A gas at 1.00 atm occupies 5.00 Liters what would the pressure be with the volume at 10.00 L I’d f the temperature remains const
soldier1979 [14.2K]

Answer:

0.5 atm

Explanation:

Data obtained from the question include:

P1 (initial pressure) = 1 atm

V1 (initial volume) = 5L

V2 (final volume) = 10L

P2 (final pressure) =?

The gas is obeying Boyle's law since the temperature is constant.

Using the Boyle's law equation P1V1 = P2V2, the final pressure can be obtained as follow:

P1V1 = P2V2

1 x 5 = P2 x 10

Divide both side by 10

P2 = (1 x 5)/10

P2 = 0.5 atm

Therefore, the pressure is 0.5 atm

What mass of neon gas is required to fill a 5.00-L container to<br> a pressure of 1.02 atm at 25 °C?
sweet [91]

Answer:

m=4.21g

Explanation:

Hello,

In this case, by using the ideal gas equation:

PV=nRT

We can compute the mass of neon gas at the given conditions by firstly computing the moles and also considering the temperature in kelvins (298K):

n=\frac{PV}{RT}=\frac{1.02atm*5.00L}{0.082\frac{atm*L}{mol*K}*298K}\\  \\n=0.209mol

Finally, by using the atomic mass of neon gas (20.18g/mol) we compute the required mass to fill the 5.00-L container:

m=0.209mol*\frac{20.18g}{1mol}\\ \\m=4.21g

Best regards.

2. Which element below would be the best choice when creating a covalent molecule with an
sammy [17]

Answer:

The chemical elements most likely to form covalent bonds are those that share electrons, such as carbon, as opposed to those that take them from another element to form an ionic bond. In general, they are nonmetals with similar electronegativities.
