Organic chemicals would be Ethanol and other Carbon based chemical products. Biopolymer you should look at Biopol or PLA (poly lactic acid)

Not necessarily. Look at your writing skills. No offence but you have made a lot of grammar and spelling mistakes in three or four sentences... Can I ask you what you got for your UAI? If you got anything over 99.55 it would've got you into any of your desired courses (Maybe not into Medicine)...

Nickthebiscuit is correct. The answer to this question is 5.92 x 10^-5 N

Finding new materials are great for subjects like Geography and English but I wouldn't advice using new materials in Chemistry, why not just use Biopolymers like Biopol or PLA. There has been change in naming hydrocarbons, but NSW Board of Studies has marked down people answering it new ways, so...

Well answered XIAO but extensive information can be found in your textbook in the option topic shipwrecks, corrosion and conservation

Zingerburger's response to the impact of transformers on the society does not have sufficient information to receive a full mark. First he has covered the part the transformers play in the transmission of electricity, however he has not included the role the step up and step down...

The process of esterification requires very precise and pedantic measurements, what this requires is the minimal deficiencies in your result, just taking the lowest value of the three results would not be recommended, I doubt that any chemistry teacher would have said something like that. If you...

Methyl Pentanoate Esters from alkanols and alkanoic acid are named as alkyl alkanoates: the alkyl part of the name comes from the alcohol from which the ester was formed, and the alkanoate from the alkanoic acid. In your case: Methyl Pentanoate -> Methanol + Pentanoic Acid Hope you...

Quanta to Quarks is mine. It naturally flows on from the core modules.

Question: How do scientists check if the reaction is at an equilibrium.

I got 98% for Chemistry theory test and 100% for practical, quite proud. Average for theory was 54% Practical was 65% (Titration and indicators) Therfore my aggregate mark for Chemstry so far is around 97%

1. Identify the ions present in an aqueous LiOH solution. Li+ and OH- 2. How many moles of oxygen are there in 10.46g SO2 ? S=32.07 and O=32 add up to total 64.07 there is 5.22g of O2 Therefore (5.22/32)= 0.16 moles of Oxygen Gas Therefore 0.16 x 2 = 0.32 moles of oxygen atom (The...

Industrial Chemistry is mine!!!

what is your prescribed text? If it is 'On Giant's Shoulders' E-mail me to (Alfred_rulz@hotmail.com) I have already written a complete essay on it.

Michael Leunig's Cartoons are very Good for imaginative journeys especially the 'Cradle to Grave', song "Imagine' by John Lennon is an excellent related text depicting speculation and invention. If you want the song and cartoon file, send me an email to (Alfred_rulz@hotmail.com), you should be...

I'm happy with all my subjects... Maths Ext2, Maths Ext1, Chemistry, Physics, Geography and Advanced English. All together 12 Units. SOOOOOOOO Lucky I dropped BIOLOGY ^.^

AMPHOTERIC - Amphoteric substances are those which reacts with acids and can also react with bases. P2O5(s) + 3H2O(l) → 2H3PO4(aq) (phosphoric acid) or P2O5(s) + 6NaOH(aq) → 3H2O(l ) + 6Na+(aq) + 2PO43–(aq) HSC Questions will often ask to provide an equation with states of matter as well

Acids are commonly used as food additives. What really is important is that Acids can be added to foods as nutrient booster, flavouring, and preservatives 1. Citric Acid is added to certain foods as flavouring. It gives a tart taste. 2. Ascorbic Acid is added as a preservative 3. Acetic...
