The repeating subunits that are responsible for the chance of a crystal are know as unit cells
heavy nuclei
light electrons
amorphous cells

Ineed ! i have no clue how to do this problem.

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.

What is the work done by the electric force to move a 1 c charge from a to b?
