Answer:
The total pressure exerted by mixture of gas is equal to the sum of the partial pressure of individual gases.
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
Answer: 2 mol of NaOH
Explanation:
The balanced chemical equation for the reaction is:
Na2O + H2O --> 2NaOH
Looking at this, we can see that 1 mol of Na2O will react with 1 mol of H2O to produce 2 mol of NaOH
Antimony,carbon sodium gallium
Answer: You can calculate the pH of an acid or base solution given the hydronium ion concentration by using the formula pH = -log [H3O+] or if given the hydroxide ion concentration by the formula [H3O+] = Kw / [OH-], then using the pH = -log [H3O+] formula.
