According to the task, you are proveded with patial pressure of CO2 and graphite, and here is complete solution for the task :
At first you have to find n1 =moles of CO2 and n2 which are moles of C
<span>The you go :
</span>

n1 n2 0
-x -x +2x

After that you have to use the formula

Then you have to solve x, and for that you have to use <span>RT/V
And to find total values:</span>

I am absolutely sure that this would be helpful for you.
The correct option is: ALL OF THE ABOVE.
A neutralization reaction is one in which acid and base react together in order to produce salt and water. The water formed is as a result of hydrogen ion and the hydroxyl ion which combine together to produce water. When a solution is neutralized, it implies that the salt is formed from equal weights of acid and base.
