Filtration: To remove solid substance from liquid.
Evaporation: To remove dissolved substance from liquid.
Distillation: To separate 2 liquids with different boiling points.
Answer: The moles of carbon needed will be, 13.8 moles
Explanation: Moles of = 5.52 mole
Now we have to calculate to moles of carbon.
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 2 mole of react to give 5 moles of carbon
So, 5.52 mole of react to give moles of carbon
Therefore, the moles of carbon needed will be, 13.8 moles
Considering the Dalton's partial pressure, the total pressure in the mixture of gases is 1.371 atm.
The pressure exerted by a particular gas in a mixture is known as its partial pressure.
So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:
= 
where n is the amount of gases in the mixture.
Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture. So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:
= 
In this case, the partial pressure of gas H₂ can be expressed as:
= 
You know:
= 0.48 atm
= 0.35
Replacing in the definition of partial pressure of gas H₂:

Solving:
= 
= 1.371 atm
In summary, the total pressure in the mixture of gases is 1.371 atm.

It's a chemical change beacause elements are combining to make something new! :)
Compounds that are gases at room temperature are covalent bonds (nonmetal + nonmetal).
