An acid is one that releases a proton, by the Bronsted and Lowry definition. Thus it turns to its conjugate base. A base receives a proton from the acid and becomes its conjugate acid. That is a conjugate acid/base pair. Question Describe the difference between a complete and incomplete...

I'll try my best to help - Chemical properties that make ethanol a good solvent Ethanol = Ch3CH2OH or C2H5OH the OH (hydrogen bonding) is polar and thus dissolves polar substances the carbon chain is non-polar and thus dissolves non-polar substances. THus it is a good solvent - small...

No, it's not the same. It was due to a change in classification. Before - Hominid meant humans and their fossil ancestors then due to rise in technology they found humans are ALSO related to the great apes. So now Hominid means the great apes & humans & fossil ancestors while Hominin is...

Well, I'm not sure about Quantas (cause that's not my case study) but in Australia stakeholders generally there is more of a pluralist approach to conflict.

Human story! I like it! Only because we got to go to the zoo! But otherwise there is too many long name (>_<'")

I am doing Industrial, well I don't mind. Even though I heard Shipwreck is easier, I'm hopeless with redox so its cool!

Re: What are your marks and UAI aim? I want to do Pharmacy in Sydney Uni or Commerce/Science in UNSW So I'm aiming for ATAR/UAI of 97+ (>_<)

Ozone is O3 which in the troposhere is dangerous because it irritates eyes and respiratory systens, in this case it is a foe. But in the stratosphere where their is an abundance of harmful UV rays O3 splits into O free radical and O2 thus stopping these harmful UV rays from reaching the earth...

CFCs are dangerous because they release an chlorine free radical, which in the troposphere reacts with the ozone (that is toxic) and save lives. But due to their inert nature, they float in to the stratosphere, where the ozone is NOT harmful but helpful in blocking harmful UV rays reaching...

Reaction - Haber process Temperature must be monitored in the Haber process, because it is an exothermic reaction thus the lower the temperature, the higher the yield. BUT it would lower the rate of reaction, extending the time taken to produce the desirable amount of ammonia. Therefore the...
