Fluoride ion (F⁻) can act as a base by accepting a proton (H⁺) to form hydrogen fluoride (HF).
What is chemical reaction?Breaking chemical bonds between reactant molecules (particles) and creating new bonds between atoms in product particles are two aspects of chemical reactions (molecules).
While there are the same number of atoms both before and after the chemical transition, there will be a change in the number of molecules.
The chemical equation for this reaction can be written as:
F⁻(aq) + H⁺(aq) → HF(aq)
In this equation, "aq" represents the aqueous phase, indicating that the species are dissolved in water.
The fluoride ion acts as a base by accepting a proton (H⁺) from the acid (which acts as an acid) and forming the weak acid, hydrogen fluoride (HF).
Thus, this is the equation that shows the way in which the anion acts as a base.

What is the Arithmetic Sequence?We are going to use the arithmetic sequence formula since we require the previous term in a sequence.
The arithmetic sequence formula is;
aₙ = a + (n − 1)d,
where;
a is the first term of the sequence
n is the position of the term in the sequence
d is the common difference
aₙ is the nth term of the sequence.
Our sequence is 10, 14, 18, 22 up to row 20.
Using the sequence formula;
a_20 = 10 + (20 − 1)4.
a_20 = 10 + (19* 4)
a_20 = 10 + 76
a_20 = 86.
Thus, the number of seats in row 20 was 86 seats.

The electrolysis of molten alcl3 for 4. 25 hr with an electrical current of 25. 0 a produces ________ g of aluminum metal
The electrolysis of molten AlCl3 for 4.25 hr having the current of 25Ampere will produces 35.67g of aluminum metal.
What is Electrolysis?Electrolysis can be described as the process where by electric current is passed through a substance to effect a chemical change.
The mass of the deposited metal can be calculated as
=[tex]W = CEt/96500[/tex]
Given;
t = time taken = 4.25hr
we can convert the time given from ( hrs) to secs as follows;
60secs=1 mins
60*60 secs = 1 hr
Then 25hrs= 4.25*60*60 = 15300s
C = Current = 25.0 A
E = Equivalent mass of Aluminum =9
Atomic-mass/valency = 27/3 = 9
If we substitute the values we have;
[tex]W = ( 27*9*15300)/96500[/tex]

An experiment was conducted to determine whether the price of a golf club affected the distance a golfer could hit a golf ball. A sample of 60 golfers were randomly assigned to one of two groups, c or e. The 30 golfers in group c were given a club and told the price of the club was cheap; the 30 golfers in group e were given the same club and told the price of the club was expensive. In reality, there was no difference in price. The golfers used their assigned clubs to hit a golf ball as far as they could. The distance, in yards, that each golfer hit the golf ball was recorded, and the mean distance calculated for each group. A two-sample t-test for a difference in means will be conducted
