1. Aluminum has a specific heat of 0.902J/(g ∙ K) , how much heat is lost when a piece of aluminum with a mass of 28.372 g cools from a temperature of 429°C to 22.0°C.
2. A 500 g piece of iron (CP = 25.09 J/(mol · °C) changes 7°C when heat is added. How much heat energy produced this change in temperature?
3.When 300. cal of energy is lost from a 125 g object, the temperature decreases from 45.0°C to 40.0°C. What is the specific heat of this object?

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
