Q: Complete the reactions and write in words.
a) 2Mg+02-
b) SO2+H2O--
c) CuSO4+Zn---
d) Fe+O2+H2O--
e) 2Cu+H2O+CO2+O2--
f) FeSO4+Cu--
g) CuSO4+Fe-
h) Znso4+ Fe-
a) 2Mg + O2 = 2MgO Magnesium metal + Oxygen = Magnesium oxide
b) SO2 + H2O = H2SO3 Sulphur dioxide + Water= Sulfurous Acid
c) CuSO4 + Zn = ZnSO4 + Cu Copper Sulphate + Zinc metal = Zinc sulphate + Copper
d) Fe+O2+H2O-- 4Fe + 3O2 + 6H2O → 2[Fe2O3.3H2O] Iron+Oxygen+water = Ferric oxide (Hydrated)
e) 2Cu+H2O+CO2+O2=Cu(OH)2+CuCO3 Copper+ Water+Carbon dioxide + Oxygen = Copper hydroxide + copper carbonate
f) FeSO4+Cu = No reaction
g) CuSO4+Fe = FeSO4+Cu = Copper sulphate + iron = Ferrous sulphate Copper
h) Zn + FeSO4 ------> ZnSO4+ Fe = Ferrous sulphate + Zinc = Zinc sulphate + Iron
