PH + pOH = 14
pH
= 14 - pOH
= 14 - 11
= 3
pH = 3
- lg [H+] = 3
[H+]
= 0.001

Answer:
Heat fusion
Explanation:
The energy required to change a solid to a liquid is called the heat of fusion.
Answer:
The most acidic solution had a pH of 3.27.
Explanation:
In order to solve this problem we need to keep in mind that the lower the pH of a solution is, the more acidic the solution is.
If among the pH readings across the measured breakfast drinks, the lowest one was 3.27 (as the problem tells us with the range), then that drink was the most acidic one.
Conversely, the least acidic one had a pH of 3.88.
Answer:
P(total) = 164 mmHg
Explanation:
Given data:
Partial pressure of helium = 77 mmHg
Partial pressure of nitrogen = 87 mmHg
Total pressure of flask = ?
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(He) + P(N₂)
P(total) = 77 mmHg + 87 mmHg
P(total) = 164 mmHg
