A 9.0 mL sample of oxygen gas (Q) is stored at a pressure of 6.3 atm. If the pressure of the sample

Answer:

<h2>The answer is 23.63 mL</h2>

Explanation:

In order to find the new volume we use the formula for Boyle's law which is

$P_1V_1 = P_2V_2 \\$

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

$V_2 = \frac{P_1V_1}{P_2} \\$

From the question

P1 = 6.3 atm

V1 = 9 mL

P2 = 2.4 atm

So we have

$V_2 = \frac{6.3 \times 9}{2.4} \\ = 23.625$

We have the final answer as

<h3>23.63 mL</h3>

Hope this helps you

Answer:

$1s^{2}2s^{2}2p^{6}3s^{2}3p^{4}$

Explanation:

S is in 3d period, so it has 3 levels

1 level has 2 electrons, 2d level 8 electrons, 3d level 6 electrons

$1s^{2}2s^{2}2p^{6}3s^{2}3p^{4}$
