The production capacity for acrylonitrile (C3H3N) in the United States is over 2 billion pounds per year. Acrylonitrile, the building block for polyacrylonitrile fibers and a variety of plastics, is produced from a gaseous propylene, ammonia, and oxygen:
2 C3H6(g) + 2NH3(g) + 3 O2(g) 2C3H3N(g) + 6H2O(g)calculate the massCalculate the mass (in grams) of each rectant after the reaction is complete:
carbonic acid solution with [H_2CO_3] = 0.00735 M is titrated with 0.100 M KOH. Determine the pH of the solution when 70.00mL of OH have been added.
An environmental engineer analyzes a sample of air contaminated with sulfur dioxide. To a 500. mL sample of air at 700. torr and 38°C, she adds 20.00 mL of 0.01017 M aqueous iodine, which reacts as follows:
