Look at sheet

Ight so like I'm too lazy to type this out just look at my work. Idk why it works I just know it works
The very common mineral shown in the figure that is referred in this problem that is commonly a pink- to cream-colored mineral with wavy, light-colored lines and does not effervesce would be feldspar. It make up about 41 percent weight of the Earth's crust. It is a group of rocks that contains tectosilicate compounds.
HF + NaOH = NaF + H2O
Aqueous sodium fluoride (NaF) and water are the products of the reaction between hydrofluoric acid (HF), a weak acid and sodium hydroxide (NaOH), a strong base.
It is a straightforward acid-base reaction, despite the fact that hydrogen fluoride is a weak acid that doesn't completely dissociate in water (the equilibrium between the dissociated & undissociated acid will however be pushed to the right as the reaction progresses and all of the acid will eventually be neutralized). Water and sodium fluoride are the products
What exactly is an acid-base reaction?
An acid-base reaction is a chemical reaction that occurs between the reactants, which are an acid and a base. This reaction produces salt and water as byproducts. An acid-base reaction is a double replacement reaction in which ions swap positions.

Answer:
C
electrons are negatively charged particles
1) If the hydrogen ion concentration of a solution is 10–10M, is the solution is definitely alkaline. The thing I used to determine that fact is basic point - <span>pH above 7 is always alkaine, and as a proof we can see from the task that </span><span>the concentration of hydroxyl OH- is pretty higher than hydrogen H+, which is a direct charachteristic of alkain solution.
Here is a tip for you, I bet it will be useful :
</span>>7 = basic
<span><7 = acidic </span>
7 = neutral
2) The most suitable answer for the second question is the negative logarithm of the hydrogen ion concentration. Pay attention to letters P and H, which pose as little promt as they point on Potential of Hydrogen. And the reason why it is negative is that scale of Ph is positive by default, but due to the fact that ion concentration is always less than 1, and as a result we get <span>the negative logarithm.
3) According to the small table shown in the first question, the answer is </span>[H+] = 1 x 10–11 M which is <span> pH 11, as I mentioned, since Ph is above 7 it is a basic solution.
</span>
