哇！好久没有来写blog了！！呵呵！不时为了读书哦！是为了。。。玩电脑游戏！哈哈！我看我是among那么多个stpm考生里最relax的吧！
好了！现在让我来温习一下吧！
Thermochemistry
1)enthalphy of formation
-the energy erquire/formed when 1 mole of compund is for from it's reactant in their state state!(mostly exothermic)
2)enthaphy of combustion
-the enegry released when one mole of compound is burn in excess of oxygen.
3)enthalphy of atomisation
-the energy require to form one mole of gaseous atom from it's element at their standard state
4)enthalphy of ionisation energy
-the enegry release when one mole of gaseous ion is form from it's atom.
5)
