At 25 degrees Celsius the rate constant for the decomposition of a pesticide solution is 6.40e-3 min-1. If the starting concentration of pesticide is 0.0314M, what concentration will remain after 62.0min at 25 degrees Celsius
Plutonium, 244/94 PU, is a radioactive nuclide. When one of these atoms decays, a series of alpha and beta particle emissions occurs until the lead isotope, 208/82 Pb, is produced.
organic reactions can be classified as substitutions eliminations or additions and the reagents can be classified as
