I thought 1 of two reductions occurred SO₄^2- + 4H₂O + 8e- -> HS^- + 8OH^{+ and another one similar Or are you talking about the acid reaction, but even for that I only have 8 hydrogen ions and no hdrigen sulfate produced}

Ok so most of this topic is fairly ok to understand. But in making my notes I came across two conflicting sources surrounding point 6.1 (and thus 6.2 6.3 becasue they are closely related) Specifically relating to anaerobic bacteria and the chemical reactions that relate to corrosion at...

I have decided to use Fight Club as one of my related text for the area of study. Now while still trying to find out exactly how I am meant to make textual examples for journeys (segments or the entire journey) I am having some trouble with examples. I know this text is full of examples of...

Am I here? Isn't here just there without a 't'? Quanta - Quarks

Thanks heaps guys, you have been a great help. I can't believe I missed the F=ma one, so damn obvious... Thanks a bunch much appreciated.:wave:

I think our teacher isn't teaching us adequately, that or this is a bogus trial HSC because I can't answer this question about Escape Velocity. Describe the method Newton used that allowed him to show how the 'escape velocity' of earth could be calculated. (3mks, 9 lines) I wasn't sure but I...

For a band six response you would mention carbon compounds, they are relevant specifically to the combustion process which you are asked to outline. So yeah mention it. But don't forget you have to answer the question by comparing it with another alcohol.

Yeah it was thanks very much Zero. chousta, I guess it is saying explain how the observations made show that the plane is in an inertial frame of reference with the coin.

Fairly basic question I know but the experiment we did for this was a bit unorthodox and didn't explain it to me. So could someone help me out here. You are flying on aplane at a constant velocity and drop a coin out of it, describe the motion of the coin as you observe it from the plain...

Re: help with dot-point: • Process information to describe recent discoveries of elem I recently completed this pointmyself and was a bit shady on to what depth. But they method I used was I went to web elements and looked up ununium, it has a brief note on how they are made (like bombarded...

We only made it half way into point 4 so I can only hepl you a little. 1. Relativity was first postulated by Galileo, and was imbodied in Newtons First Law. As for inertial frames of reference, my understanding (we have the worst teacher so it could be wrong) is best explained by the following...

Thanks heaps man. I got as far as trying to use the formula that you end up with and reverse engineer the equation but I just couldn't see it. I looked at the question that we were asked in case I transcribed it wrong, but it turns out that they must have made an error. Because it says second...

Bump. Anyone have a clue as to how to do the first question using keplers laws

Ha ha, think again lassie. You're not the only person west of the mountains here. St. Stanislaus College.

The experiment made light travell perpendicular to, and against the aether. The idea being that if aether exists, being a medium of light, and it was moving, then it would make the light move too. almost like a leaf in a steam, if the stream is moving the leaf will move in the same direction as...

I have some formulas for series. Arithemtic Series: SUM OF TERM Sn=n/2(a+L) or Sn=n/2{2a+(n-1)d} General Term Tn= a+(n-1)d Geometric Series: General Term Tn=ar^n-1 These are incomplete there are more. I just don't know them as...

Yeah I understand all f what you said. I get that whole bit. I spose there are just two sides of the coin. Like everything in math, there are always little things that contradict. I also understand that there are more proofs that are far more elegant and shoot what I said down in flames...

Sorry but that is not really correct. The way I see it is that 1/3 =/= .33333333.... to start with. 1/3 is merely a representation of .33333... . A symbol in society may represent a company it doesn't mean that the symbol itself is that company. By the above logic that you have displayed coupled...

The issue with the pendulum experiment is that it is in the syllabus. This means that if you are trying to use this experiment for an open ended investigation as an assessment for the HSC then you cannot. This is because for an experiment to be considered you are not meant to know the outcome...

Thanks guys. It is so easy to see now. I must hav ehad amental blank or something and didn't think to make t the subject of the equation. Any ideas on the first question I am still stumped as a way to relate the inverse square rule to keplers second law. I'm sure that if I could do that I...
