Schrodinger developed a famous equation that allows the solutions for electron wave functions to be found given a specific potential. For the case of an atom, Schroginger's equation allows the determination of electron wave functions. These wave functions tell us how electrons are distributed in space around the atom.
PH scale is used to determine how acidic or basic a solution is.
pH can be calculated as follows;
by knowing the ph we can calculate pOH
pH + pOH = 14
pOH = 14 - 8.1
pOH = 5.9
pOH is used to calculate the hydroxide ion concentration
pOH = -log[OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = 1.26 x 10⁻⁶ M
therefore hydroxide ion concentration is 1.26 x 10⁻⁶ M
is most abundant and 6310 times more than HF.
<h3>What is a strong and weak acid?</h3>
When an acid is dissolved in water, all of its molecules disintegrate, making the acid powerful.
When an acid is dissolved in water, only a small number of its molecules disintegrate, making the acid weak. Strong acids have a lower pH than weak acids.
The powerful acids include perchloric acid, chloric acid, nitric acid, sulfuric acid, hydrobromic acid, and hydroiodic acid.
Given:
Pka=3..2
pH=7
Let the volume be 1 liter
[HF]=01 M
Now,
F-:HF= 6309.57:1
Therefore, the most abundant is and has 6310 times more than HF is .

Answer:
453.592 grams
Explanation:
Given
Mass = 1 lb
Required.
Convert to grams using dimensional analysis
Represent 1 lb with x g
In unit conversion, we have that.
1 lb = 453.592 g
So:
Getting the equivalent of lb in g, we have:
x g = 1 lb * (453.592 g/ 1 lb)
x g = 1 * 453.592 g
x g = 453.592 grams
Hence:
The equivalent of 1 lb in grams is 453.592 grams
