An atom has 8 protons, 8 neutrons, and 8 electrons. another isotope of the same element might have

It might have 10 neutrons

Reason: This is because an isotope of the same element must have the same number of electrons and protons so it can be assumed that the amount of neutrons can be changed.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
