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)
Write up the following Prac.

12 May Lesson
New learning Points
Indicators : Show pH, Universal, and Tumeric (record what they do)
Combustion is an type of Oxidation reaction. This is where a chemical gains O atoms. Corrosion is slow addition of O with water. Combustion needs heat to start, then the heat keeps is going. Detonation need sound and vibration to start and the sound and vibration generated keeps it going.
C + O2 -> CO2
Quick Revision
Motion Convert 1ms-1 to kmph
How fast is 72 kmph in ms-1?
What is the difference between Gravity and Force?
Learn Newtons three laws
N1 = with out force motion goes on
N2 = with net force a body will accelerate in the direction of the force
N3 = two bodies apply equal and opposite forces to each other
Apply N1,N2,N3 to various situations.
Chemistry
What is the Symbol for: 1) oxygen 2) neon 3) calcium
What is the name of these symbols: 1) Ba 2) Fe 3)Mg
Write the chemical formulae for 1) hydrochloric acid 2) sulphuric acid 3) nitric acid
Write the name and type of chemical for Ca(OH)2
Write the pH for 1)Lemon Juice 2) Water 3) laundry soap
Write the word equation for the addition of 1) and 2) of the last question
What is the formulae for
1) aluminum (+3) oxide (-2)
2) potassium (+1) nitrate (-1, NO3)
3) magnesium (+2) oxide (-2)
What happens when you add
1) metal + acid
2) metal + carbonate
3) acid + base
Name two indicators and how they work.

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.
