Can anyone by any chance help me with this; Commercial 0.100M nitric acid is labelled as having a density of 1.005 g/mL. Take molar mass of nitric acid = 61 g/mol. The molality of the solution is: a) 0.102 m b) 0.101 m c) 0.100 m d) 0.0950 m e) 0.103 m :confused:

Oxidation occurs at the anode, reduction occurs at the cathode. In a galvanic cell the anode is the negative electrode, the cathode is the positive electrode. In an electrolyic cell the anode is the positive terminal, the cathode is the negative terminal. Hope that helps :)

QUOTE dikeymikey - "I'll miss chem heaps. I had the best teacher ever. Miss P you ROCK!!!!" I'll also miss chem heapsies, I kinda SUCKED at it, but I found it interesting and enjoyable (yea I'm weird lol) I also had the awesomest teacher - Ms P...where you from??

Could someone please explain the difference between a condensation and a dehydration reaction ... thanks..:)

I did environment, knew it from other subjects and can remember the definition really well :)

I did protection - just knew it better, but hate micro grrrr YAY no more micro :)

Hey, can anyone give me an eg/ of complete + incomplete combustion thankyou

Okiez, REALLY REALLY dumb issue, but it's just not working for me atm:rofl: . Could someone plz explain, using diagrams, the condensation polymerisation of cellulose. Thanking you in advance:) .

Does anyone have any, like ANY info on the combustion of petroleum? All i know is that it is the burning in air, and that's obvious. :burn:

Hey, would anyone happen to have a copy of the Kebachi case study??

Hey thanx for your help, that does make it clearer now - that it is renewable to a certain extent. I just found one of the sites I had looked at and it says; "natural rubber should be available indefinitely from renewable plant resources." So obviously I didn't read it correctly :(.

Hey, would any one happen to know if natural rubber is a non-renewable resource? I was under the impression that it was, as the main place that natural rubber is obtained from is some tree... therefore if there were no more trees, there would be no more rubber. However, a few sites seem to...

Does anyone have any idea what acetylene has to do with synthetic rubber? I think it's just used in the processes of making it.. but can't find info that's clear. Thanx :)

I have an assessment and what I have to do is.......................... " Discuss the issues associated with shrinking world resources with regard to a natural product that is not a fossil fuel." A few people have come up with things like dyes, diamonds etc/ But I wanted to do something a lil...

Okiez...seriously need help with this as it will be in a topic test..... Compare the stability of O gas to that of O3, and the relationship of that (stability) with their bonds. I have no idea :confused: all I know is O3 is more stable in water.....

12.Alternative chemicals introduced include chlorohydroflurocarbons and more recently hydroflurocarbons. a) outline a reason why these are considered more desirable than previously used CFCs. b) Unfortunately, most of the gases used to replace CFCs are a prob for a different reason. Identify...

okiez, I guess this may seem pretty simple, but just started on these thingo's and my teacher was away......and we got a sub not trained in chem :mad1: . 2. Haloalkanes have higher densities and higher melting and boiling points than their corresponding alkanes. Explain. I'm guessing that it...

okiez, not sure if this will help but it's worth a try I guess. On HSC online, http://hsc.csu.edu.au/ , it has it listed in chemistry - chemical monitoring and management - 5. monitoring and management in water, and it has these links that it says are useful...

thankyou so much :) . I was looking everywhere, I did look on wikipedia, but obviously not the right stuff.
