What did people put for the frequency question did frequency increase > or < or was it to do with wavelength?


i put > because the lines were getting closer at a higher frequency

I put "Hess' law states that the enthalpy change of a particular reaction remains the same independent of the route taken, providing the initial and final points are the same"

My exact words (literally the only thing I remember fully)

I said that but also said" provided the conditions remain the same "
For the first calculation did you put 0.23?

what did you guys put for mass one?

For energy density was it something 36200

41 for the enthalpy reaction thing?
What did you put for the Zinc one about what type of pollutant it is?

what did you put for the thermal stability question with the table?
B A C E D?
I didn't know wave particle duality was on the spec?
I put sulfur is insouble

For the order one about history was it something like B CDAE or something

or BDCAE can't remember

Yes I put something along the lines of that and then just struck in that enthalpy triangle 1 = 1+2

Well I ****ed up most of the calc questions....:frown: what about the bond angle one? was it Sio4 or Sio3 i forgot and for the emission spectra I put:
- electrons drop to lower energy level
- emit light/photon in the red region of the visible spectrum
- lines get closer at higher freq e=hv
-Should have done the maths questions 1st :frown:

I put this too and route 1= route 2 as said use the cycle

The greater the change in mass the less themrally stable it is.

Bubble gas through lime water, cloudly solution will form.

Observation seen sooner with carbonates that are less thermally stable.

I didn't even understand the letter question to put the theories in order, I put something like BADCE not entirely sure though, the revision guides have nothing on about shrodinger
