<u>Answer:</u> There is no predicate adjective in the sentence.
<u>Explanation:</u>
Predicate adjective is defined as an adjective that follows the linking verb and modifies the subject of the linking verb.
For Example:
The shoes look expensive.
In this sentence, the shoes are the subject, 'look' is the linking verb and 'expensive' is the predicate adjective.
The predicate adjective modified the subject.
In the given sentence,
'Five' is a common noun, 'cookies' is the subject, 'are' is the helping verb, 'on' is the preposition, 'the' is an article and 'table' is a countable noun.
Hence, there is no linking verb and therefore, this sentence has no predicate adjective.
Answer:
<u>B</u>
Explanation:
An Arrhenius Acid is a substance that dissociates in water to form Hydrogen (H⁺) ions.
Let's write the dissociation reactions of each of the options :
⇒ KF = K⁺ + F⁻
⇒ HF = H⁺ + F⁻
⇒ KOH = K⁺ + OH⁻
⇒ LiH = Li⁺ + H⁻
Only HF forms a Hydrogen ion on dissociation, hence it is the Arrhenius Acid.
