Answer:
P(total) = 978 mmHg
Explanation:
Given data:
Total pressure of gas = ?
Partial pressure of O₂ gas = 200 mmHg
Partial pressure of N₂ gas = 350 mmHg
Partial pressure of He gas = 428 mmHg
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
P(total) = P(O₂) + P(N₂) + P(He)
P(total) = 200 mmHg + 350 mmHg + 428 mmHg
P(total) = 978 mmHg
i know don't know the answerrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrr but just guessing is d. sodium
Because in SI, the expectation is that area and volume will be expressed in terms of a linear dimension( the metre) or its multiples.
A+2 B-3
A3B2 would be the answer to create a neutral compound
