How many sulfur atoms do you need for this reaction to produce 1 molecule of CS2 and 2 molecules of H2S
A. 1
B. 2
C. 3
D. 4
The reaction in question is:
CS2 + 3 H2S -> 4 H2O + CH4.
In this reaction, there is one molecule of CS2 produced and two molecules of H2S produced.
Since there is 1 molecule of CS2, we need 1 sulfur atom.
Since there are 2 molecules of H2S, we need 2 sulfur atoms.
Therefore, the total number of sulfur atoms needed for this reaction is 1 + 2 = 3.
The correct answer is C. 3.
To determine the number of sulfur atoms needed for the reaction, we need to balance the chemical equation for the reaction.
The balanced chemical equation for the reaction is:
1 CS2 + 4 H2S → 1 CS2 + 4 H2S
From the balanced equation, we can see that 1 molecule of CS2 and 2 molecules of H2S are produced. This means that we need 4 sulfur atoms (from 2 molecules of H2S) to produce this combination of products.
Therefore, the correct answer is:
D. 4
To find out how many sulfur atoms you need for this reaction, we first need to look at the balanced chemical equation for the reaction.
The chemical equation for the reaction that produces 1 molecule of CS2 and 2 molecules of H2S can be written as:
1 CS2 + X S + 2 H2S → X CS2 + 2 X H2S
Here, X represents the number of sulfur atoms required.
From the equation, it is clear that for every molecule of CS2 produced, one sulfur atom is needed. Similarly, for every 2 molecules of H2S produced, X sulfur atoms are required.
Since we need X sulfur atoms for 2 molecules of H2S, we can set up a ratio:
1 CS2 : 2 H2S = 1 : X
Cross-multiplying, we get:
1 * X = 1 * 2
X = 2
Therefore, we need 2 sulfur atoms to produce 1 molecule of CS2 and 2 molecules of H2S.
The answer is B. 2.
