just anything on the standards potential page which we dont have to remember for the exam
use an equation to show the formation of a condensation polymer, im really stuck on this one :S
-exclusion of air
-removal of microorganisms
-use of high temperatures
- low temps
- drying
-chemical preservatives
-irradiation
and that question isnt in the syllabus?
when does storage and food manufacture take place?
polystyrene
properties- hard, transparen. polystyrene foam is light and a good thermal insulator
uses-food containers, packaging, apple trays, TV cabinets, CD and casette cases and plastic cups
use an equation to show a substitution reaction
-rise burette with small amount of the solution of known concentration and discard
-overfill burette with this known solution and run the excess out. Solution level should be on 0.
-use pipette to measure a given volume of the solution of unknown concentration into a flask and place it under the...
there are no futhur naturally occuring elements waiting to be discovered. Scientists are always trying to make new artificial elements which will be radioactive and remain in existance for a very short time, or may try and make artifical elements already invented by new means. So any of the...
answers i was reffering to were
-physical changes
-chemical reactions
-activity of enzymes
-attack by rodents or insects
-activity of microbes
hmm thats a hard one
-environmental issues (clean air and waters act)
-pricing issues, (trade practices act)
-labelling requirements and their...
assess hazards, identify CCPs, set standards for CCPs, monitor CCPs, lay down procedures for dealing with problems, keep accurate records of tests done at CCPs, verification
what are causes of spoilage?
-it is Aus's largest manufacturing sector
-contributes 25% of all exports
-exports a large quantity of raw materials and processed foods
-employes 8-9% of all working people
-largest employer in Aus
-food service and catering has expanded as a result of Aus's booming tourism industry
not quite...
i know this sounds horrible but thats good to hear, cause i see you do cosmology and did accelerated maths and all the really like super smart people on here seem to have endless textbooks and go to tutors and lectures and i was always under the impression the kids with all the resources are the...
oxidation states give an indication of electron transfer in redox reactions with oxidation being an increase in oxidation state and reduction a decrease in oxidation state. my question is above
biopol, it is produced industrially by bacteria growing in tanks with a carbon-based food source. The polymer is then isolated and purified. Recently attempts to produce the polymer have used genetic engineering. Advantages of this are faster growth, better yields, easier recovery and production...
