Question 3 (4 points)

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

> 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 answer is barium and copper bromide
