2. Yep you're right it could just be heating 3. What would you say instead? 4. Esterification can be exothermic or endothermic, yet for the HSC you can say endothermic for the purpose that it increases the yield. See here: http://community.boredofstudies.org/showthread.php?t=30164

Thanks

Yes I know it was contrast. But the methods are the same. So you can't contrast unless someone can correct me?

Target your weaknesses - is it including a suitable amount of examples? Analysing their effect? Also always make sure you start with a statement about belonging generally in all your answers (unless it tells you otherwise) BEFORE you analyse. i.e Text A elicits the idea that belonging to place...

Dissolved oxygen (DO) is the amount of oxygen dissolved in a given sample of water. Biochemical oxygen demand (BOD) is the amount of oxygen required for anaerobic bacteria within a sample of water to decompose the organic matter present. BOD is dependent on measuring DO because it is a measure...

Refluxing involves boiling the alkanoic acid and alkanol and then condensing the gas produced. This allows esterification to be carried out at higher temperatures, which increases the rate of reaction and the yield as esterification is an endothermic reaction (heat is a reactant, hence applying...

In english?

Transuranic radioisotopes are artificial elements that have an atomic number greater than 92. Commercial radioisotopes are those that are used on a regular basis for a specific use. Both can be produced by neutron bombardment and the acceleration of small particles. 1. Neutron bombardment...

Buffers are weak acids and their conjugate bases and hence can counteract any changes in pH. One buffer that is involved in the blood is haemoglobin, which is amphiprotic. In this case, it acts as a weak base; let Hb = haemoglobin: Hb (aq) + H3O+ (aq) --> [reversible] HHb+ (aq) + H2O (l)...

Just keep on going! That's all you can do - only a week left and do as much as you can! Like my sister always says - think of this week as extra i.e in addition to the 3 weeks. Think about it - what could maximise your marks? Just keep going, have regular breaks, diversify your study because we...

Best way I find is to remember all key ideas so you can mould to any question - definitely works for me - also reduces stress because you know you'll virtually be able to answer any question

Worst: english, chem Best: bio, geography, maths

I've got 3 solid ones and a 4th that I just skim over. Have more than 2 because your texts may not be pertinent to the question. So make sure you have 3 that are different imo

Yes I hate english too. But there is no point complaining about it! At the end of the day you're still going to have to sit the two exams so deal with it! And then after that you can run free LOL

Omfg I'm ecstatic! TO EVERYONE WHO SAYS IT WILL BE AS WORK DEMANDING AT THE HSC: It's only if you make it that. My sister does medicine at UNSW and she's having the time of her life! She does work but not all the time - she just has to pass! I cannot wait to start my course at Macquarie (B laws...
