The specific heat of water and steam (water vapor) are 4.18 J/g C and 2.10 J/g C respectively. Heating a 74.0 g sample of water from 88.3 C to water vapor at 112.5 C requires 172.58 kJ of heat. Calculate the heat of vaporization of water in kJ/g. Assume the boiling point of water is 100 C

How many atoms of oxygen are contained in 160 grams of n2o3

Acylinder is filled with 2.00 moles of nitrogen, 3.00 moles of argon and 5.00 moles of helium. if the gas mixture is at stp, what is the partial pressure of the argon

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).
