After adding the NaOH to the H2SO4 solution, the temperature of the mixture increases to 32.5°C. What type of reaction is occurring in the coffee cup?

547 J of thermal energy is added to a 200.0 g sample of iron that is initially at 68.0 °C. If the specific heat capacity of iron is 0.449 J/g°C, what will be the final temperature in °C?

A 1.720 g sample of naphthalene (C10H8) undergoes combustion in a bomb calorimeter, causing the temperature to rise from 24.00°C to 47.57°C. If the heat capacity of the calorimeter is 2940 J/°C, what is the enthalpy of combustion of naphthalene in kJ/mol?

A 100.0 mL sample of 0.300 M NaOH is mixed with a 100.0 mL sample of 0.300 M HNO3 in a coffee cup calorimeter. If both solutions were initially at 35.00°C and the temperature of the resulting solution was recorded as 37.00°C, determine the ΔH°rxn (in kJ/mol) for the neutralization reaction.

A 25.0 g piece of aluminum (which has a molar heat capacity of 24.03 J/mol °C) is heated to 85.1 °C and dropped into a calorimeter containing water (specific heat capacity of water is 4.18 J/g °C) initially at 25.0 °C. Assuming no heat is lost to the surroundings, what is the final temperature of the system?
