Hydrochloric is
an acid
a base
a neutral

A. acid

Explanation:

If youve ever heard the term, hydrochlori acid, then you would know it is an acid. Since it has a ph level lower than 7 it is considered an acid, due to the fact that a base woul dbe higher than 7 and neutral would be 7. Hope this helps!

i'm pretty sure its b i might be wrong though!

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
