help; i really need a tutor

when the metal carbonate react with HCl



i.e. one mole of carbonate reacts with 2 moles of HCl.

20mL of 0.1M of HCl reacted,

which means that

we know that , transposing gives

now you can match up the correct option by finding the Mr of each.

oh yerrrrrr ...thanks mate

Phosphorous is present in many fertilisers
Phosphorus can be determined gravimetrically by carrying out a numbe of steps, eventually leading to its precipitation as insoluable Mg(2)P(2)0(7). In one such analysis, a 14.298g sample of fertiliser yielded 4.107g of Mg(2)P(2)O(7) precipitate.
(a) Calculate the mass of phosphorous in the precipitate.

I got 1.14g, but the book says 0.8967g.........What the?

Yeah I got the same as you - maybe you copied down the question wrong, or (more likely) the book could be wrong?

yer maybe the book is wrong...if the book is continuously wrong then what can i rely on?

I did tell you textbook questions are dodgy

lol....yer and u said the TSFX ntoes were dodgy....the only thing left to do is checkpoints and theres not many questions there

i must agree with the tsfx notes being dodgy. There's no doubting that. 135 for summer school methods and all you pay for is a book of repeated notes that you already have in your text book plus 6 hour lecture to which 90% of it you wouldn't have a clue what's going on as this is all extraterrestrial mumbo jumbo so far. i suggest Access Education. They give you some helpful pointers.

Agreed. TSFX teaches a lot of crap that aren't really on the course.

Access Education, on the other hand, teach you what is actually important. My experiences with them have all been excellent, especially chemistry. One of their chem lecturer, Chris Dwyer, is very awesome, ed_saifa can possibly tell you more =]

oh yerrrrrr ...thanks mate

khalil you only doing 5 subjects all up for vce ??

I wished i stayed at home and prepared for yr 12, make a mistake going on a holiday this yr.
Ow well, im not worried about me falling behind. I cant catch up and im pretty good in chemistry.

[AQ]

I dont know where it is just me or some of my holiday hw is really hard.....please help me out

Te is heavier than I, yet it is placed before I in the periodic table. Why?
115L of gas at 455mmHg is heated from 22 degrees to 350K. what is the new pressure?
A car burns 45L of fuel (75% octane and 25% nonane) in a week. What volume of CO(2) does this result in, at SLC.

there is more to come....if u can answer these u are a genius and should become my tutor

khalil dont worry..
I think theres nothing to worry about, you may feel like its hard becuase you havnt learnt it over school or you teacher may have just given it for you to attemp.
If you can't answer a question, best thing to do is leave it aside and move on. Don't ever worry about the question. you can ask your friends over VN (which they are very helpful) or you can ask your teacher.
btw, what school do you go to?

Yea thanks for the advice, although its not as easy as it seems. If i dont know a question(which happens a lot)....i relli cant be bothered typing up soo much for a simple question to be answered! and sometimes i haev to wait max 2 days. i noe it doesnt seem much but i tend to forget the question i asked to answer! plus my teacher is just as worse as me!
i go to Lyndale SC which is in dandy north (SE region)
im guessing ur turkish?
