Noticed there wasn’t one set up
Questions I remember:
1. 2 Conditions during dynamic equilibrium?
2. Buffers question
3 time of flight mass spectrometer question: calculate time in seconds
4 reaction of Al2O3 with H2SO4
5 draw phosphoric acid (formed from P4O10 reaction with water)
6. Calculate frequency from plancks constant and delta E
7. Oxidising agent used in electrochemical cell
8. Overall equation occurring in the cell
9. EMF of the cell
10. Shape of [CuCl4]2-
11. Relative abundance Q
12. Why is yellow light absorbed
13. Reaction of CuCl4]2- with ammonia and water
14Identification of sodium halides , Group 7 , Chlorine reaction
Why can’t too much Cl2 be used?
15 Bonding - shapes + mp of sodium chloride , chlorine and HCL

Definitely missed out on many questions so please add

CuCl 4- reaction with water and ammonia. Colour for it.
Why yellow light is absorbed.
Relative abundance
Identification of sodium halides , Group 7 , Chlorine reaction

1) I put- the rate of the forwards and backwards reactions are equal and the rate of conc and products being formed= constant
cannot remember buffers or time of flight

For emf i'm sure I got 0.40 V
shape= tetra
abundance i got 180 something like 186 maybe i cant remember accurately
yellow light absorbed as its complementary colour of blue is absorbed and then yellow is reflected blah blah due to its energy gap and electrons being excited
too much cl2 is toxic
the bonding shape was 104.5 degrees

the bonding question was okay

for the aqueous ammonia i put- whatever it was+ 6nh3--> [smth (nh3)4(h2o)2]2+ +2oh- + 2h2o and deep blue for the colour

What was the abundance question? Was that the one with the relative atomic mass?
