12.water can never dissapear as long as we keep digesting and drinking water
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.

For option C it is 1
Explanation:
For checking the spontaneity of a reaction, we have to check the sign of ΔG using the below formula
<h3>ΔG = ΔH - T×ΔS</h3>
where
ΔG is the change in Gibbs free energy
ΔH is the change in enthalpy
T is the temperature
ΔS is the change in entropy
<h3>For spontaneous reactions, ΔG must be less than zero and for non-spontaneous reactions ΔG must be greater than zero but for an equilibrium reaction ΔG must be equal to zero</h3>
So in case of 1 as ΔH and ΔS are positive if the temperature is above a certain value then ΔG will be less than zero
So in case of 2 as ΔH is negative and ΔS is positive then ΔG will always be less than zero at all temperatures
So in case of 3 as ΔH and ΔS are negative if the temperature is below a certain value then ΔG will be less than zero
So in case of 4 as ΔH is positive and ΔS is negative then ΔG will always be greater than zero but in reverse direction as ΔG is less than zero therefore in reverse direction the reaction will be spontaneous at all temperatures
