Do model A and model B seperately. For example, the equation for model A is (W+N)^4, where w is working at 0.8 and n is not working at 0.2 Similarly for model B is (W+N)^3, where w = 0.6 and n=0.4 And remember to times the A and B since it says AND. Hope that helps

make two equations for the car and train with time variable let car = 40 + 40t train = 30+50t Use pythagoras theorem: distance = sqrt(distance of car + distance of train) then differentiate with respect to time substituting t = 1 ( after 1 hour)

i dun see the point of spending an hour on news sites every day. I did economics and i just flipped through the papers mostly reading headlines news on recent economic issues. Flip through the business sections (some of ross gittins articles are good) and just cut out the articles i like and...

I talked about both coz the question just said macro. But made sure wrote that RBA not controlled by gov. Think you needed both coz fiscal mainly for unemployment and RBA is for inflation targetting. Yea, pretty good paper. Seriously thought they would have something weird this year.

The government can run budget surpluses to reduce a deficit on the current account. By increasing taxation more than spending, the government can then use this to fund and reduce the deficit acquired. Question: Explain how movements in Australia's Exchange rate affect the level of foreign...

as long as you said how each of those factors relate to its solvent.

nope. There was one about ethanol as a solvent compared to water. Also the making of polyethylene compared to the other polymers.

haha. you too lets own industrial :D

My understanding is that Catalytic cracking is used to break down long hydrocarbons into an alkane and an alkene. It can't break down a molecule completely to ethylene like steam cracking can. Thermal/Steam breaks the hydrocarbons into very small chains like ethylene.

I say one of those screwd up questions where they give you the three different places on the map and you gotta discuss which plant goes where. Advantages/disadvantages for each position and make a judgement on the best option :D

Yes. Imo you should include diagrams. Our teacher said to throw in relevant diagrams but don't go too much detail over it (Like don't label it and say when the curve moves from E1 to E2 etc). Just quick sketch with a ruler and use it to quickly explain.

Thats the sodium hydroxide yea? Yea 3 different processes. But atleast the overall equation is pretty much the same. You just needa change the half equations. I'm seriously hoping for solvay process. Easiest out of the three i reckon.

man we have to learn like 3 different processes. Which have like 7 equations each their environmental effects And about soap, anionic and cationic and non-inonic detergents. So freakn annoying. Sorry i just wanted to whinge :(

WTF? People are trying to MEMORISE ECO essays??

Wat textbook do you use? Jacaranda Chemistry has info on all of them including the areas you mentioned.
