6 0

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.

You see, during winter days, <span>the sun is further down in the sky, so the same circle of sunlight covers a wider area, so there is less light per plant. In this case, those plants that are pointing straight at the sun have higher chances of growing better. Hope this answers your question.</span>
