Should Australia reduce its use of coal and build its own nuclear reactor for generating energy?
... the production of nuclear weapons. Many people believe that these risks are small and can be reduced by the technology in the new reactors. They insist that the safety record is already good when compared to other fossil-fuel plants that it produces much less radioactive waste than coal power ...
Investigating Some Factors Which Affect the Rate of Reaction.
... the Rate of Reaction Between Hydrochloric Acid and Sodium Thiosulphate Background Information Reactions can be completed at different rates. The rate of reaction is measured by observing how quickly reactants are used up or how quickly products are forming. This can be calculated in ...
Year 12 Chemistry Preliminary Assessment Task 2: The Chemical Earth And Metals
... the first metal to be used by humans. The period in which copper was readily used was regarded as the transition from the Stone Age into the copper age. This was a very important time in our history. In the early years, copper was used to make tools, weapons and cooking equipment. The Egyptians ...
An Investigation Into The Volume Of Gas Produced When You React Hydrochloric Acid And Marble Chips - Plan, Evaluation And Analysis
... carbonate. However to maximize gas production we used an excess of marble chips. So the weight of chips weused for both my preliminary work and my real experiment was 5.5g抯. So I used 50ml of 2 molar/dm� hydrochloric acid and 5.5g抯 of marble chips in ...
Title: Conservation of Energy Lab Purpose: To verify that the total energy of an object doesn't change if the object hasn't done work.
... in energy can be accounted for by friction between the small piece of PVC pipe and the inner wall of the large pipe, as well as the impact of air molecules on the small piece of PVC pipe . Sources of error for this experiment mostly come in the ...
Nuclear Power: Pros and Cons
... power plant can blow up like a nuclear weapon. 11. Some nuclear waste products must be stored for centuries so radioactivity cannot escape. 12. New dangerous elements are being invented every day. 13. Nuclear power plants produce material that can be converted into nuclear weapons. 14. All nuclear ...
The History of the Periodic Table
... In the early eighteen hundred's, Dobereiner discovered that elements that are similar in appearance and behavior also have similar atomic masses. At the same time, Dechancourtois made a cylindrical table of elements to show the reoccurrence of properties. In the ...
How paintballs are made
... the gel is transferred from the mixer into a heated vat called the "gel tote". Once the filtered gel is securely in the tote it is lowered into a giant blender where food dye is added and blended for about 20 minutes. Elsewhere in the factory, the same method is used ...
Chromatogrophy
... using the Carotenoids mixture from part one. Repeatedly apply annatto extract to this same spot multiple 5-10 times. Multiple spotting allows the detection of Carotenoids that are only present in minor amounts. Allow the spot to dry for 2 minutes. Run each TLC plate in the ...
Dihydrogen momoxide
