Tris (short for tris-(hydroxymethyl)aminomethane) is a commonly used buffer for biochemical solutions. a. True
b. False

> 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 c.the valence of the atoms combine .
