A gas has a volume of 240mL at 700mmHg pressure. What pressure is needed to reduce the volume to 80mL?

Chemistry
1 answer:
Dovator [93]3 years ago
5 0

Answer:

<h3>The answer is 2100 mmHg</h3>

Explanation:

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

P_1V_1 = P_2V_2

Since we are finding the new pressure

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

From the question we have

P_2 =  \frac{240 \times 700}{80}  =  \frac{168000}{80}  =  \frac{16800}{8}  \\

We have the final answer as

<h3>2100 mmHg</h3>

Hope this helps you

Why is phosphorus unusual compared to other group 15 elements? Select the correct answer below: A. There are compounds that cont
luda_lava [24]

Answer:

There are compounds that contain phosphorus-phosphorus bonds with uncommon oxidation states.

Explanation:

Phosphorus is a member of group 15 in the periodic table. Its common oxidation States are -3 and +5. Phosphorus is believed to firm some of its compounds by the participation of hybridized d-orbitals in bonding although this is also disputed by some scientists owing to the high energy of d - orbitals.

Phosphorus form compounds having phosphorus-phosphorus bonds in unusual oxidation states such as diphosphorus tetrahydride, H2P-PH2, and tetraphosphorus trisulfide, P4S hence the answer.
