These mystery elements are at the top of their families on the periodic table. An element that is in the same family as element is likely to have which properties? A) Two valence electrons, solid, metal

B) Six valence electrons, gas, nonmetal

C) Six valence electrons, solid, nonmetal

D) Two valence electrons, solid, nonmetal

> 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.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
