A 2.461-g sample of glutamic acid, C5H9NO4 (147.13 g/mol) was burned in a bomb calorimeter with

excess oxygen. The temperature of the calorimeter and the water before combustion was 23.76 °C; after
combustion the calorimeter and the water had a temperature of 29.46 °C. The calorimeter had a heat capacity of
660 J/K, and contained 1.405 kg of water. Use these data to calculate the molar heat of combustion (in kJ) of
glutamic acid
I got 2003 kj/mol (think its right)
Metallic Cd reacts with hydrochloric acid according to the following equation:
Cd (s) + 2 HCl (aq) → CdCl2 (aq) + H2 (g)
The enthalpy change associated with this reaction can be determined with an ice calorimeter. If 10.88 g of ice
are melted when 5.778 g of Cd reacts with excess hydrochloric acid, what is ∆H (in kJ/mol Cd) for the reaction
written above? The heat of fusion of ice is 333 J/g.
I got 70.5 Kj/mol (not sure about this one)
Alos my sig figs matter!
Thanks so much
