(: just had math tuition. wheee. and i finally figured out alot of things about alpha beta. so i hope i can get a1 for the a math test on tuesday? hahahaha. :D but about the maths supplementary lessons, 3z and 3n combined. AND THERE IS A WORLD OF DIFFERENCE BETWEEN THE CLASSES. and i really talk God for 3z. we make the world a livelier place. we had lessons in tmp and 3n sat on the right and 3z on the left. and the left side was so noisy. and fun. hahahha. 3z has all the fun people! (: okay. but that was from my point of view. :D HAHAHAHAHA.
yesterday the netballers had a friendly with united world college(uwc). but i didn't go. (: oh well. the show hanakimi is kinda overrated though. it's nice. but it's really far fetched. lol. oh well. :D
lets do a summary of the mole chapter here.
relative atomic mass = the mass of one atom of the element / the mass of 1/12 of an atom of carbon-12
relative molecular mass = the mass of one molecule of an element or compond / the mass of 1/12 of an atom of carbon-12
avogrado's constant is 6 x 10^23
number of moles = number of particles / avogrado's constant.
percentageby mass of an element in a compound = (Ar of element x number of atoms in formula / relativie molecular mass (Mr) of compound) x 100%
that's half the chapter that's going to be tested and I DO NOT UNDERSTAND A SINGLE WORD. like where's the link!?
it would be appropriate to have a panic attack right now.
