Question

Classify each of the following chemical reaction (check all that apply) :

Answer 1

Answer:

(1 ) acid-base, double replacement

(2) double replacement

(3) combustion, combination

(4) double replacement, precipitation

Explanation:

(1)  Recognize this as  the reaction of the acid (HI) with the base (NaOH) to produce salt (NaCl) and water.

This reaction is also a double replacement since Na replaces H in HI,and H replaces Na in NaOH.

(2) Here we have a double replacement where Cu replaces Zn in ZnCrO4, and Zn replaces Cu in CuSO4

(3) Here we have the combustion of the organic compound  CH3CH2OH (ethanol) with oxygen to produce CO2 and water.

This reaction is also a combination reaction reaction of oxygen with  CH3CH2OH

(4) This reaction is also a double replacement where Ag replaces Na in NaCl and Na replaces Ag in AgNO3

The reaction is also a precipitation reaction where a precipitate AgCl is formed from the reaction of aqueous NaCl plus AgNO3  to produce solid AgCl and aqueous NaNO3.
