The toxic pigment called white lead, Pb₃(OH)₂(CO₃)₂, has been replaced in white paints by rutile, TiO₂. How much rutile (in grams) can be prepared from 379 g of an ore that contains 88.3% ilmenite (FeTiO₃) by mass? The reaction is:
2 FeTiO₃ + 4 HCl + Cl₂ → 2 FeCl₃ + 2 TiO₂ + 2 H₂O
What is the limiting reactant in a reaction that produces sodium chloride from 8 g of sodium and 8 g of diatomic chlorine?
