Chem notes pt 1 Compunds and elements and blah blah blah.. @ 7:44 PM
haha here are the chemistry notes i made up for elements etc. ermm, they are basically a summary of the chem notes that Mr Wong gave us. So, i shortened them and now i present to u.... MY VERY FIRST NOTE OF THE SET OF NOTES IM GONNA PUBLISH.....
Lol... btw... errm, i've decided to leave out diffusion, kinetic theory... cos i think u guys alrd memorise and noe liao:D
Haha, also pls rmb wad mr wong said... to answer heating curve qns... there are 3 things u need to write down....
1. Arrangement
2. Action
3. Aftermath
Haha LOL the 3As :D
ok, lets begin...
Elements
Properties of Compounds
Ok?? Haha, pls give me feedback on these ntes, whether they need to be more specific or anything else
*PS errm, my ntes are based on the sch's ntes.... Also, my ntes only consist of wad i think u guys will need to revise... for the whole thing... go see the ntes or find Mr Wong to clear ur doubts :)))
And, also, JIAYOUS for ur revision!!!! :)

Elements
- substance that cannot be broke down into simpler substances
- each element has a name & symbol
- E.g. Copper (Cu), Sulfur (S), Oxygen (O)
- pure, have fixed boiling and melting points
- can be classified into metals & non-metals
- atoms joined in grps
- diatomic molecule= 2 of the same atoms joined together
- E.g. oxygen gas (o2)
- substance that contains 2 or more diffrent elements which are chemically combined through chemical reactions
- joined together by chemical bonds
- E.g. water, salt, sugar...
- Combustion
- Combination
- Decomposition of compounds
- Reacting elements and compounds
Properties of Compounds
- heat and/or light may be released or absorbed during chemical reaction
- properties of compound are diff. from properties of constituent elements
- have a fixed proportion of its constituents by mass
- pure
- can be broken down into constituents by chemical methods
- 2 or more diff. substances that are mixed together & are not chemically combined
- Impure
- Constituents retain own properties
- can be seperated into constituent substances by simple physical methods
