N a system for separating gases a tank containing a mixture of hydrogen and carbon dioxide is connected to a much larger tank where the pressure is kept very low. The two tanks are separated by a porous membrane through which the molecules must effuse. If the initial partial pressures of each gas is 5.00 atm, what will be the mole fraction of hydrogen in the tank after the partial pressure of carbon dioxide has declined to 4.50 atm

The mol fraction of the hydrogen gas = 0.526

Explanation:

Step 1: data given

mixture of hydrogen and carbon dioxide

the initial partial pressures of each gas is 5.00 atm

the partial pressure of carbon dioxide has declined to 4.50 atm

Step 2: Calculate total pressure

Total pressure = 4.5 atm + 5.0 atm

Total pressure = 9.5 atm

Step 3: Calculate mol fraction

Partial pressure = mole fraction * total pressure

Mol fraction = partial pressure / total pressure

Mol fraction carbon dioxide = 4.5 atm / 9.5 atm

Mol fraction carbon dioxide =  0.474

Mol fraction of hydrogen = 1 - 0.474 = 0.526

The mol fraction of the hydrogen gas = 0.526

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
