. Which statement accurately explains the reaction below?Fe2+(aq) + MnO4-(aq) → Fe3+(aq) + Mn2+(aq)Manganese is oxidized from a +7 oxidation state to a +2 oxidation state.Manganese is reduced from a +7 oxidation state to a +2 oxidation state.Manganese is oxidized from a +4 oxidation state to a +2 oxidation state.Manganese is reduced from a +4 oxidation state to a +2 oxidation state.

What is reduced in the reaction below?2H2 + O2 2H2OA.Reduction does not occur.B.O2C.H2D.H2O

Find out the process of oxidation, reduction oxidizing agent, reducing agent from thefollowing: -(a) MnO2 + 4HCl MnCl2 + 2H2O + Cl2(b) H2S + SO2  S + H2O(c) CuO + C  Cu + CO

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.

Which statement correctly describes what is happening in the reaction shown below?2Mg(s) + S2(g) → MgS(s)MgS is the reducing agent.Mg is oxidized.S2 loses electrons.MgS gains electrons.Mg is the oxidizing agent.
