Answer:

Explanation:
Hello.
In this case, we can solve this problem by applying the Boyle's law which allows us to understand the pressure-volume behavior as a directly proportional relationship:

In such away, knowing the both the initial pressure and volume and the final volume, we can compute the final pressure as shown below:

Consider that the given initial pressure is also equal to Pa:

Which stands for a pressure increase when volume decreases.

Answer:
Propenyl-benzene
Explanation:
Hello,
Elimination reaction of solid (1-chloropropyl)-benzene due to the heat in presence of ethanol turns out based on the attached picture in which both the chlorine a the hydrogen in the second carbon go out and subsequently get together to form propenyl-benzene and hydrochloric acid.
Best regards.
