Question

what is the difference between a neutralization reaction and a double - displacement reaction?
double - displacement reactions are always redox reactions.
double - displacement reactions always involve acids and bases.
neutralization reactions always produce water and a salt.
neutralization reactions are always combustion reactions.

Explanation:

A neutralization reaction is a specific type of double - displacement reaction where an acid and a base react to form water and a salt. Double - displacement reactions involve the exchange of ions between two compounds and not all are redox reactions, nor do they always involve acids and bases. Combustion reactions involve a substance reacting with oxygen to produce heat and light, and neutralization reactions are not combustion reactions.

Answer:

C. Neutralization reactions always produce water and a salt.
