600. ml of a gas at 50.0 kPa is compressed, at constant temperature, until its volume becomes 200. ml. What is the new pressure

Flura [38]

Answer:

<h3>The answer is 150 kPa</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

$P_2 = \frac{600 \times 50000}{200} = \frac{30000000}{200} \\ = 150000$

We have the final answer as

Hope this helps you

A process stream contains 450 mol/s benzene and 375 mol/s toluene. Calculate the mole fraction of benzene in the process stream.

Tema [17]

Answer:

0.5455

Explanation:

The moles of benzene in the process stream in 1 sec = 450 moles

The moles of toluene in the process stream in 1 sec = 375 moles

So, according to definition of mole fraction:

$Mole\ fraction\ of\ benzene=\frac {n_{benzene}}{n_{benzene}+n_{toluene}}$

Applying values as:

$Mole\ fraction\ of\ benzene=\frac {450}{450+375}$

<u>Mole fraction of benzene in the process stream = 0.5455</u>

A thick coating of plaster of Paris is applied over the bandage on a fracture bone.It becomes hard on drying to keep the fractur

seraphim [82]

Answer:

The change in POP can not be reversed hence it is a chemical change.

Explanation:

Plaster of Paris (POP) is used to immobilize a fractured bone. The POP sets when water is added to it, it hardens irreversibly. Once it hardens, its shape can not be changed by any physical means. This means that the hardening of POP is a chemical change.

The chemical name of plaster of Paris is calcium sulfate hemihydrate. The setting of POP is an example of a chemical reaction.
