  • Enthalpy of Solution, Hsoln
    The enthalpy of solution , enthalpy of dissolution , or heat of solution is the enthalpy change associated with the dissolution of a subst...
  • Enthalpy of Sublimation, Hsubl
    The heat (or enthalpy) of sublimation is the amount of energy that must be added to a solid at constant pressure in order to turn it direct...
  • Enthalpy of Combustion, ∆Hc
    • The heat released   when 1 mole of substance is burned completely in excess oxygen.     C (s) +   O 2(g)    → CO 2(g)                  ∆ ...

about our team

asalamualikum and very good morning to all readers...

thermochemistry of h24...
Mohamad Kuzahier
my name is mohamad kuzahier bin mohd zahari ...i am the group leader of this team....first of all. let me introduce my group member,,
Siti Nurfatihah
Nur Atiqah
Nur Sara Athirah
The first group member is,   nur sara athirah, then we have siti nurfatihah and last but not least is atiqah....
we, students from H24 KMJ will present you all about thermochemistry...
in this blog...we will present for you all about chapter 9 in chemistry for matriculation student...
so we will share with you whatever knowledge that we have....so we can increase our understanding of this chapter..have fun guys!!.keep it in mind that...chemistry is cool...




Above are our pictures...
we are whacky, cute and fun to be with....
for interesting students like us, for sure we have an interesting lecturer too..
wondering who is our lecturer???????
 she is.........................................
