base Give OH ions and acid gives H ions
Acid
Butane is neither an acid, a base, nor a salt. It is a neutral molecular compound.
If you meant HCl, Hydrochloric Acid, it is a strong acid and not a base. A way to tell if it is an acid is that it has an H+ in the chemical formula. Most of the time, if it is a base it has an OH- attached to the chemical formula, but this is not necessarily true for all bases.
No. Li2CO3 is a compound but it is ionic, not molecular.
HCl is hydrochloric acid and NaOH is sodium hydroxide a base.
An acid will dissolve something faster.

Ammonia is a base with the chemical formula NH3.
The amount of base depends on the chemical formula of the acid.
An acid tastes sour, and a base is bitter
It is a strong acid. Hint: if the formula begins with H it is usually an acid.
'HC2H3O2' is a rather poor way of writing the formula for ethanoic(acetic) acid. It is usually written as 'CH3COOH'.
