You would rank first for sure then.. :D
I checked her profile and it said that she is going to James Ruse.
Anyway, my school only has 5 guys in Ext. 2 class, and we have classes outside timetable on Wednesday after school and Friday before school + some random lunch time or recess.:D
My MX2 half-yearly will include curve sketching, complex numbers, conics, polynomials and probably some integration if we get up to that as my teacher said the integration would be where the easy marks come from.
Yes, that's what I and my teacher think, but that other teacher (we have 3 business classes) who marks my test thinks otherwise and now I know that mine was correct. I don't care if I can't get the marks, now I know what is correct for HSC. Thanks.:)
The ions that do not change before and after the reaction.
In your example, the ionic equation is:
SrCO3(s) + 2H+(aq) + 2Cl-(aq) → Sr2+(aq) + 2Cl-(aq) + H2O(l) + CO2(g)
You see that 2Cl- is the same on the left (reactant side) and right (product side) which means Cl- does not participate in...
Can you prove that one plus one is two? I heard someone has proved it with complex proof, dunno where to find it though. If one plus one is not two, everything else will fail.
Practical: use pH meter or indicators.
Theory: like Riviet said (Riviet forgot the minus sign in front of the log), but you can also change [H3O+] with [H+] as they both are practically the same thing. The difference is that [H3O+] is a [H+] that dissolves in water.
So, pH = -log10[H+]...
1. When you write ratio, like liquidity ratio, do you write it something is to one or one is to something? eg.
CA : CL
10000 : 15000
1 : 1.5 OR 0.66 : 1
2. When you calculate return on owner's equity, do you include retained profit (net profit) in your owner's equity or not? eg.

OK, I mean 6 sides essay for English, but that's just normal school works, not an assessment as my teacher want us to practice write fast about area of study or text on society... something like that... still I just write some smart BS most of the time.:p
My Physics teacher is so lame, he...
We usually have to write 6 sides in 30 minutes, and I'm only doing ESL...
I don't know. I thought it is the same for every other school.
Lunch is last for 29 minutes, from 11:58 am to 12:27 pm.
On Wednesday, we start school at 9:22 am.
Maybe that's why most students from my school got band 6...
