Should Australia reduce its use of coal and build its own nuclear reactor for generating energy?
... of 50 million tonnes of carbon dioxide per year. Every 22 tonnes of uranium used saves the emission of one million tonnes of carbon dioxide relative to coal. Although nuclear power plants give out less carbon dioxide, it produces other pollution such as radiation and radioactive ...
Investigating Some Factors Which Affect the Rate of Reaction.
... collisions can take place. In the following experiment, the effect of concentration on the rate of reaction between hydrochloric acid and sodium thiosulphate will be investigated. Concentration is easy to measure and the rate of reaction ...
An Investigation Into The Volume Of Gas Produced When You React Hydrochloric Acid And Marble Chips - Plan, Evaluation And Analysis
... effect the rate of reaction with marble chips. I will measure the rate of reaction by measuring the gas produced when the reaction occurs. My variable will be acid concentration , and I will keep every other aspect of my experiment the same. (Volume of acid, conical flask used, volume of water ...
Year 12 Chemistry Preliminary Assessment Task 2: The Chemical Earth And Metals
... of electrons and filled electron shells increases, but the number of valence electrons remains the same. The outermost electrons in a group are exposed to the same effective nuclear charge, but electrons are found further from the nucleus as the number of filled energy ...
Chromatogrophy
... used adsorbents. The Adsorption strength of the stationary phase is determined not only by the chemical nature of the adsorbent, but also by its particle size and the amount of water it contains. However, the polarity of the solvent should be comparable to the polarity of ...
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 ...
How paintballs are made
... of non-toxic, food grade ingredients. To make the hallow shell; water is poured into a giant, heated mixing bowl. A sweetener, a preservative and a secret combination of ...
The History of the Periodic Table
... physical properties of missing elements based on the trends of the periodic table. He began by writing fact about each element on paper cards. On those cards, he wrote information such as melting points, densities, colors, atomic masses, and bonding powers. Afterwards, he ...
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.
... .0115s 2.0116s 3.0118s Calculations: TE = Total Energy PE = Potential Energy KE = Kinetic Energy m = mass g = gravity = 9.81N/kg h = height Calculating the TE of the small piece of PVC pipe at the top of the tube before we dropped it. PE=mgh ...
