(vi) Zn + NaOH-Na ZnO2 + H2
(vii) Na S,O3 + 2 Na S,06 + Nal
(viii) C2H6 + 02 CO2 + H2O
(ix) Ca P2 + H2O -Ca(OH)2 + PH3​

Answer 1

Answer:

1.SO2 + 2H2S → 3S + 2H2O

2.Al4C3 + 12H2O → 4Al(OH)3 + 3CH4

3.2KMnO4 + 16HCl → 2KCl + 2MnCl2 + 8H2O + 5Cl2

4.4 KMnO4 + 4 KOH → 4 K2MnO4 + O2 + 2 H2O

5.4FeS2 + 11O2 → 2Fe2O3 + 8SO2

6.Zn + 2NaOH → Na2ZnO2 + H2

7.L2 + 2Na2S2O3 → 2NaL + Na2S4O6

8.2C2H6 + 7O2 → 4CO2 + 6H2O

9.5NaP → 5Na + P5
