Explanation:
The given data is as follows.
T = 
= (11 + 273) K = 284 K, V = 45.0 L
m = 35 g
As molar mass of chlorine pentafluoride is 130.445 g/mol. Hence, number of moles of chlorine pentafluoride are as follows.
No. of moles = 
= 
= 0.268 mol
Now, using the ideal gas equation we will find the pressure as follows.
PV = nRT
P = 0.139 atm
Thus, we can conclude that pressure of chlorine pentafluoride gas in the given reaction vessel after the reaction is 0.139 atm.

Explanation:
The postulates of the kinetic theory of matter are;
- Every substance is made up of tiny particles called molecules. Brownian motion and diffusion illustrates this fact.
- The molecules that compose matter are in constant random motion.
- There exists an attractive force between the molecules in matter. The attractive forces between gases are negligible. Solids have a definite shape and volume due to a high magnitude of intermolecular forces. Liquids have a volume but no definite shape due to weaker intermolecular forces. Gases have the weakest intermolecular forces hence the do not have both a shape and volume. They take on the volume of the container into which they are put. This illustrates this fact.
- The actual volume occupied by gas molecules is negligible relative to the volume of the container. The fact that gases are easily compressible illustrates this fact.
- Temperature is a measure of the average kinetic energy of the molecules of a body.
Answer:
0.09 moles of Br₂
Explanation:
Bromine liquid it refers at Br₂ molecule which is liquid at room temperature.
Now to calculate the number of moles we use the following formula:
number of moles = mass (g) / molecular mass (g/mol)
For Br₂ molecule we have:
number of moles = 14.4 / 160 = 0.09 moles of Br₂
