Nitrobenzene (C6H5NO2) is used in small quantities as a flavoring agent or in perfumes but can be toxic in large amounts. It is produced by reaction of benzene (C6H6) with nitric acid:C6H6(l) + HNO3(aq) → C6H5NO2(l) + H2O(l)Calculate the theoretical yield for this reaction.

The reaction between solid aluminum and iron (III) oxide can generate temperatures reaching 3000 ºC and is used in welding metals. 

2 Al + Fe₂O₃ → Al₂O_­3 + 2 Fe

If 150 g of Al are reacted with 432 g of Fe­₂O₃, what is the mass of the excess reactant remaining? 

Acrylonitrile (C­₃H₃N) is the starting material for many synthetic carpets and fabrics. It is produced by the following reaction: 

2 C₃H₆ (g) + 2 NH₃ (g) + 3 O₂ (g)  → 2 C₃H₃N (g) + 6 H₂O (g)

If 12.0 g C₃H₆, 10.0 g NH­₃, and 5.0 g O₂ react, what mass of acrylonitrile can be produced, assuming 100% yield?
