10 CHEMISTRY OUTPUTS AND PROPERTIES, CaCO 3, colourless gas # #, white #,…

- - - - Magnesium Ribbon #
    - - Magnesium Oxide
    - - #Burns with DAZZLING WHITE LIGHT #
      - HEAT # TAKEN [endothermic]
  - - - Dil.Sulphuric Acid
        
        Zinc Granules
    - - Hydrogen
        
        Hydrogen is a combustible gas and burns with a popping sound.
      - Zinc Sulphate
    - - #displacement reaction # # # #
        
        zinc being more reactive than hydrogen displaces it from the acid and forms zinc sulphate and hydrogen gas.
  - - - Calcium Oxide
        
        Water
    - - Slaked lime [calcium hydroxide]
    - - hissing sound #
        
        Reaction of calcium oxide and water yields calcium hydroxide and energy. The reaction is exothermic in nature. That is why a hissing sound is produced due to the release of considerable amount of energy.
      - #exothermic
  - - - Lead Nitrate
    - - Lead Oxide
        
        [Nitrogen Dioxide]
        
        reddish-brown gas
        
        oxygen
        
        test increases flame
        
        yellow
    - - endothermic # #
        
        decomposition #
  - - - carbon electrodes
        
        water
        
        6V battery
        
        cathode
        
        anode
    - - hydrogen
        
        oxygen
        
        test increases flame
        
        test extinguishes flame with pop sound
    - - catalyst
        
        Dil.Sulphuric Acid
  - - - Silver Chloride
        
        sunlight #
    - - Silver
        
        Chlorine
        
        yellow
    - - photolytic decomposition
  - - - copper sulphate
        
        iron nail
        
        blue
    - - iron sulphate
        
        copper
        
        brown
        
        green
    - - When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore copper sulphate solution colour changes from blue to pale green
  - - - barium chloride
        
        sodium sulphate
    - - Barium Sulphate
        
        Sodium Chloride
    - - double displacement
  - - - Ferrous Sulphate Crytals #
