Compare the movement and arrangement of the molecules in solid nitrogen to those in nitrogen gas.

Nitrogen molecules in solid nitrogen would vibrate about fixed positions close together in the regular lattice and have weak intermolecular forces holding the molecules together. However, in nitrogen gas the nitrogen molecules would be traveling in random directions at high speed and far apart.

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

> 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.
