Resident 1 is to give the most valid results.
Answer:
The pH of a solution containing 0.1 mM H+ is 4
Explanation:
The pH of any solution is given by the following mathematical equation -
----------- Equation (A)
Where,
= the concentration of hydrogen ion in the solution.
Given
= 
Substituting the given value in equation (A) , we get -
![pH = -log[10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5B10%5E%7B-4%7D%5D)

Hence, The pH of a solution containing 0.1 mM H+ is 4
Answer:
Radioactive dating uses radioactive elements to date matter such as rocks and fossils. As the radioactive elements disintegrate, they turn into other elements. Scientist then use the ratio of the two elements to determine how old something is.
Explanation:
Hi!
The answer is C. The Sun
The energy that producers get from the sun, along with water, allows them to begin photosynthesis, the process in which they make their food, because they are not able to absorb other forms of energy because they are plants.
I hope this helps!!
