I'll take a stab at it, (haven't done ship wrecks for a year so bear with me) Pretty sure you have to combine the 2 equations you mentioned above to get a more definitive answer, acid has the ability to accelerate the corrosion because of the H+ ions it gives out. If you look at the first...

The mass is generally just the water, some teachers would tell you it is the combined weight but most of the time you will find it just the water

What about d since ur diluting it, the ph should increase i believe, but can't tell without calculation

^ agree with someth1ng, but it wouldn't hurt to get a general graps of the other 3 unbolded

Ethanol prac is just i believe spirit boiling water to see the amount of energy it exerts and what not shouldn't be too much of a hassle if you know the formula Water test sounds like it'll be similar to the sulphate fertilizer prac if u've done it, just get the test method for cations and...

Worse comes to worse ask for the criteria and try to point out that u had what they were looking for in the answer XD

Guys just remember the marking is based on your teachers discretion, although there might be a marking criteria its really based on your teacher :)

Keep in mind cohort performance will also play a factor in what you get :)

And how do u think they get a clean copy LOL

Nope sodium is a highly reactive metal, it is not passivating, because when it oxidates the layer it forms allows it to continue to do so, whereas aluminium when it oxidates it creates an inert oxide layer that prevents furthur oxidation hope that helps :)

Refer to the solubility table in conquering chem and just follow the flow chart there

I'm suggesting that they should maybe not base their whole mediation on one exam.... Like it seems fair when they tell you that school marks are moderated to the HSC, but how fair is that when you could get the hardest marker in school and the mediation still doesn't represent what you should...

I might be seeing it from a fence sitter position, i believe that it is good and somewhat fair in a way because it gives the atar a fair meaning since that is meant to be the rank that all aus uni's are meant to use, so in some respect everyone is studying the same thing and is given a fair...

I agree with enoilgam, the ancient is a better scaling sub in general. Which makes me hesitant to recommend or even consider to drop it since ur doing well. The mark you get and what it's worth changes year to year. But it is generally accepted that ancient does quite well when it comes to scaling

i have yet to come across a meter that doesn't spit out paper time-stamped and price paid, although i may be wrong, but why would u dump $52 in a parking meter thats pretty extortion LOL, wouldn't u just go to a car park at that rate unless ur at the airport?

The idea is to get the money spent to where it's meant to go. I think it should be amended though, so that recipients are audited on their expenditure and those that are unable to provide a legit use of their funds put into the program, or those who are seen to abuse their funds. This way it is...

Doesn't ruse get their students to accelerate one sub in the previous year and get band 6 then they are able to skim down even further on another subject so they are only really doing 8 units? From an original 12 unit build. But back to topic. It's really up to you, if your really confident...

Ok i think the explanation is that when you put a metal into another metal solution like so that also begins to compete with the metal electrodes. In which case like someth1ng said is the sodium solution. Also note the question asks for positive and in this case it leaves silver and tin and...

How i would study, well i would just get some familiarity with elements their valence some general properties and some core concepts. The other details should be stuff you should work out in the exam. The quiz itself should provide you enough information to solve the question or at least remove...

Most private lists are generated from Maths and English rates. I think SMH's list is generated from Total Band 6's / Total attempts conducted by students at the school. But isn't it illegal now to produce rankings of schools now?
