The equation for the ”thermite” reaction between aluminum and
iron(III)oxide is
2Al(s) + Fe2O3(s) → 2Fe(l) + Al2O3(s)
What mass of aluminum powder would be needed to react completely
with 16g of dried iron (III) oxide?

If Ammonium Nitrate (NH4NO3) is 35% Nitrogen, what is the mass of Nitrogen in 2.5 kg of NH4NO3?

2. The Tl in a 9.76-g sample of rodenticide was oxidized to the trivalent state and treated with an unmeasured excess of Mg/EDTA solution. The reaction is Tl3+ + MgY2- → TlY- + Mg2+
.Titration of the liberated Mg2+ required 13.34 mL of 0.03560 M EDTA. Calculate the % of Tl2SO4 (504.8 g/mol) in the sample.
