  • Chemical Properties 11
    • Chen takes a glass jar, sticks a candle to the lid, and then seals the jar. The mass of the jar-candle system is 1.1kg. The candle is lit and the lid immediately closed. What will be the mass of the jar-candle system after the candle has burned?
      • Exactly 1.1kg, because atoms were rearranged but not produced or destroyed
      • Less than 1.1kg, because the flame absorbed all of the oxygen
      • More than 1.1kg, because the flame produced carbon dioxide, which has more mass than oxygen.
      • Less than 1.1kg, because the heat from the candle increased the boyancy of the air in the jar.
