From the data below, calculate the total heat (in J) needed to convert 0.333 mol of gaseous ethanol at 300°C and 1 atm to liquid ethanol (Molar mass = 46g/mol) at 25.0°C and 1 atm: bp at 1 atm: 78.5°C AH° vap 38.6 kJ/mol C gas 1.43 J/g.°C Ciquid , 2.45 J/g.°C. a. 197 b.-1970 c. 1970 d.19700 e.10700 ​

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).
