1. A 500 gram sample of hot mythril ore is submerged in a cold water bath. If the water experienced a change in heat of -58 kJ and the mythril ore experienced a temperature change of 4 kelvin, what must the specific heat capacity of the ore be? Have answer in units of J/g x degrees Celsius & show steps.
a. -0.43 J/g x degrees Celsius
b. -29 J/g x degrees Celsius
c. 0.029 J/g x degrees Celsius
d. 29 J/g x degrees Celsius
2. The following hypothetical circumstance takes place in a coffee-cup calorimeter. Dissolving 3 moles of a salt in 100 grams of water causes the temperature of the water to increase by 3 degrees Celsius. What is the enthalpy of this reaction? The specific heat capacity of water is 4.184 J/g x degrees Celsius
a. 1.255 kJ/mol
b. -225.9 kJ/mol
c. -0.4184 kJ/mol
d. -0.2259 kJ/mol
