Consider the accompanying diagram. Ball A is allowed to fall and strike ball B. Assume that all of ball A's energy is transferred to ball B, at point I, and that there is no loss of energy to other sources. What is the kinetic energy and the potential energy of ball B at point II? The potential energy is given by PE mgz, where m is the mass in kilograms, g is the gravitational constant (9.81 m/s2), and z is the distance in meters.
the rate of flow to an ammonia synthesis reactor contains 25 mole ltbrgtnitrogen and the balance hydrogen. the flow
U-235 undergoes many different fission reactions. For one such reaction, when U-235 is struck with a neutron, Ce-144 and Sr-90 are produced along with some neutrons and electrons.
Use the masses given in the following table to calculate the change in energy when 1 mol of 232Pu nuclei and 1 mol of 231Pa nuclei are each formed from their respective number of protons and neutrons.
Calculate the stoichiometric reactant ratio (mol H2 react/mol C2H2 react) and the yield ratio (k mol C2H6 formed/k mol H2 react).
A mixture containing 98 mol% methanol and 2 mol% of an inert contaminant is available as a feed to a formaldehyde plant. The fresh feed to a process consists of 1000 kmol/h of this mixture along with 200 kmol/h of oxygen. All of the oxygen is consume..
Tris (pentafluorophenyl) borane, commonly known by its acronym BARF, is frequently used to initiate polymerization of ethylene or propylene in the presence of a catalytic transition metal compound.
