For the following reaction, identify the element that was oxidized, the element that was reduced, and the oxidizing agent. Give an explanation for each answer.N2O2a.oxidizedb.reduced

Given this chemical reaction:Sn(s)  +  2 HCl(aq)  →  SnCl2(aq)  +  H2(g)identify which substance is oxidized and which is reduced.oxidized: reduced: What compound is the oxidizing agent?:

Identify the substances that are oxidised and the substances which are reduced in the following reactions.(i) 4Na(s) + O2(g) → 2Na2O(s)(ii) CuO (s) + H2(g) → Cu (s) + H2O(l)Answer:(i) Substances oxidised is Na as it gains oxygen and oxygen is reduced.(ii) Substances reduced is Cu as hydrogen is oxidised as it gains oxygen.

In the following chemical reaction, which substance is the oxidizing agent and which is the reducing agent?PbO(s)  +  C(s)  →  Pb(s)  +  CO(g)oxidizing agent: C CO Pb PbOreducing agent: C CO Pb PbO
