Uh, should I be worried? We started monitoring today. Week 5. Term 2. Fuck.

I think karam means like the standards packages and that..

How many moles of H+ in 25.0mL of 0.1M HCl? The book is saying n=2.5x103 moles of HCl and also of H+ But I keep getting n=2.5x10-3 My working: C=0.1 V=0.025 n=CV n=0.1*0.025=2.5x10-3

Yeah. Well it is close enough, the answer is 6.12L so it is just dependant on your accuracy. Thanks

Can someone please do this question, with working. I keep getting the wrong answer.. Thanks :) The burning of sulfur can be described by the following equation: S(s) + O2 (g) --> SO2 (g) What volume of sulfur dioxide will be released at 25oC and 101.3 kPa when 8.00 g of sulfur is burnt?

Aww, thanks for that. :) Chem is on Monday 15th, and Physics on Wednesday 17th... Whenever your free, if its possible before the weekend would be excellent :)

Does anyone have any half-yearly exams from there schools on chemistry (or physics) that you could possibly scan for me and email them to draped.and.displayed@gmail.com. Thanks And yes, I have gotten the ones of the resources.

Draw a sketch graph for the function showings its important features. y= (x+3)/(x+1) Thanks.

Which is better at avoiding data collision, CSMA/CD or Token Ring. Explain why.

Eeek. I meant in terms of x not t sorry.

Can someone help please :) A particle is moving in SHM with displacement, in metres, over time t seconds, given by x = 2 sin 6 t. Find the equation of the velocity of the paticle in terms of t. ........... x= 2sin6t x'=12cos6t x"=-72sin6t=-36x ...........

True, posted incorrectly. Should be +9

Oh my god. lol so much fighting! I worked it out to be f"(x) = 12x - 18 f'(x)= 6x^2 - 18x + C when f'(x) = 0, x=2 0=6(4)+18(2)+C C=-60 therefore f'(x)=6x^2 - 18x - 60 f(x) = 2x^3 - 9x^2 - 60x + C (2,-8) -8=2(2)^3 - 9(2)^2 - 60(2) + C C=60 f(x) = 2x^3 - 9x^2 - 60x + 60

Q1 curve y=x^3 -2x^2 -4x +8 find the points where the curve meets the x-axis Q2 gradient fucntion of the curve is given by 4x^3 -2x +3. the curve passes through (-1,2) where does the curve cut the y-axis Q3 the point (2,-8) is a turning point of the curve y=f(x) f"(x) =12x +18 a) find...

∫13 to 9 dx/(x-7) How do I intergrate that?

A long jumper left the ground at an angle of 15degrees and jumped a distance of 7.0m. Considering this result, caluculate the velocity of long jumper when leaving the ground. How would I go about answering that?

HSC - 2006 Internet, broadband. More than 20 hours.. 90% educational Uai of 93.. hopefully

At the start of Yr 11 last year we had a girl who was 26, had 3 kids and divorced at our school. Teacher's thought it was funny though when she was not only older than them, but had phone call's from her children's school. lol. She dropped out near the end of year 11 though.

2 Information Processes and Technology 77/100 77/100 77 4 Better than I expected. Lol. Reapeating for 06 tho.

Well... You have a fairly bias view on it. I love maths, and think that should be complusory - but you mighten because you don't enjoy it. I don't mind English, however I don't think that it should be complusory - how will it help me in University studying Science or Maths... or really anything...
