Question

Reactants are an acid and a base, which one describes this? 1. Acid base 2. Redox 3. Precipitation 4. Combustion

Answer 1

The answer is 1. acid-base

Step-by-step explanation:

This is pretty self-explanatory, when an acid and base react, it is called an acid-base reaction. Redox reactions are where two reactants exchange electrons, precipitation reaction is where a solid is formed, and combustion reaction is where a compound is reacted with oxygen so none of those can be the answer.
