Why cam you calculate the total pressure of a mixture of gases by adding together the partial pressures of the component gases?

By applying Dalton's law of pressure equations we can calculate the total pressure of a mixture of gases by adding together the partial pressures of the component gases

Explanation:

Dalton's law of partial pressure is the concept used in calculating either partial pressure or total pressure in a given mixture of gases.

The law says that each gas has its own pressure which it puts on the mixture of gases. This pressure is called partial pressure. Also, the sum total of all the gases exerting pressure on the mixture is termed total pressure.

The quantity of individual gas can be known and hence it will get easy to calculate its  partial pressure.

The relation used is:

Partial pressure = mole fraction of the one gas from mixture x total pressure in the mixture.

It also says that total pressure is equal to:

total pressure = p1 +p2+p3pn

here p1, p2 is partial pressure of one of gases in mixture.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
