The explanation is shown in the image attached with
One mole of CS₂ and two moles of H₂S are formed as products and 3 moles of CH₄ are leftover.
<h3>What is the limiting reagent?</h3>
A limiting reagent is a reactant that is fully exhausted from the reaction mixture at the completion of a reaction. The limiting reactant will decide the maximum amount of product.
Given, a balanced chemical equation of the reaction between methane and sulphur is:

Given, the number of moles of the sulphur = 4
The number of moles of methane = 4
From the chemical reaction, one mole of methane reacts with four moles of sulphur. Therefore, four moles of sulphur fully react with one mole of methane and three moles of methane leftover.

4-nonanone
Explanation: there is a functional group in the compound CH3CH2CH2CH2CH2COCH2CH2CH3 which is a ketone; So for naming a ketone we must first mention the name of the prefix that is correspond then add the suffix ''one''. And why I putted a ''4'' before the name is because we must indicate where this functional group is located, for doing that we have to start counting where the functional group is the closet to the end of the compound so when looking we should start to count on the right side. this is how I get 4-nonanone
The given question is an incomplete question, the complete question is given below.
Use this equation to answer the questions that follow.

5 moles of oxygen gas are present. How many moles of
will be produced with this amount of oxygen gas?
Answer : The moles of
produced will be 3.33 moles.
Explanation : Given,
Moles of oxygen gas = 5 moles
Now we have to calculate the moles of
.
The given balanced chemical equation is:

From the balanced chemical equation we conclude that,
As, 3 moles of
gas react to produces 2 moles of
gas
So, 5 moles of
gas react to produces
moles of
gas
Therefore, the moles of
produced will be 3.33 moles.
