Answer:

True

Explanation:

There are thousands of phytochemicals, and research on specific ones is limited.

However, there is a strong correlation between foods rich in phytochemicals and disease risk. This suggests that taking phytochemical supplements can provide health benefits.

For example, scientists have found that increased consumption of fruits and vegetables reduces the risk of coronary heart disease, cancer, Type 2 diabetes, and neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

Which one of the following statements is FALSE? a In a neutralization reaction, an acid reacts with base to produce a salt and H

pishuonlain [190]

Answer: Option (c) is the correct answer.

Explanation:

HF is a weak acid and not a strong acid. This is because fluorine is a highly electronegative atom and when it combines with a hydrogen atom then it will attract the valence electron of hydrogen atom more towards itself.

As a result, it will not dissociates easily to give hydrogen ion. Hence, it acts as a weak acid.

A neutralization reaction is defined as a reaction in which an acid reacts with a base to give salt and water. For example, $HCl + NaOH \rightarrow NaCl + H_{2}O$

It is true that, spectator ions "appear in the total ionic equation for a reaction, but not in the net ionic equation".

Titration is defined as a process in which concentration of an unknown solution is determined using a solution of known concentration.

Thus, we can conclude that the statement HF, HCl, and HNO3 are all examples of strong acids, is false.
