A total of 2.00 of a compound is allowed to react with water in a foam coffee cup and the reaction produces 193 of solution. The reaction caused the temperature of the solution to rise from 21.0 to 24.7 . What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water.
A balloon filled with 2.50 moles of helium has a volume of 32.4 L. What will be the new volume if 5.90 moles are added under constant temperature and pressure?
