True or false:

In chemistry and physics, Dalton's law (also called Dalton's law of partial pressures) states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.

Answer:

True.

Step-by-step explanation:

According to Dalton law of partial pressure,

The total pressure exerted by mixture of gas is equal to the sum of the partial pressure of individual gases.

Mathematical expression:

P(total) = P₁ + P₂ + .............P(n)

P₁= Partial pressure of one gas

P₂ = Partial pressure of second gas

Pn = Partial pressure of number of gases

For example:

A gaseous mixture consist of He and Ne gas . The pressure exerted by He is 2 atm while neon exerted 4 atm. The total pressure will be:

P(total) = P(He) + P(Ne)

P(total) = 2 atm + 4 atm

P(total) = 6 atm
