    1) Disinfectant Solution (Alcohol + Water)

    2) Ice

    3) Chloroform

    5) Neon used in colored lamps

    6) Silicon used in any electronic circuit

    7) Graphite (in pencils)

    8) Tungsten lamp (contains a wick of Tungsten metal W)

    9) Charcoal (Carbon)

    14) Silicates (used as additives to detergents)

    15) Acetone (used to remove nails paint)

    16) Table Salt (NaCl)

    17) Potassium Iodide used to dissolve solid Iodine

    18) Silicon dioxide (sand)

    19) Na2CO3.nH2O (used in baking powders)

    22) Water molecules & Alcohol molecules

    24) Titanium Dioxide (a white permanent pigment used in toothpaste, paints and plastics)

    26) Paraffin wax (A candle wax)

    27) 1 mole (1 mole of anything contains Avogadro's number of particles of that thing)
