A gas that has a volume of 28 liters, a temperature of 45C, And an unknown pressure has its volume increased to 34 liters and it
patriot [66]

Answer:

P1 = 2.5ATM

Explanation:

V1 = 28L

T1 = 45°C = (45 + 273.15)K = 318.15K

V2 = 34L

T2 = 35°C = (35 + 273.15)K = 308.15K

P1 = ?

P2 = 2ATM

applying combined gas equation,

P1V1 / T1 = P2V2 / T2

P1*V1*T2 = P2*V2*T1

Solving for P1

P1 = P2*V2*T1 / V1*T2

P1 = (2.0 * 34 * 318.15) / (28 * 308.15)

P1 = 21634.2 / 8628.2

P1 = 2.5ATM

The initial pressure was 2.5ATM

The air in a bicycle tire is bubbled through water and collected at 25 ∘C. If the total volume of gas collected is 5.30 L at a t
Klio2033 [76]

<u>Answer:</u> The number of moles of gas in bicycle tire is 0.210 moles

<u>Explanation:</u>

To calculate the moles of gas, we use the equation given by ideal gas which follows:

PV=nRT

where,

P = pressure of the gas = 737 torr

V = Volume of the gas = 5.30 L

T = Temperature of the gas = 25^oC=[25+273]K=298K

R = Gas constant = 62.364\text{ L. Torr }mol^{-1}K^{-1}

n = number of moles of gas = ?

Putting values in above equation, we get:

737Torr\times 5.30L=n\times 62.364\text{ L Torr }mol^{-1}K^{-1}\times 298K\\\\n=\frac{737\times 5.30}{62.364\times 298}=0.210mol

Hence, the number of moles of gas in bicycle tire is 0.210 moles

What rule/principle States that electrons fill orbital from lowest energy to highest energy?
Flauer [41]
The aufbau principle, from the German Aufbauprinzip (building-up principle), also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.
