Explanation:
The given data is as follows.
mass of gasoline = 595.0 lb
volume of gasoline = 
As it is known that density is the amount of mass of a substance divided by its volume.
So, density of gasoline will be as follows.
Density = 
= 
= 42.5 
As, 1 lb = 0.4536 kg and 1 ft = 0.3048 m. Now, putting these values into the above equation (1) as follows.
Density = 42.5
= 
= 680.792 
= 680.8 (approx)
Density of water is 1000 . To measure specific gravity of gasoline, the formula will be as follows.
specific gravity of gasoline = 
= 
= 0.681
Thus, we can conclude that the specific gravity of gasoline is 0.681.
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.
I will state the electronegativities of each element.
Ca = 1.00
F = 3.98
H = 2.20
P = 2.19
Na = 0.93
The highest electronegative element is F (Fluorine).
False it's composed of 3 phosphate groups not phenol
