Answer:
All statements are true
Explanation:
Arrhenius theory:-
The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.
According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, 
.
Hence, statement 1 is correct.
Bronsted-Lowry base is the specie which accepts the proton form the medium. For example, Benzoate ion is the conjugate base of the benzoic acid. It is a Bronsted-Lowry base and the dissociation of benzoate ion can be shown as:-
Hence, statement 2 is correct.
Acetic acid will dissociate as:-
Hence, statement 3 is also correct.
An acid-base reaction or a neutralization reaction is a <u>chemical reaction that occurs between an acid and a base producing a salt and water</u>. The acids and bases can be strong or weak depending on their degree of ionization in water.
Butyric acid is a weak acid and in water it is ionized in the following way, loosing a proton (H+):
HC4H7O2 (aq) ⇆ H+ (aq) + C4H7O2- (aq)
On the other hand, potassium hydroxide is a strong base, so it will be completely ionized in water:
KOH(aq) → K+(aq) + OH-(aq)
Then the <u>net acid-base reaction</u> between butyric acid and KOH is:
HC4H7O2 (aq) + OH- (aq) ⇆ H2O + C4H7O2- (aq)
It is valid to consider only the OH- produced from the ionization of KOH in water since, as mentioned, this molecule is completely ionized. Also, we do not include the K + in the net equation since it is a spectator ion, it does not undergo chemical changes.
The order of the students from the most reliable to the least reliable is C. Student 4, Student 1, Student 2, Student 3.
<h3>what student has the most reliable data?</h3><h3 />
the student with the most reliable data is the one that has the least variation in their data in the various trials.
this student is therefore student 4.
the next student would be student 1 and student 2 would be the third most reliable.
student 3 has large variations in their trials which makes their data the least reliable.
