are these endothermic or exothermic?
2H2O2 (l) �¨ 2H2O(l) + O2(g)
∆H = -190 kj
C(s) + H2O (g) �¨ CO (g) + H2 (g)
∆H = +113
A negative delta H means the heat is given up by the reaction. A + delta H means the heat is added to the reaction.

to this, the first reaction is exothermic and the second reaction is endothermic.
