<span>a) movement of heat through space </span>
I believe the answer is option D !!
Hello :)
I just took the quiz, so let me give you a step-by-step explanation of how I solved the problem. Disregard the 25 degrees, it is not needed to find the answer
pH + pOH = 14
4.48 (4.48 is the given pH in problem) + pOH = 14
4.48-4.48 + pOH = 14-4.48 (subtract 4.48 from 14)
pOH = 9.52 (letter c)
Hope this helped :)
Answer:
P(total) = 15 atm
Explanation:
Given data:
Pressure of O₂ = 5.75 atm
Pressure of N₂ = 7 atm
Pressure of He = 2.25 atm
Total pressure inside tank = ?
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) = P(O₂) + P(N₂) + P(He)
P(total) = 5.75 atm + 7 atm + 2.25 atm
P(total) = 15 atm
