Sorry mate only realised you responded to this .. most are pming me lol.. 3rd exp isthe cross one the efect of tep on reaction rate

chobalt chloride dissolved in water- given eqn.
when the soln becomes blue is the reaction finished explain

describe how they were treated before becoming feed stock
one prdt of process that caused pollution
most important use of main prdt
what makes it suitable?
or

can anyone send me HL examcraft physics please????? ASAP!!!
if you searched the thread a bit you have found several good posts on Physics EC. I did mine today, here anywaysSection A-answer 3
Q1-Momentum/Velocity Collision of two bodies(air track/ticker tape)
Q2-Glass Block Snells Law etc {graph}
Q3-Fundamental Frequency of string{graph}
Q4-Electrical Resistance{graph}
Section B-answer 5
Q5-short questions answer 8
Q6-Scalars/Vectors
Q7-Resonance and stuff on sound
Q8-Radioactive Decay (i haven't covered this yet)
Q9-Capacitance/Resistance
Q10-Particle Accelerator thing?
Q11-Heat/Temperature
Q12-Pressure+Total Internal Reflection+Photoelectric effect+Electromagnetic Induction (do 2)
Heres a tip.....if it says"draw a suitable graph" then that means something of the results given MUST be changed.
Hope this helps(of coarse it will) Just please say if so!
Any questions please just ask
