(Boyle's Law):

elena-s [515]

Answer: The final volume will be 16.85 mL

Explanation:

To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

The equation given by this law is:

$P_1V_1=P_2V_2$

where,

$P_1\text{ and }V_1$ are initial pressure and volume.

$P_2\text{ and }V_2$ are final pressure and volume.

We are given:

Conversion factor: 1 atm = 760 torr

$P_1=705torr=0.927atm\\V_1=50mL\\P_2=2.75atm\\V_2=?mL$

Putting values in above equation, we get:

$0.927atm\times 50mL=2.75atm\times V_2\\\\V_2=16.85mL$

Hence, the final volume will be 16.85 mL

Geef de systematische naam van P2S3

Tresset [83]

The question is: Give the systematic name of $P_{2}S_{3}$ .

Answer: The systematic name of $P_{2}S_{3}$ is diphosphorus trisulfide.

Explanation:

As the chemical formula of given compound is $P_{2}S_{3}$ . This sows that there are two phosphorus atoms so a prefix "di" will be added before the name of phosphorus atom.

Whereas there are three sulfur atoms present here. So, a prefix "tri" will be added before naming the sulfur atom. As sulfur is the anion so a suffix '-ide' will be added to its name.

Hence, name of the compound $P_{2}S_{3}$ is diphosphorus trisulfide.

Thus, we can conclude that the systematic name of $P_{2}S_{3}$ is diphosphorus trisulfide.
