Complete Question
The complete question is shown on the first uploaded image
Answer:
The pressure is 
Explanation:
From the question we are told that
The mass of the carbon monoxide is 
The temperature at which takes place 
The volume of the sealed vessel is 
Generally the ideal gas law is mathematically represented as

Where R is the gas constant with value 
n is the number of moles of carbon monoxide which is mathematically evaluated as

where
is the molar mass of carbon monoxide which is a constant with value

So 

Now Making P the subject we have


THE ANSWER IS B. The reducing of oxidation state (-1 to -2, a change of -1, a REDUCTION) is what makes it a reduction.
4 moles
Explanation:
Given parameters:
number of moles of reacting NO = 24moles
Equation of the reaction:
4C₃H₆ + 6NO ⇒ 4C₃H₃N + H₂O + N₂
Solution:
The moles is synonymous the quantity of matter that contains the avogadro's number of particles.
To solve this problem, we must ensure that the given equation is balanced by simply inspecting.
The equation is balanced by inspection.
From the balanced equation;
6 moles of NO reacted to produce 1 mole of nitrogen gas
24 moles of NO will therefore produce
= 4 moles
