Answer from: rosieposie27

34.8 L of hydrogen gas

Explanation:

Now we have to use the ideal gas equation;

PV= nRT

P= pressure of the gas= 3.22atm

V= volume of the gas =

T= temperature of the gas = 45°C +273= 318K

n= number of moles =4.3 moles

R= universal gas constant= 0.082atm Lmol-1K-1

Making V the subject of the formula

V= nRT/P

V= 4.3×0.082×318/3.22

V= 34.8 L

Answer from: cody665

34.82 L

Explanation:

Step 1:

Data obtained from the question:

Number of mole (n) = 4.3 mole

Temperature (T) = 45°C = 45°C +273 = 318K

Pressure (P) = 3.22 atm

Volume (V) =?

Step 2:

Determination of the volume hydrogen gas.

With the application of the ideal gas equation, the volume of Hydrogen gas can be obtained as follow:

Note that the gas constant (R) = 0.082atm.L/Kmol

PV = nRT

3.22 x V = 4.3 x 0.082 x 318

Divide both side by 3.22

V = (4.3 x 0.082 x 318) /3.22

V = 34.82 L

Therefore the volume occupied by the hydrogen gas is 34.82 L

In meteorology, a cloud is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. nephology is the science of clouds, which is undertaken in the cloud physics branch of meteorology.cirrus clouds usually describe clouds high in the atmosphere that can include wispy clouds, typically with ice crystals. variations include cirrus, cirrocumulus and cirrostratus as defined by the cloud's position in the atmosphere.layered stratus clouds have both flat tops and bases, and can appear as if they take up the whole sky, stretching from horizon to horizon. other combinations and variations include stratus, stratocumulus, nimbostratus and altostratus.cumulus clouds often pile up in multiple layers of the atmosphere, representing clouds that develop vertically. cumulus clouds often look like pillars with anvil-type tops or columns of clouds stacked vertically. variations include cumulus, cumulus-congestus, cumulonimbus and altocumulus.

Benzonitrile (c6h5cn) is reduced to two different products depending on the reducing agent used. treatment with lithium aluminum hydride followed by water forms k, which has a molecular ion in its mass spectrum at 107 and the following ir absorptions: 3373, 3290, 3062, 2920, and 1600 cm-1. treatment with a milder reducing agent forms l, which has a molecular ion in its mass spectrum at 106 and the following ir absorptions: 3086, 2850, 2820, 2736, 1703, and 1600 cm-1. l shows fragments in its mass spectrum at m/z = 105 and 77. propose structures for k and l and choose an explanation for how this could be concluded.
