Step-by-step explanation:

These are some unaccounted mass that was involved.

According to the law of conservation "matter is neither created nor destroyed but can be combined with one another".

  • The rule applies to all substances with no exception
  • When burning a candle, a phase change process is going on.
  • Some candle part of the candle occur in molten form whereas the other part is a solid.
  • In this experiment, the molten wax was not taken into consideration.
  • This accounted for the mass deficit.
