If a lab group were using hydrochloric acid to perform a substitution reaction, which precaution would not be a concern?

A Flammability

Explanation:

A Flammability

B Health

C Reactivity

D Contact

Hydrochloric acid will not burn under normal fire conditions.

A substitution reaction is one in which an element or atom in a compound is displaced or substituted by another atom in the course of the reaction.

Hydrochloric acid is a strong and highly reactive acid that has the ability to burn solid substances that come in contact with it. Hence, it posses a health risk when the fumes are inhaled or when it gets in contact with the skin.

Hydrochloric acid is highly reactive and considered as a strong oxidizing agent. It has the capacity to react with several metals to liberate hydrogen gas, reacts with carbonate compounds to liberate carbon dioxide gas, etc.

However, hydrochloric acid is not flammable and therefore, will not burn under normal fire conditions.

The correct option is A.

the answer to your question is c

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
