The Courses
1.Physics of Motion
2. More Chemical Reactions
3. Evolution
4.Waves
5. Biology of the Future
School Certificate Exams.
We have covered Motion, Distance, Displacement, Speed, Veliocity, Force Acceleration, Newtons laws
We are completing Chemistry. We have looked at Acid Base, Formulating Salts, Word Equations, Balancing Equations
And now we are working through Decomposition, and Combustion.
Decomposition focuses breaking appart and usually takes energy
Combustion focuses on bringing chemical together an usually emmits energy.
We have seen this decompostion reation
Acid + Carbonate -> Salt + Water + Carbondioxide
looking at this in longer form this is
H+Nonmental + MetalCarbonate -> metalNonmetal + water + Carbondioxide
Balance
HCl + CaCO3 -> CaCl2 +H20 +Co2
Another decomposition reaction will be demonstrated by heating Copper (valence +2) Carbonate (valence -2)

About Me
- drhill
- I come from a Science family: My father Geoffrey Hill was Australia's first computer programmer on CSIRAC the fourth computer in the world. He is credited with invention of Computer music and the development of “Interprogram” a language before Basic. My PhD is in Atomic and Molecular Physics. I have researched the activated oxygen layer above the ozone layer, and 'Assigned' the world's smallest molecule. At the University of Toronto I researched high power UV lasers. I have specialized in automation in fibre optics. This developed into research in Machine Intellect and Robots. I have enjoyed work as an Explainer with Questacon and my time as a part-time soldier. I currently teach High School Science at Epping Boys’ High.
