is option b: 2 sulfur atoms.
