  The  volume  occupied  by  0.118mol  of He  gas  at  a pressure of  1.05 atm  and  temperature  of  322k  is  calculated   by  use  of   ideal  gas    equation

that  is  PV = nRT
P(Pressure)1.05 atm
v(volume)=?
n  (number  of  moles)=0.118 mol
T(temperature)= 322K

from  equation  above volume(v)= nRT/p

volume(v) =  (0.118 mol  x  0.0821 L.atm/k.mol x322k)  / 1.05 atm =  2.97  L

Tom [10]

Methane was unusually high is the correct option. Hence, option B is correct.

<h3>What is methane?</h3>

Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent greenhouse gases. Its chemical formula is CH_4.

As the ice compacts over some time, tiny bubbles of the atmosphere or surroundings including greenhouse gases like carbon dioxide and methane—press inside the ice. These air pocket “fossils” give samples of what the atmosphere was kind when that layer of ice formed.

Based upon past studies and insights from current GHG levels, we assume that atmospheric levels of carbon dioxide and methane were unusually low.

What % of the ideal soil is air?​
alina1380 [7]

Answer:

In soil air as in the atmosphere, nitrogen gas (dinitrogen) comprises about 78%. In the atmosphere, oxygen comprises about 21% and carbon dioxide comprises about 0.36%. However, in the soil air, oxygen usually is replaced by carbon dioxide, so both range from about 0.4% to 21%.
