A candle flame produces easily seen specks of soot near the edges of the flame, especially when the candle is moved. A plece of glass held over a candle flame will become coated with soot, which is the result of the incomplete combustion of candle wax. Elemental
analysis of a compound extracted from a sample of this soot give these results: 7.74% and 92.26% C by mass. Calculate the
empirical formula of the compound.

6.4 cm (max) - 25 cm (min)

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
