Electrostatic forces of attraction between molecules…..electric feel(ds)

It was a complete coincidence that Sandy had the sniffer dog check out the lab before our lesson on functional group chemistry yesterday.

Test your skill at naming simple organic molecules as you relax to the sounds of classical and celtic music

Your mission……to produce a short video clip that demonstrated the electrical properties of ionic compounds. Here are the results.

Sarah and Josie have managed to break lots of covalent and ionic bonds to allow lead oxide, zinc oxide and boric acid melt and form a glass.

Remember art is just chemistry that looks good

First we take the clay and get creative.

All art is chemistry that looks good

What are silicate minerals and which ones are useful in pottery?

Bonding describes the forces that hold atoms to other atoms in elements or molecules. Bonding also describes the forces that attract molecules to other molecules in molecular compounds or ions to each other in ionic compounds.

Where do forces originate anyway. Let Brian Cox explain.

Physicist Brian Cox has two jobs: working with the Large Hadron Collider at CERN, and explaining big science to the general public.

Now read pagers 79-82 in the Wignall and Wales text book. Try exercise 9A then 9B

Quickfit apparatus has ground glass joints to prevent leakage of flammable vapours. Ben demonstrates how this equipment can be used to carry out a simple distillation……..eventually

You are not just chemistry students. You are actually training to become an architect or designer…………..at the molecular level. You are allowed to feel superior in most respects to unfortunates who have made poor course choices. Now do the tutorial.
