The ionic equation was just balancing them

Topic that came up were 6 marker free radical asking i think to compare to different alkane and alkene. No sigma and pi bond. Some enthalphy changes. Simple electrolysis questions like what inorganic compound can be electrolised to get H and one geometric steroisorism. One question about skeleton formula to show butene and enthalphy change of formation and reaction

Yes. Standard enthalpy of reaction came out, What is standard temperature and standard pressure, the 6 marker was about alkanes and alkenes I can’t really remember much. Lol

Standard Temp is 298 K or 25 C and the Standard Pressure is 100 KPa

what do you think is going to be on physics and biology

Was there a question you know with the isomers where we have to draw in y or was that just empty because I think I missed a question

I think I did okay tbh I don’t know if I got the last question right tho

I think I wrote something like 6 and 2The 4 marker for enthalpy was so nice, I got 163 and the 6 marker was fine too. Just talked about electrophilic addition and free radical substitution.

The exam was okay but what do you think will come up on the physics

What do u guys say for the ionic equation

I think I wrote something like 6 and 2 which I just checked and got right.
The enthalpy 4 marker was so nice too. I got 163 and so did most ppl from my class
The 6 marker was fine. I think it was electrophilic addition and free radical substitution
The matching up of the standard conditions was easy. 100 kPa and 298K lol
I didn't like the isomer question tho.
