Question #1.) An unknown liquid requires 7.72 kJ of energy tochange 12.4 grams 10.00 degrees C. Calculate the specific heat ofthe material.
Question #2.) Use the standard heats of formation from thetextbook to calculate delta H for the following reaction:
C6H12O6 + O2 (g) --> CO2 (g) + H2O (g)
Question #3.) Calculate the standard enthalpy of formation ofsolid Ca(OH)2, given the following data:
Ca(s) + O2(g) + H2(g) --> Ca(OH)2
2Ca(s) + O2(g) --> 2CaO(s)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â H= -848.6 kJ
2 Ca(OH)2 (s) --> 2 CaO (s) + H2O (l)Â Â Â H =+92.2 kJ
H2 + 1/2 O2 --> H2O(l)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â H = -236 kJ
