<em>The concentration, mobility, and valence state of the ionized species in a solution, as well as the temperature at which the measurement is done, all have a role. The conductivity of water increases with the concentration of ions in it.</em>
The pH shows the degree of acidity of alkalinity of a solution. The pH of the HF can be obtained from the ICE table.
<h3>What is pH?</h3>
The term pH refers to the hydrogen ion concentration of a solution. Recall that acids produce hydrogen or oxonium ion in solution.
The first step to determine the pH of the HF solution is to set up the ICE table as shown;
HF + H2O ⇄ H3O^+ + F^-
I
C
E
The values of the initial concentration of HF as well as the Ka of HF are not given. If these two values are give, the pH can be obtained from;
Ka = [H3O^+] [ F^-]/[HF] Knowing that [H3O^+] = [ F^-] = x

The coordinates of p without using any new variables are; (a, b).
<h3>Finding Rectangle Coordinates</h3>
From the properties of a rectangle, we know that;
- each of its angle is a right angle.
- each side of the rectangle is perpendicular to its adjacent side.
- the distance of a point from a line is the length of the perpendicular drawn from the point to the line.
From the rectangle image attached, we can see that;
Point P is at a distance of b units from x-axis and a units from y-axis.
Thus, the coordinates of Point P is (a, b)

Answer:
20000*(1+15%)³=30417.5
Explanation:
The number $40000 is irrelevant. Don't be disturbed!
This is a typical compound interest question. Use the compound interest formula: S=p(1+<em>i)ⁿ</em>
S for sum, p for principal balance, <em>i </em>for interest rate, n for the number of years or times
Answer:
None of them
Explanation:
because there is no graph hence nothing can be done
