Air bags in cars operate according to the decomposition reaction below. 2 Na3N) ► 6 Na(s) + N2(8)
a. Use stoichiometric calculations to determine how many grams of nitrogen
gas are produces during the decomposition of 6.22 g Na3N?
b. Use stoichiometric calculations to determine how many grams of sodium
are produced during the decomposition of 6.22 g Na3N?
c. Use your finding from parts a. and b. to confirm that mass is conserved in
chemical reactions.
d. Calculate the mass percent of each element in a pure sample of Na3N.
e. Use your finding from parts a., b. and d. to confirm the law of definite
proportions by showing that the mass percent of each element in Na3N is
equal to the mass percent of each species after the compound has
decomposed.
