oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

> 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.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
