Question

read the next section of the openstax reading before answering the question on the right. hcl is called hydrochloric acid. what was added to give this molecule its appropriate name? hydro- was added to the beginning. the first term gained an -ic. the term ends in acid. the number of atoms is specified.

Explanation:

Binary acids (acids composed of two elements, one of which is hydrogen) are named using the prefix "hydro - " followed by the root of the non - hydrogen element and the suffix "-ic acid". For \(HCl\), the non - hydrogen element is chlorine. The root of chlorine is "chlor". So, "hydro - " is added at the beginning (to indicate the presence of hydrogen and that it is a binary acid), the root "chlor" is used, and the suffix "-ic acid" is added. The ending "acid" is part of the naming convention for acids. The first term (the non - hydrogen part) does not just gain an "-ic" in isolation (it is part of the full naming pattern for binary acids). Also, for binary acids like \(HCl\), the number of atoms is not specified in the name in the way described in the last option.

Answer:

"Hydro - " was added to the beginning, The term ends in acid.
