a 75.0 liter canister contains 15.82 moles of argon at a pressure of 546.8 kilopascals. What is the temperature of the canister?
abruzzese [7]

Pressure of argon = 546.8 kPa

Conversion factor: 1 atm = 101.325 kPa

Pressure of argon = 546.8 kPa x 1 atm/101.325 kPa = 5.4 atm

Moles of argon = 15.82

Volume of argon = 75.0 L

According to Ideal gas law,

PV = nRT

where P is the pressure, V is the volume , n is the number of moles, R is the universal gas constant, and T is the temperature

T = PV/nR = (5.4 atm x 75.0 L) / (15.82 x 0.0821 L.atm.mol⁻¹K⁻¹)

T = 311.82 K

Hence the temperature of the canister is 311.82 K.

A postulate of the kinetic molecular theory is listed.
timofeeve [1]

1) Recording the change in pressure when heating an inflated tire

Explanation:

This happens because with an increase in temperatures, the kinetic energy of the gas in the tire increases. The increase in kinetic energy means the molecules move more rapidly. There is an increased rate of collisions between the gas molecules, and increased energy of the collisions, and between the gas molecules and inner walls of the tire hence the increased pressure. Pressure and temperatures and directly proportional s long as the volume of the gas is kept constant.

What is the net ionic equation for the reaction that occurs when aqueous solutions of naoh and hno3 are mixed?
likoan [24]

Answer:-

H+ + OH- --> H2O

Explanation:-

The chemical equation is NaOH + HNO3 --> NaNO3 + H2O

Now for the ionic compounds

HNO3 --> H+ + NO3 -

NaOH--> Na+ + OH-

NaNO3 --> Na+ + NO3-

Water being covalent will remain as H2O,

Hence

HNO3 + NaOH--> NaNO3 + H2O

H+ + NO3 - + Na+ + OH- --> Na+ + No3 - + H2O.

Crossing out common terms

H+ + OH- --> H2O
