Question

Consider the reaction
2Al + 3CuSO4 = Al2(SO4)3 + 3Cu
What is the maximum amount of Cu (63.5
g/mol) that could be produced by reacting
20.0 grams of Al (27.0 g/mol) with excess
CuSO4?
1. 70.6 g
2. 57.2 g
3. 129 g
4. 31.4 g



Consider the reaction
4As + 3O2 = 2 As 2O3
What is the maximum amount of As2O3
which could be produced by reacting 10.0
grams of As with excess oxygen?
1. 13.2 g
2. 6.6 g
3. 26.4 g
4. 2 g
5. 5 g


For the reaction
4NH3 + 5O2 = 4NO + 6H2O
how much water (18.0 g/mol) can be pro-duced from the reaction of 37.1 g of ammonia (NH3 at 17.0 g/mol), with an excess of oxy-
gen?
Answer in units of g.

Laughing gas (nitrous oxide, N2O) is some-
times used as an anesthetic in dentistry. It is
produced when ammonium nitrate is decom-
posed according to the reaction
NH4NO3(s) = N2O(g) + 2H2O(§¤) .
How much water is produced if 43.5 g of
N2O is produced in this reaction?
Answer in units of g.

For the reaction
?P4 +? I2 !?PI3 ,
what is the maximum amount of PI3
(411.687 g/mol) which could be formed from
10.39 g of P4 (123.895 g/mol) and 16.17 g of
I2 (253.809 g/mol)?
Answer in units of g.
