Answer 2

1)The oxidizing agent is Li, and the reducing agent is S.

2) The oxidizing agent is Br2, and the reducing agent is Cs.

3)The oxidizing agent is N2, and the reducing agent is Mg

4)The oxidizing agent is O2, and the reducing agent is Fe.

5) The oxidizing agent is Cl2, and the reducing agent is NaBr.

6) The oxidizing agent is F2, and the reducing agent is Si.

7) The oxidizing agent is O2, and the reducing agent is Ca.

8)The oxidizing agent is HCl, and the reducing agent is Mg

9)The oxidizing agent is H2O, and the reducing agent is Na.

In the reaction 2Sr + O2 → 2SrO, Sr is oxidized (loses electrons) and O2 is reduced (gains electrons). The oxidizing agent is O2, and the reducing agent is Sr.

In the reaction 2Li + S → Li2S, S is oxidized and Li is reduced. The oxidizing agent is Li, and the reducing agent is S.

In the reaction 2Cs + Br2 → 2CsBr, Br2 is reduced and Cs is oxidized. The oxidizing agent is Br2, and the reducing agent is Cs.

In the reaction 3Mg + N2 → Mg3N2, N2 is reduced and Mg is oxidized. The oxidizing agent is N2, and the reducing agent is Mg.

In the reaction 4Fe + 3O2 → 2Fe2O3, Fe is oxidized and O2 is reduced. The oxidizing agent is O2, and the reducing agent is Fe.

In the reaction Cl2 + 2NaBr → 2NaCl + Br2, NaBr is oxidized and Cl2 is reduced. The oxidizing agent is Cl2, and the reducing agent is NaBr.

In the reaction Si + 2F2 → SiF4, Si is oxidized and F2 is reduced. The oxidizing agent is F2, and the reducing agent is Si.

In the reaction 2Ca + O2 → 2CaO, Ca is oxidized and O2 is reduced. The oxidizing agent is O2, and the reducing agent is Ca.

In the reaction Mg + 2HCl → MgCl2 + H2, Mg is oxidized and HCl is reduced. The oxidizing agent is HCl, and the reducing agent is Mg.

In the reaction 2Na + 2H2O → 2NaOH + H2, H2O is reduced and Na is oxidized. The oxidizing agent is H2O, and the reducing agent is Na.
