12.70 L of a gas has a pressure of 0.63 atm. What is the volume of the gas at 105kPa?
Zielflug [23.3K]

Answer: 7.693 L

Explanation:

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly 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:

P_1=0.63atm\\V_1=12.70L\\P_2=105kPa=1.04atm(1kPa=0.009atm)\\V_2=?

Putting values in above equation, we get:

0.63\times 12.70mL=1.04\times V_2\\\\V_2=7.693L

Thus new volume of the gas is 7.693 L

lidiya [134]

Answer:

Strength

Explanation:

Lattice energy is the energy needed to remove one mole of ionic substance to its gaseous ion.

The lattice energy is used to determine the strength of a substance.

  • Lattice energy increases as the size of an ion decreases.
  • It decreases as the ion size increases.
  • This quantity is often determined using electrostatics method in the laboratory
  • The lattice energy is used to break an ionic solid to form a gaseous compound.
