The molar heat capacity of iron (M = 55.8) is 25.1 J/K•mol. How much energy must be added to increase the temperature of 111.6 g of iron by 10 K?




How much energy does an aluminum (M = 27.0) sample gain if its molar heat capacity is 24.2 J/mol•K, its mass is 13.5 g, and it is heated from 10.0°C to 40.0°C?








The enthalpy of formation of a compound is 612 kJ/mol, and the products of its combustion have a total enthalpy of formation of 671 kJ. What is the enthalpy of combustion of this compound?




What is the value of ∆G at 250 K for a reaction in which ∆H = 185 kJ/mol and ∆S = +2.00 kJ/mol•K?
