Question
Where stated, classify reactions both by the key reaction event (PPT, A/B, R/O) and by
changes in composition (COM, DEC, SDP, DDP).
5. _ Mg(N3)2(s) → _ M93N2(s) + _ N2(g)
balance, then classify:
-
Calculate the following, with proper number of significant figures:
When 0.057 moles of N2 form,
moles of Mg;N2 form also.
To make 92.0 moles of Mg3N2,
moles of Mg(N3)2 need to react.
To make 0.48 grams of N2,
moles of Mg(N3)2 need to react.
When 24.5 grams of Mg(N3)2 react,
grams of M93N2 are made.
To make a count of 5.62x1020 of Mg3N2 units,
grams of Mg(N3)2 need to react.
