GUYS

has anyone got a list of all the catalysts in C1?
Original post by lilyhutton
how did you come up with that wow
for the limestone vs concrete one, what would be some advantages of limestone? can only come up with disadvantages and advantages of concrete. thanks

good luck everybody!

Made up the questions while sitting on a computer desk and doing some research to make it seem a tad plausible.
Easy to cut
More attractive
Natural resource so no need to process.

Phosphoric acid - Hydration of ethene
Yeast + 37oc - Fermentation of sugar to make ethanol

Lolololol no, just a practice paper made by the talented Palette


I am honoured and amused at the same time that people believe AQA will include a question featuring a drug trafficker in the actual exam... and think my paper is the real paper even though I explictly wrote 'Hoax Paper' at the top!
I already have butterflies in my stomach and we've still got about an hour. I hate waiting. I'd rather get the exam over and done with.

Waiting is the worst, especially when its a weekend before the exam that just kills!

What is nickel used for (to catalyse)????
Just wanted to let everyone know that you dont need GCSEs if you have swag. Just remember that swag overrules everything in later life. Take mugging an old lady over a pass in C1 anyday to achieve your full potential. Also if you're reading this before you've started your GCSE's I'd highly recommend taking the COPE course because being personally effective is a life skill only decendents of Coutts can conquer.

Thankyou but how does it happen??

When ethene and hydrogen are heated together in the presence of a nickel catalyst a reaction takes place which removes the double carbon carbon bonds to produce ethane. This process is called hydrogenation.
