  1.  
    1. J  Sulphur (IV) Oxide 
    2. K  Nitrogen(II)Oxide 
  2. V    NH4NO3(s)→  N2O(g) + 2H2O(l)        
    VI  SO3(g) + H2SO4(l) →  H2S2O7(l) 
  3.  Vanadium (VI) Oxide
  4. 2SO2(g)+O2(g) → 2SO3(g)
    Forward reaction leads to reduction in volume, high pressure is required to reduce the volume
  5.  
    1. Manufacture of fertilizer, Dyes, drugs, paints 
    2.   As a fertilizer 
  6. Product  SO42−/NO3
    Chemical test; To each sample add barium Nitrate for SO42− a white preicpitate is formed for NO3,no white precipitate
  7. Blue crystals changes to white powder
    Conc H2SOdehydrates hydrated copper sulphate
