The following reaction can occur when a match is struck:
KClO3(s) + 3 P4(s) ------- > 3 P4O10(s) + 10 KCl(s)
(a) How many grams of KCl(s) can be produced from 38.56
milligrams of P4 assuming that we have a sufficient amount of KClO3
present?
(b) In a separate experiment, how many molecules of P4O10(s) can
be obtained from 0.00625 moles of KClO3? Assume we have a
sufficient amount of P4.
