what did people get for the calculations?? I defo messed them all up 😑
I can't remember all of mine lol... I got +41 for Hess' law. -30,000andsomething for the energy density (which I think may be wrong), 33.something % for the HNO3 by moles.
These were my calculation answers, in order of how they appeared in the q paper Mass of air: 834.7 Mass of air for 1g of C4H10O: 11.28 Energy Density: 36200 Hess' Law: +41 KNOW: 34.15%
Not sure if theyre right but lemme know if you got the same/different
Got the same as you apart from the last one. The mass of air need question stumped me for a while lol 😂😂

I got the same for Hess' law and energy density, but that's it 😂 ffs
I can't remeber any of mine what did everyone put for the emission spectra one ?
I put, the electrons get promoted and then fall to a lower energy level. As they fall they emit a photon. E=hv. Frequency corresponds to a certain colour. And different frequencies produce the other colours. (I think I missed some things)

I considered that too you are not alone 😂 I think particulates is right j thought about it but thought they meant a group of emissions so that threw me
Yes I wrote the same but said strong line at red as absorbed from the red area visible light spec and at the highest frequency as from highest energy level
I thought for the mol and mass calculation questions they were asking the same question but then I read it carefully and it the same answer as people on here
