I don't have questions but how the heck do you revise Organic?
I have exams in 6 days. Give me an advice on best way of revising :T_T:
Can you help me with my organic chemistry?
Haha, I'm going to give you some random questions:
1. What is the general formula of an alkene?
2. What are Esters isomers of?
3. How can you determine if an organic molecule is unsaturated?

1. CnH2n
2.the existence of two or more organic compounds(i.e alkanol and carboxylic acid)
3.when it contains carbon atoms joined by double or triple bond

OK here is something easy problems
1. put bismuth-209 through alpha decay
heres a basic stoichiometry problem-
2.How many moles of chlorine gas would react with 5 moles of sodium according
to the following chemical equation?
Na + Cl2 --> NaCl

1.
209, 83Bi -----> 205,81Ti + 4, 2He
2. five molecules of chlorine will react with 5 molecules of sodium to form sodium chloride according to the equation

This is an extra credit question i had on a worksheet that i didnt know how to do
The space shuttle environmental control system handles carbon dioxide (4% by mass exhaled air) by reacting it with Lithium Hydroxide pellets to form lithium carbonate and water. If there are 7 astronauts on board the shuttle, and each exhales 20 liters of air per minute, how long could clean air be generated if there were 25,000 g of lithium hydroxide pellets avaliable for each shuttle mission? Assume the density of air is 0.0010 g/mL.

yea geometry is not as easy as people say
are you any good with geometry?
