    sucrose, C12H22O11
    ethyl alcohol, C2H2OH
    glycerol, C3H5(OH)3

    glycerol, C3H5(OH)3
    potassium iodide, KI
    sucrose, C12H22O11

  • Part 8: In order for a substance to conduct electricity... (which is not true?)
    it will have to be an ionic substance
    It will have to be in solid form
    it will have to be dissolved in water
  • Part 9: 30 g of K2CrO7 dissolved in 100g of water at 50 C would be considered____________
