and we tried desperately to 'girl-ise' audrey....
no use though... =P
we had chemistry lab today....was kinda scary....dr lee started out u lecturing us on safety precautions and kept on warning us about breaking thermometers...she said if we break it we clean it up ourselves... @.@
chemical equation of the day:
Mg + 2HCl = MgCl2 + H2
first we took 0.65g of Mg powder and 50cm3 of HCl and mix it together...then.....psssssst!
Heat energy!! lots of steam coming out of the cup! very cool! ^^
that was mostly it..after that, the temperature was taken every 30 seconds for the next 5 minutes, then we had to draw a graph and do calculations and stuff....
