Indicate the state of each element (solid, liquid, gas, oraqueous). If the equation is an ionic reaction, then, write the corresponding total (or gross) ionicequation and the net ionic equation. If the equation is a redox (oxidation-reduction) reaction,then, classify the reaction in detail (e.g. hydrogen displacement redox reaction), write the half-reactions, the oxidation numbers of the atoms, and then, indicate which species (or element) isthe oxidizing agent and which species (or element) is the reducing agent.a.(10 points) Na2S(aq) + ZnCl2(aq) →b.(15 points) Fe(s) + O2(g) →c.(15 points) KClO3(s) → KCl(s) + O2(g)d.(10 points) HClO4(aq) + Mg(OH)2(s) →
