b. What type of reactions are these called? 2. Which reaction number above involves only one reactant forming more than one product and what type of reaction is it classified as? 3. Which reaction numbers involve two reactants exchanging cation/anion pairings
Please answer all questions below. Show work please.
Copper cycle involves five reactions.In the first reaction, copper metal is oxidized by nitric acid to form copper (II) nitrate, Cu(NO3)2. It is then converted to copper (II) hydroxide, Cu(OH)2, by reaction with base.
When this compound is heated, it is transformed to copper (II) oxide, CuO. Copper (II) oxide is then reacted with acid to form copper (II) sulfate, CuSO4. Finally, the copper ions in the copper sulfate are reduced to copper metal by magnesium.
1. Which reaction numbers involve copper changing its charge (oxidation state) in going from reactant to
product?
