Question

3.
1.00 dm of ammonia gas is passed over heated copper(II) oxide.
3CuO(s) + 2NH3(g) + 3Cu(s) + N2(g) + 3H2O(1)
What is the volume of nitrogen formed when measured at the same temperature and pressure as
the ammonia?
A 0.25 dm
B
0.50 dm3
С
1.00 dm3
D 2.00 dm

Answer 1

Answer:

B

Explanation:

we can first convert volume into moles and then find moles of N2 by using mole ratio or directly find volume by using mole ratio.

mole ratio of NH3 : N2 = 2 : 1

hence volume of N2 would be 0.5 dm3
