Answer:
![[H^+]=1.78x10^{-8}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D1.78x10%5E%7B-8%7DM)
Explanation:
Hello there!
In this case, according to the given information about the pH, it is firstly necessary for us to remember that the pH is defined as the potential of the hydrogen ions in the solution and the concentration of those ions represents how many of them are present in the solution; in such a way, it is possible for us use:
![pH=-log([H^+])](https://tex.z-dn.net/?f=pH%3D-log%28%5BH%5E%2B%5D%29)
Whereas the concentration of hydrogen ions can be calculated as follows:
![[H^+]=10^{-pH}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-pH%7D)
So we plug in the given pH to obtain:
![[H^+]=10^{-7.75}=1.78x10^{-8}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-7.75%7D%3D1.78x10%5E%7B-8%7DM)

Answer:
The thermic effect of food.
Explanation:
The process in which metabolic rate increase after meal is called the THERMIC EFFECT OF FOOD.
THERMICAL EFFECT OF FOOD can be defined as the way in which some calories a person or an individual consumed after meal help to break down the food for easy absorbing and to store the food consumed while some are burn off during execise which is why a person or an individual metabolic rate may elevate after meal, during exercise or due to some other factors reason been that human body makes use of energy everyday due to day to day activities.
Example a person who consumed a protein food may experience high THERMIC EFFECT than the person who consumed food that contained fat or carbohydrates reason been it can take a long time for such person body to break down the food, burn and absorb the protein.
Therefore The increase in metabolic rate after a meal is called THERMIC EFFECT OF FOOD.
If the temperature becomes colder
Mostly in my opinion I think it’s the secound one
