Answer:
b. 1.5 atm.
Explanation:
Hello!
In this case, since the undergoing chemical reaction suggests that two moles of A react with one moles of B to produce two moles of C, for the final pressure we can write:
Now, if we introduce the stoichiometry, and the change in the pressure 
we can write:
Nevertheless, since the reaction goes to completion, all A is consumed and there is a leftover of B, and that consumed A is:
Thus, the final pressure is:
Therefore the answer is b. 1.5 atm.
Best regards!
It would get the news out about Orbit White, and people would hear about it, and/or see the advert. They might even want to buy it or go into the grocery store thinking about it and end up buying it.
I hope I didn't misread the question because this looks more like an English/ Social Studies question than a chemistry question.

Explanation:
6 electrons... 's' can hold 2..... 'd' can hold 10 and 'f' can hold 14
The graduated cylinder is used to measure the volume of KOH and H2SO4 when accurate volume measurement is not required.
In the laboratory certain graduated apparatus are used to measure liquids. These graduated apparatus used to measure liquids include;
- burette
- pipette
- measuring cylinder
- Erlenmeyer flask
Sometimes, we are not really looking for a strictly accurate volume of liquid and we can use a graduated cylinder to measure the volume of liquid in such cases.
However, when we need to have strictly accurate volume measurement, we need a pipet or a buret.
