Energy changes and bonding
Read our general notes on Risk Assessment
The study of energy changes makes it possible to test the ionic model. In other words, it is possible to use data to decide whether or not it is possible to explain the properties of a compound of a metal with a non-metal purely in terms of ionic bonding.

Recently Asked Questions
- i've been told that the molar bond enthalpy for F-F is 159 kJ and for O=0 is 498 kJ. The overall enthalpy change for the reaction of 2 moles of fluorine with 1 mole of oxygen is -44 kJ. So how do I go about finding the mean molar bond enthalpy of the O-F bonds in oxygen difluoride? 210208
- Why is enthalpy of hydration always exothermic?
- I would like to investigate the relationship between alcohol classification (primary, secondary or tertiary) and combustion - looking at the energy of combustion (used to raise the temp of a known mass of water) and the amount of alcohol reacted with the oxygen (difference in masses before and after). I was just wondering how to go about this and also if there was any research about this relationship because I haven't been able to find any. Thanks.
