Consider the reaction below.
zn(s)+cu2+ (aq) —> zn2+ (aq) + cu(s)
which half reaction correctly describes the oxidation that is taking place?
zn(s) --> zn2+ (aq)+e-
zn(s)-> zn2+ (aq) + 2e-
cu2+ (aq) + 2e-- cu(s)
cu2+ (aq)+e-- cu(s)

the answer to your question is c.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
