Question

How many sulfur atoms do you need for this reaction to produce 1 molecule of CS, and 2 molecules of H25?

Answer 1

To determine how many sulfur atoms are needed to produce 1 molecule of carbon disulfide (CS₂) and 2 molecules of hydrogen sulfide (H₂S), we can write the chemical reactions involved.

1. The formation of carbon disulfide (CS₂):
\[
C + 2S \rightarrow CS₂
\]
This reaction consumes 2 sulfur atoms to produce 1 molecule of CS₂.

2. The formation of hydrogen sulfide (H₂S):
\[
H₂ + S \rightarrow H₂S
\]
Each molecule of H₂S requires 1 sulfur atom. Therefore, producing 2 molecules of H₂S would require:
\[
2 \times S = 2S
\]

Now, combining these requirements:
- For 1 molecule of CS₂: 2 sulfur atoms
- For 2 molecules of H₂S: 2 sulfur atoms

Adding those up gives us:
\[
2 \text{ (for CS₂)} + 2 \text{ (for H₂S)} = 4 \text{ sulfur atoms}
\]

Thus, you need a total of **4 sulfur atoms** to produce 1 molecule of CS₂ and 2 molecules of H₂S.
