riadik2000 [5.3K]

Answer:

HCl

Explanation:

Some easy ways to identify if a compound is an acid is to locate an H+ proton, while basic compounds will have an OH- ion.

Examine all the choices:

A) NaOH

Already, we see that OH is here, so it's a base, not an acid. Eliminate.

B) NaCl

This doesn't have an H+ or an OH-, so it's not an acid. It's actually a salt. Eliminate.

C) HCl

This does have an H+, so it's an acid.

D) CH_4

Although this does have an H, it's a hydrocarbon - an organic compound. So, it's not an acid.

The answer is thus C.
