Chem syllabus question (2 Viewers)

[lyounamu]

LOL at u studious ppl... i can't do anything LOL how do u guys get out of holiday mode?

I got out of my holiday mode basically as soon as I got into the third day of my holiday. For the first two days of my holiday, I played about 10 hours of game each day but I elegantly planned how I would spend my holiday, what I would do and how I would come to achieve those objectives. Not all of them worked, of course but... it's great that I sticked to my initial plan.

Now - I am playing game to celebrate.

ok...my class just finished module 3 but i finished module 4 so i don't have to do any chem work for a while
Should you be revising any of your modules? I just do exercisises and module review from the textbook.

Yeah, I need to do some mole questions but whenever I get frustrated over questions, I want to kill myself and start a chain reaction of constant ranting and regretting for undertaking Chemistry in the first place.

Do you actually remember the formulas for moles? Just asking because it's way way way easier if you understand the concept of it being a big number.

Yes, I did memorise it. But I sometimes do some really challenging questions and my head explodes out of that.

Ttong: join in! I have got more rooms for more people as well.

I want in. What's so hard about learning mole formulas?

learning mole formula is easy. My only problem is an occasional mis-interpretation of the question. But I am better now since I have practised it a bit.

Yeah, I think with all Physics and Chemistry, knowing the Maths and formulae is the easiest part. The difficult bit is interpreting the question.

The formulas make it seem so hard though. :mad1:

 

[Aerath]

What are the formulas for moles?
n = m/M?

 

[12o9]

What are the formulas for moles?
n = m/M?

n = V/Vm
n= cV

uh thats all i can think of =/.

 

[bored of sc]

number of moles of substance (e.g. element, compound) = (mass of substance)/(relative atomic mass of subtance)

· Choose resource and process information from secondary sources to construct and discuss the limitations of models of ionic lattices, covalent molecules and covalent and metallic lattices

I don't really get what it this is referring to.

If you know attach your note on this dot-point please.

We had to use play-dough and cocktail sticks to contruct each of the models of:
> a named ionic lattice (e.g. sodium chloride)
> a named covalent molecule (e.g. water)
> a named covalent (network) lattice (e.g. diamond)
> a named metal (e.g. iron)

So for the ionic lattice I used a ball and stick diagram to construct a unit cell of sodium chloride (see attachment).

For the covalent molecule I used a similiar digram but for water (again, see attachments).

For the covalent network lattice I used an allotrope of carbon: diamond (see attachments).

And for the metallic lattice I used iron to form a regular cubic arrangement of balls of play-dough stuck together (no diagram for this one).

More will be posted up later.

Assignment.

My assignment in regards to the dotpoint.

 

[lyounamu]

You guys are bloody awesome.

I don't remember doing anything on that by the way.

Neither. I had no idea about this.

And hi Thomas.

Thomas?

Yeah. The name in Aerath's assignment.
