Copper Cycle Post Lab Problem 1. Use the following bolded terms to report the reaction type of the following balanced chemical equations: Redox—simple combination OR Redox—decomposition OR Redox—single displacement, OR Non-Redox—precipitation OR Non-Redox—neutralization Cu(s) + 4 HNO3(aq) → Cu(NO3)2(aq) + 2 NO2(g) + 2 H2O(l) Reaction Type: Redox—single displacement CuO(s) + H2SO4(aq) → CuSO4(aq) + H2O(l) Reaction Type: Non-Redox—neutralization CuSO4(aq) + Zn(s) → ZnSO4(aq) + Cu(s) Reaction Type: Redox—single displacement Zn(s) + 2 HCl(aq) → H2(g) + ZnCl2(aq) Reaction Type: Redox—single displacement

00:01 Hi, in this question we are given with four reactions and we are asked to give the correct type of reaction here.

00:06 In the first reaction, copper metal react with 4 hno3 to produce cono3 whole twice, that is copper nitrate, plus 2 no2 gas, plus 2 h2o liquid.

00:18 Here we can see that copper in the reactant side is present in zero oxidation state, whereas in product side it is present in plus 2 oxidation state.

00:27 And nitrogen in hno3 in reactant side is present in plus 5 oxidation state and in product side in no2 it is present in plus 4 oxidation state.

00:38 We can see copper is oxidized from 0 to plus 2 oxidation state whereas nitrogen is getting reduced from plus 5 to plus 4 oxidation state.

00:50 It means the given reaction is redox reaction and under the redox reaction it is single displacement reaction.

01:14 It means in single displacement reaction the one element that is copper is substituted for other element in a compound generating a new element.

01:29 Or compound as a product.

01:32 Here is the second reaction in which we have coo, that is copper oxide, which react with sulfuric acid that is h2so to produce copper sulfate and water.

01:45 We can see copper oxide is a base and sulfuric acid is an acid.

01:54 When base an acid reacts, there is formation of salt that is copper sulfate and water.

02:01 That is h2o.

02:03 In this reaction we can say that we are getting a neutralized product.

02:09 It means this reaction is a non -redox reaction under which it is neutralization reaction.

02:29 It is non -redox because copper in reactants side is present in plus 2 oxidation state.

02:36 In product also it is present in plus 2 oxidation state...
