Anyway,, im studying for tomm's Science practical igcse. Just so u know we tried our last practice and it was putting some i think copper to some acid or sumthing like the sort and burn it to the bunsen burner,, it first turned green and i thought oh pretty,, then it gives out small bubbles and it grew into bigger bubbles,, suddenly the shit blew up and spat acid all over my wrist,,, it felt like normal water,, then it got hotter and it itches! Crap i hate this subject..
Some formulas are followed (word formulas, i still dk the symbols even though it's required):
Carbonate when mixed with dilute acid produce white precipitate
Chloride when acidify with dilute nitric acid then add aqueous silver nitrate will produce white precipitate.
Nitrate when add aqeuous sodium hydroxide then aluminium foil then warn carefully gives out ammonia (wtvr that is..)
Sulphate when acidify then add aqeous barium chloride/aqueous barium nitrate gives out white precipitate.
That's only one third of it! How am i suppose to memorize all this??????? HELP!!!
Cobra Starship's new song : Good Girl Go Bad feat. Leighton Meister is the shit! Listen to it here.
