A certain commercial process relies of the addition of NH4NO3 to a solution of their proprietary compound. The Chemist develops a plan to add 6.55 pounds of NH4NO3 to 14.0 gallons of water. The water in the factory is typically at an initial temperature of 18.0 degrees celsius and the temperature of the water cannot drop below 15 degrees celsius, or the reaction will be too slow. Will the above plan work? Use of the value of Delta H solution: +25.7 kJ/mol
Acrylonitrile, C3H3N (53.07 g/mol), is used in the synthesis of a variety of plastics. What mass of acrylonitrile can be produced from a mixtur.
