Because there is less of it available.
Answer:
PN₂ = 191.3 Kpa
Explanation:
Given data:
Total pressure of tire = 245.0 Kpa
Partial pressure of PO₂ = 51.3 Kpa
Partial pressure of PCO₂ = 0.10 Kpa
Partial pressure of others = 2.3 Kpa
Partial pressure of PN₂ = ?
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = PO₂ + PCO₂ + P(others)+ PN₂
245 Kpa = 51.3 Kpa + 0.10 Kpa + 2.3 Kpa + PN₂
245 Kpa = 53.7 Kpa+ PN₂
PN₂ = 245 Kpa - 53.7 Kpa
PN₂ = 191.3 Kpa
2.5 x 10^24 molecules of C4H10
The compound sodium sulfate is made of sodium ion and sulfate ion.
The formula can be written as Na₂SO₄.
The cation present in this compound is Na⁺ and the anion is SO₄²⁻.
The compound barium sulfate is made of barium ion and sulfate ion.
The formula can be written as BaSO₄.
This compound contains the cation Ba²⁺ and anion SO₄²⁻.
From the above , we can see that both the compounds have common anion which SO₄²⁻
So, the sulfate, SO₄²⁻ is the common ion when sodium sulfate is added to a solution of barium sulfate
