Answer:
Clavulanic acid has two (2) chiral centers.
Explanation:
A chiral center is a center (usually carbon) with four different substituents.
The structure of clavulanic acid is shown in the attachment below.
Consider the labeled diagram in the attachment,
Carbon A is not a chiral carbon because it has two hydrogen atoms attached to it
Carbon B is not a chiral carbon because it has only three substituents
Carbon C is a chiral carbon because it has four different substituents
Carbon D is a chiral carbon because it has four different substituents
Carbon E is not a chiral carbon because it has only three atoms directly attached to it
Carbon F is not a chiral carbon because it has only three atoms directly attached to it
Carbon G is not a chiral carbon because it has two hydrogen atoms attached to it
Carbon H is not a chiral carbon because it has only three substituents
Then, only carbons C and D are chiral carbons.
Hence, clavulanic acid have two (2) chiral centers.
Answer: The statement it is a weak acid is true for the substance.
Explanation:
An acid that dissociates completely when dissolved in water to give hydrogen
or hydronium
ions is called a strong acid.
For example, HCl is a strong acid.

An acid that dissociates partially or weakly when dissolved in water to given hydrogen or hydronium ions is called a weak acid.
For example,
is a weak acid.

A strong base is a base which when dissolved in water then it dissociates completely to give hydroxide ions.
For example, NaOH is a strong acid.
A weak base is a base which when dissolved in water then it dissociates partially or weakly to give hydroxide ions.
For example,
is a weak base.
Hence, in an aqueous solution where 42% of a substance dissociates to release hydronium ions shows that the dissociation is less than 50%. This means that substance is dissociating weakly so, it is a weak acid.
Thus, we can conclude that the statement it is a weak acid is true for the substance.
