im gonna fking dieeehahaha RIP engima. Wed, Thu and Friday you have exams!
Biology and 4u
It wasn't bad
5 exams in the space of 7 days
and yeah coz you do 4 unit, that's barely fair (((((((

No you are right. I should structure. Thanks.Mostly correct stuff but the setting out should be improved on. The question starts by asking about the differences in structure so that's what you should begin with.
Oxygen is a non-polar molecule with a linear structure, with one double O=O covalent bond.
Ozone is a polar molecule which gives it its bent structure. It contains a coordinate covalent bond (O=O-O you should draw the molecules).
Then it asks for two differences in their properties:
Ozone's higher molar mass (3 Oxygen molecules instead of 2), means it has increased dispersion forces acting on it which gives it higher boiling and melting points than Oxygen.
Since Ozone is polar, it also has strong dipole-dipole forces between molecules , which makes it more soluble in water (also a polar molecule) than oxygen which is non-polar.
Other properties you could include:
Ozone is more reactive and is a stronger oxidising agent, which is due to its unstable structure.
Ozone is more easily decomposed than oxygen which is very stable. This is also due to ozone's unstable structure.
Hope this helps
Someone please correct me if I made any mistakes.
Make sure you structure well, sometimes a lot of marks are dependent purely on how you structured your answer.No you are right. I should structure. Thanks.
Yes Thanks.Make sure you structure well, sometimes a lot of marks are dependent purely on how you structured your answer.
hahah that is not something I would like! You'll be fine!im gonna fking dieee

You'll be fine.
Thanks!! Ikr lol but then again, 2u maffs and business are barely subjects hahah!hahah that is not something I would like! You'll be fine!
The beauty of doing 4u maths, 2 other units are english leaving you with 4 more units (2 subjects).
All i have left is bio, chem and math exams hahahah
A combination question which tests on the integration of knowledge across different modules7 marker? What's it going to be guys?
All chemicals used in the experiment are toxicwhy do we use fume cupboard in bromine experiment?
not sure if because bromine toxic + release vapours or if cyclohexene/ane toxic + release vapours or both :/
oooA combination question which tests on the integration of knowledge across different modules
cyclohexane/ene release toxic fumeswhy do we use fume cupboard in bromine experiment?
not sure if because bromine toxic + release vapours or if cyclohexene/ane toxic + release vapours or both :/
what about vapour?All chemicals used in the experiment are toxic
what about bromine?cyclohexane/ene release toxic fumes
what about bromine?
what about vapour?
cyclohexane/ene release toxic fumes
.All chemicals used in the experiment are toxic
Yes the cyclohexene, cyclohexane and bromine water solution are all toxic if they were to be inhaled and may cause irritation/burns when coming in contact with the skin.what about bromine?
which oneyup no one answered my q yet
