Consider the reaction below. Fe2O3(s) + 3 CO(g) → 2 Fe(s) + 3 CO2(g)
The reaction of 165 g of Fe2O3 and 85.3 g of CO yields 72.1 g Fe. Find out the limiting reagent, theoretical yield, and percentage yield.

A0.10 m aqueous solution of sodium sulfate is a better conductor of electricity than a 0.10 m aqueous solution of sodium chloride. which of the following best explains this observation? (a) sodium sulfate is more soluble in water than sodium chloride. (b) sodium sulfate has a higher molar mass than sodium chloride. (c) to prepare a given volume of 0.10 m solution, the mass of sodium sulfate needed is more than twice the mass of sodium chloride needed. (d) more moles of ions are present in a given volume of 0.10 m sodium sulfate than in the same volume of 0.10 m sodium chloride. (e) the degree of dissociation of sodium sulfate in solution is significantly greater than that of sodium chloride.
