A Helium gas in a tube with a volume of 9.583 L under pressure of 4.972 atm at 31.8 c
andre [41]

1.905 moles of Helium gas are in the tube. Hence, option A is correct.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Calculate the moles of the gas using the gas law,

PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.

Given data:

P= 4.972 atm

V= 9.583 L

n=?

R= 0.082057338 \;L \;atm \;K^{-1}mol^{-1}

T=31.8 +273= 304.8 K

Putting value in the given equation:

\frac{PV}{RT}=n

n= \frac{4.972 \;atm\; X \;9.583 \;L}{0.082057338 \;L \;atm \;K^{-1}mol^{-1} X 304.8}

Moles = 1.905 moles

1.905 moles of Helium gas are in the tube. Hence, option A is correct.

When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.
almond37 [142]

True

Explanation:

When people conserve electricity, power plants do not need to produce as much electricity because there is less demand for it.

This very correct.

  • When electricity is used in a sustainable way, there is little of it consumed.
  • Switching off idle electronics would make that amount of electric current to be re-distributed to another place.
  • Less coal and fuel would be used and power plants do not need to produce as much electricity.
  • Most electricity produced in power plants are often wasted due to idle appliances consuming the bulk of them.
  • When these appliances are turned off, less energy is in demand and less will be produced.
