measuring bond enthalpy

• specific heat capacity equation


  q = mc∆t
• specific heat capacity of water, c

  4.18
• specific heat capacity equation units, q = mc∆t

  q = heat (J)

  m = mass (g)

  c = specific heat capacity

  ∆t = change in temp. (°C)
• Possible reasons for a lower experimental value of enthalpy change of combustion:

  • heat loss to the surroundings
  • incomplete combustion
  • evaporation
  • non-standard conditions
