mmhmm would it be appriopriate to say....
Cl- is the weak conjugate base of the strong acid HCl.
and NH4+ is strong conjugate acid of the weak base NH3
so NH4+ preferentially reacts with water. forming a hydronium ion ?
can you ever got a worse combination... then Couchman and Jone (from the freakn stone age) and "Maths in Focus" (a year 2 kid could do all the questions)
Thats the books we use for 2unit and 3unit.
Makes no difference wat kinda book you use in the end. if you understand concepts thats all...
I was just wondering... someone was telling me no-one has ever got 100% for chemistry? is this true? if no'1s got 100 does anyone know what the highest mark has been :S
1) solve the inequality
1/(|x-3|) > 1/2
the | is absolute value sign............... i know how to do it without the absolute value sign... but i keep getting it wrong with the absolute value sign..
2) given a^x = b^y = (ab)^z prove 1/x + 1/y = 1/z...
mmhmm .....
my chemistry class is so weird.... we come up with the most impractical solutions to the worlds problems.........
eg1) somebody reasoned that we should speed up global warming by placing heaters at the south pole
eg2) "Miss if Ozone is bad in the troposphere, why cant they...
ok, i know NH4Cl is an acidic salt becuase
NH4+ + H20 -> H30+ + NH3
production of H30+ means its acidic salt
but my question is...... in the reasoning..... would you say.... NH4+ is weak base forming strong conjugate acid.?
if this is the case.... isnt NH3 a base.?
mmhmmm i fink what they mean by that is.... the distance from t=3 to t=4
applications of calculaus is my fav topic. but ive never seen questions like that..(about distance at 4th second) .. i dont think we will ever get one in the HSC as if there is any discrepencies as to how a question may...
mmhmm i had this problem... but i fink i understand how they cancelled out...
you know the (n - k +1) ! i fink dey broke it up into (n -k)! x (n-k+1)
they then equated demoniators..... blah blah blah... and cancelled out..
im pretty sure.... thats what happened :)
What contaminants cant membrane filters filter out?
... membrane filters avoid the need to chemically treat water right.... so what could they possibly miss out? some bacteria?
Any help would be appreciated thanks
hii, neva did consider med until undergoing my engineering degree, was just wondering, i got a uai of 65 and when i complete my degree, how hard would it be for me to do postgrad med?
what are the requirements, goals i should be aiming for?
thanks
lol whenever im stressed from PHYSICS !! i just do chemistry and maths.... soothing... lol.......... and when i feel like writing some BS i do english :)
i cant believe how stupid english is............. even a teacher at my school is like "we spend 2 years of our lives trying to teach...
