Hsc chemistry production of materials

Describe how commercial radioisotopes are produced. As the fossil organic reserves dwindle, new sources of the organic chemicals presently used have to be found. They generate electricity through the oxidation and reduction reactions shown below.

Beta-decay if there is a surplus of neutrons turn neutron into proton and electron and release the electron Release of positions if there is a surplus of protons Alpha-decay for a surplus of mass release of two protons and two neutrons which is a helium nucleus Petrol of this form is currently sold in Australia.

Distinguish between stable and radioactive isotopes and describe the conditions under which a nucleus is unstable. Since the Hsc chemistry production of materials carbon has already been assigned as carbon 1, the methyl group is located on carbon 2.

Any ethanol that is produced would be oxidised to ethanoic acid. The ions are collected by an electrode and the resulting electrical current measured.

As the cultural development of humans continued, they looked for a greater variety of materials to cater for their needs. The enzymes used industrially are produced by yeast and are extremely sensitive to environmental conditions.

Brazil is less affected by current depleting sources than other countries. They can kill cancer cells but also normal cells within a certain vicinity and is therefore useful for cancer treatment. Yeast is then added and air is removed. Substituents are atoms or groups which replace the H atoms, e.

Oxidation-reduction reactions — also called redox or electron transfer reactions. Its complete combustion can be represented in the following equation: An oxidation-reduction reaction involves transfer of electrons and thus can be harnessed to produce electricity.

The atoms of the more active metal lose electrons oxidised and they become cations. The ions are collected by an electrode and the resulting electrical current measured.

Molar of heat combustion: This end of the molecule can form hydrogen bonds or dipole-dipole interactions with other polar molecules. Examples of its use as a solvent: Molybdenum is adsorbed onto alumina and packaged into small glass tubes for distribution to hospitals, where it continuously decays into technetiumm.

This would lead to more Australian jobs: Cobalt is used both industrially and in medicine.

Naming Straight Chain Alkanols Locate longest unbranched carbon chain The ending of the name is determined by the principle functional group Number the carbons in the longest chain so that the principle functional group -OH for alkanols gets the lowest number Name and number all other functional groups For multiples of the same functional group use prefixes like di- tri- tetra- etc.

It emits gamma radiation, which can be detected by a machine outside of the body decaying into technetium Cloud chamber — radiation passing through supersaturated vapour of water or alcohol ionises some of the air; the ions formed act as nuclei upon which droplets of liquid condense, making radiation visible.

To produce the enzymes which catalyse the reaction Low O2 concentration The reaction is anaerobic does not involve oxygen. Social health and environmental: The small pulse of electricity produced is amplified and counted by attached electronic circuits.

When an atom is reduced its oxidation state decreases gain of electrons. Ethanol is soluble in polar substances e. The twentieth century saw an explosion in both the use of traditional materials and in the research for development of a wider range of materials to satisfy technological developments.

Added to this was a reduction in availability of the traditional resources to supply the increasing world population.

PREFACE HSC CHEMISTRY SYLLABUS NOTES – ANDREW HARVEY v PPRREEFFAACCEE Preamble These syllabus notes were written to help students to understand and succeed in Chemistry at High.

HSC - Year 12 - Chemistry. Production of Materials Fossil fuels provide both energy and raw materials such as ethylene, for the production of other substances Some scientists research the extraction of materials from biomass to reduce our dependence on fossil fuels Other resources, such as ethanol, are readily available from renewable resources.
