Considering the Dalton's law, the total pressure of the tank is 5.95 atm.
<h3>Dalton's law</h3>
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 present in the mixture.
This relationship is due to the assumption that there are no attractive forces between the gases.
<h3>Total pressure of the tank</h3>
A tank of gas has partial pressures of nitrogen and oxygen equal to 1.61 atm and 4.34 atm, respectively.
The total pressure of the tank is calculated as:
So, replacing the respective values:
Solving:
Finally, the total pressure of the tank is 5.95 atm.

Answer:
False
Explanation:
False : It is better they are closer together
The RF ( retention factor ) is calculated with this formula
= distance travelled / distance travelled by solvent
And the larger the RF factor of a compound the less polar the compound ( i.e. it will not stick to the stationary phase ) hence it is better the RF values of the components to be closer
<span>According to Faraday's Law,
W = I t e / F
Where,
W = Amount deposited = ?
I = Current = 3 A
t = Time = 965 s
e = Chemical equivalence = 52/3 = 17.33
F = Faraday's Constant = 96500
Putting Values,
W = (3 × 965 × 17.33) ÷ 96500
W = (50170.35) ÷ 96500
W = 0.52 g
As we know,
Moles = mass ÷ M.mass
Putting values,
Moles = 0.52 ÷ 52
Moles = 0.01</span>
