Step-by-step explanation:

Vinegar is a dilute solution of acetic acid. It has a sour taste and turns blue litmus red.

1) NaOH and 3) lye are bases. They both have a slippery feel and turn red litmus blue.

2) Water is neutral. It is neither an acid nor a base.

4, 3, 1

Explanation:

Sb has four on the right, so it needs four on the left. It's all alone, so 4.

O2 comes in pairs, so you only need 3 of those to get six oxygens.

And 1 is the place holder for the right side since we got the left to match perfectly.
