6.At a pressure of 5.0 atmospheres, a sample of gas occupies 40 liters. What volume will the same sample occupy at 1.0 atmosphere?
(a) 50 L
(b) 100 L
O (C) 80 L
(d) 200 L

Explanation:

The new volume can be found by using the formula for Boyle's law which is

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the new volume

So we have

We have the final answer as

Hope this helps you

a is the answer to this question

explanation:

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
