so far, only 3 marks lost on not multiplying by two in the molar heat of combustion, question 15 in multiple choice (put B, random guess) and not putting the metal name for the anode and cathode, only identified anode and cathode LOL. so yeh.. in the 90's hopefully.

it is A, because it has iodine, sure it could be B, except it said "UNAMBIGUOUSLY identify" and carbonate ions also precipitates with calcium (i.e limestone) and sodium (i.e sodium carbonate as seen in the solvay process). in relation to the pH question, by added lime to the water, this...

it means union, ie. together.

I go to terry's class, no cd's given out.

hey, no CO2 is a greenhouse friendly gas.

ur right, but the y value is irrelevant.

Hey, the reason for ma = mg -mkv, since every resisted near the earth, that is; where mg is applied, then m times R (R= resisted force), is required as all resisted motions near the earth is affected by mass. that is the reason for using mkv

easy question.... mass= 0.0889g of copper carbonate..
