If ammonia is produced at a certain time, t, at a rate of 0.397 M/sec, what is the rate for each of the reactants

Calculate the energy required to ionize a hydrogen atom to an excited state where the electron is initially in the n = 5 energy level. report your answer in kilojoules

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

Δu of , in kj/kg, as it isto k, (a)as a of , (b) at , (c) at .
