How many moles of propane (C3H8) are in a 7.00-L tank at 20.0°C and 5.45 atm of pressure?

1 answer:

7 0

By the claperyron equation<span>:

T = 20.0ºC + 273.15 => 293.15 K

R = 0.082 atm

Therefore:

P x V = n x R x T

5.45 x 7.00 = n x 0.082 x 293.15

38.15 = n x 24.0383

n = 38.15 / 24.0383

n = 1.587 moles of C3H8

If the pressure of a gas sample is quadrupled and the absolute temperature is doubled, by what factor does the volume of the sam

Natasha_Volkova [10]

Answer:

D) 1/2

Explanation:

Using Ideal gas equation for same mole of gas as

$\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}$

Given,

P₂ = 4P₁

T₂ = 2T₁

Using above equation as:

$\frac {{P_1}\times {V_1}}{T_1}=\frac {{P_2}\times {V_2}}{T_2}$

$\frac {{P_1}\times {V_1}}{T_1}=\frac {{4\times P_1}\times {V_2}}{2\times T_1}$

$V_2=\frac{1}{2}\times V_1$

<u>The volume change by half of the original.</u>

The enthalpy of combustion for octane (C8H18(l)), a key component of gasoline, is -5,074 kJ/mol. This value is the Delta. Hrxn f

Inessa [10]

Combustion can be defined as the reaction of a compound with oxygen. The enthalpy of combustion of octane is $\Delta H_{\rm rxn}$ for $\rm C_8H_{18}\;+\;25\;O_2\;\rightarrow 8\;CO_2\;+\;9\;H_2O$ .

<h3>What is the enthalpy of reaction?</h3>

The enthalpy of reaction is the amount of heat energy absorbed or lost by the molecules in the chemical reaction.

The enthalpy of combustion is the amount of heat energy released by the compound in the reaction with oxygen.

The reaction in which heat is liberated with the reaction of a compound with oxygen has an enthalpy of combustion, equivalent to the enthalpy of reaction.

The combustion of octane can be given as:

$\rm C_8H_{18}\;+\;25\;O_2\;\rightarrow 8\;CO_2\;+\;9\;H_2O$

Thus, the reaction has combustion energy equivalent to the enthalpy of the reaction is $\rm C_8H_{18}\;+\;25\;O_2\;\rightarrow 8\;CO_2\;+\;9\;H_2O$ . Thus, option B is correct.

Air pressure is lowest in the lungs during whi h of the following points during inspiration or expiration

AlladinOne [14]

Answer:

Inspiration

Explanation:

This question is on application of Boyle's law; <u>pressure is inversely proportional to volume</u>.when we inhale air, the diaphragm and the muscles in the ribs contract thus increasing the volume in the lungs.Increased volume of the lungs cause the pressure to decrease.During exhaling, the diaphragm and muscles in the ribs relax, making the lungs to recoil and reduce in volume to force air out.Pressure in the lungs is increased than that in the environment making air to move out.

What is the H+ concentration when pH is 2, 6, 7, 8, and 12?

Mariulka [41]

Answer:

See below.

Explanation:

pH = - log (H+)

So the pH of 1 x 10^-7 M solution is 7.

I'm sorry but I'm not sure about what the other units mean, so Im not sure of the answer to those.

If you convert the other units to the form 1 x 10^-n then the pH will be n.
