1. Upon heating, NaN3(s) decomposes to Na(l) and N2(g). This reaction serves as a convenient laboratory preparation of pure nitrogen gas.
2 NaN3(s) ¾® 2 Na(l) + 3 N2(g)
a) What number of moles of NaN3 is required to prepare 1.00 mol of N2?
b) What mass of N2 is produced by the decomposition of 2.00 mol NaN3? (
c) What mass of Na is produced when 1.75 g of N2 is prepared?
We have given the reaction:
a.) 3 moles of gives 2 moles of
1 mole of moles of
b.) 2 moles of gives 1 mole of
1 mole of give moles of
c.) Similarly we can also this part also.
