Chemistry Cramming

eoins2345

Hey i trying to as well as can in chemistry to make up for maths so how should i divide up my time between now and tuesday?

Fringe

Organic chemistry. It's a good one to cram. So much in it.
Also, titrations and organic experiments too.

Then there's the other questions. Atomic theory/periodic table is usually Q5. Equillibrium comes up quite often. I'd also do a bit on Rates of Reaction.

cheers fringe im in the same situation ill have saturday to monday and all tuesday morning to cram so i should do ok hoping for C1 B3 area

hey eoin don't worry about chemistry is a subject that you can really learn quickly i got 88 % in the mocks and i would recommend the following :

Q1: Know the bleach titration and the iron tablets-v-KMnO4 really well.
Q2: Ethene and ethyne and saponification
Q3: I wouldnt bother it takes too long.
Q4: Study the main definitions this shud b an easy enuf q to get ur marks
Q5: Ionisation energy
Q6:Learn how to do heat of combustion calculation look at 2006!
Q7: Water hardness and watnot

Learn free radical substitution it will save ur life

The following are all guaranteed questions:

- Organic chemistry (the easiest section in my opinion, and three questions out of eight if you cover it well)
- Atomic theory (question 5. There's not a lot to cover here!)
- Rates of Reactions (will show up as either question 3 or a part b question. Again, there isn't a huge amount to cover...only 4 or 5 things they can ask really...)
- Titrations (question 1. Always the easiest question on the paper... They ask the same stuff every year really. Practice the calculations)

These are the most important areas, and they'll cover you for a lot of short questions. Don't bother with the experiments apart from organic, titrations and rates. No point really!

Other topics can probably be left out but do try and glance over them if you've covered the main areas, eg. equilibrium, stoichiometry, radioactivity, industrial and atmospheric chem, oxidation and reduction, gases etc.

Good luck!

Oh yeah, forgot to mention... The best way to study for chem is to revise a section, learn the definitions etc and then do out 2 or 3 questions on that section from the papers with the book closed. You'll improve a lot if you do it that way!

1fahy4 pretty much hit the nail on the head there. Know all that and you're good to go!

Yay!! Leaving Cert will soon be over!! Chemistry is my last exam. Any predictions???

marblesolutions

These are my predictions for what they are worth
Ethanal prep
Bleach or iron tablet titration
anion tests
prep of ethene and ethyne
Ionisation energy/electronegativity/bonding
Diag. for dis.of crude oil
Equil. experiments and Kc
diag for acid bases
The usual stuff after that
