423.3 mL of gas is at 49.2 C. It is compressed to a volume of 79 mL. What is the new temperture. Express your answer in Kelvin.
zzz [600]

Answer: 60.1K

Explanation:

Initial volume of gas V1 = 423.3mL

Initial temperature T1 = 49.2°C

Convert temperature in Celsius to Kelvin

( 49.2°C + 273 = 322.2K)

Final temperature T2 = ?

Final volume V2 = 79mL

According to Charle's law, the volume of a fixed mass of a gas is directly proportional to the temperature.

Mathematically, Charles' Law is expressed as: V1/T1 = V2/T2

423.3mL/322.2 = 79mL/T2

To get the value of T2, cross multiply

423.3mL x T2 = 322.2K x 79mL

423.3mL x T2 = 25453.8

T2 = (25453.8/423.3mL)

T2 = 60.1K

Thus, the new temperature of the gas is 60.1K

What are all the intermolecular forces present in a sample of BrF?
yuradex [85]

Answer:

dipole-dipole

Explanation:

Intermolecular forces exists between the molecules of a substance in a particular state of matter.

The type of intermolecular forces present in  a substance is determined by the electronegativity difference between the atoms that compose the substance.

There is a non zero electronegativity difference  between Br and F hence the molecule is polar and the intermolecular forces between the molecules of BrF are dipole-dipole forces.

The development of nuclear power has provided electricity for less money, but at a cost. What may be considered a "cost" of nucl
Schach [20]
D. A disadvantage of nuclear power is that waste products are unsafe and hard to store. They must be stored for many hundreds of years before they becomes safe and easier to dispose of, and we currently don't have a good method of storing them in the meantime.

If you have 8.943 L of carbon monoxide gas at SATP, how many moles would it contain?
viktelen [127]
1mole contains 22.4Lmol^-1
xmole contains 8.943
cross-multiply
x=1×8.943/22.4
x=0.40mole
there it contains 0.40moles.
