Answer:

Explanation:

Nobel gasses are not reactive and are the far right group on the periodic table. This is because they have a full valence electron shell which is the most stable electron configuration. Most reactions occur in order for an atom to fill its valence shell and since they already have a full valence shell there is no reason for them to react.

In an airplane, a gas sample occurs at a volume of 1.5 L at 760.0 torr. Suppose, while flying, the airplane loses pressure and t

jekas [21]

Answer:

100 torr

Explanation:

First find the formula you need to use, this will be...

P2 = V1 x P1 / V2

Next, fill in the numbers, this will be...

P2 = ? (we are trying to find this)

P1 = 760 torr

V1 = 1.5 L

V2 = 11.4 L

Next, turn into new formula (just rearrange)

P2 = 1.5 L x 760 torr / 11.4 L

Next, do the math. This should get you...

<u>100 torr</u> as your answer
