The correct option is COVALENT BONDS.
A Lewis acid is defined as a substance which accept a pair of electron while a Lewis base refers to a substance that donate an unshared pair of electrons to another chemical specie with which it shared the donated pair of electrons.
Lewis acid and Lewis base react together to form salt and water. This type of reaction is called neutralization reaction. The neutralization reaction of Lewis acid and Lewis base involves electron pairs transfer, thus, there is an increase in the number of covalent bonds during this reaction.

Answer:
74.0 mL
Explanation:
In the equivalence point we have:
Where:
is the number of moles of the acid
is the number of moles of the base
Where M is the concentration and V is the volume
Hence the volume of the base is:
Therefore, is needed 74.0 mL of the potassium hydroxide solution to reach the equivalence point.
I hope it helps you!
Answer: p2 = 1.06p1
Explanation: pressure increases with temperature increase.
According to Gass law
P1/T1 = P2/T2
T1 = 20°c = 20 +273 = 293k
T2 = 40°c = 40 +373 = 313k
Therefore
P2 = P1T2/T1 = 313P2/293
P2 = 1.06P1
