One of the reactions that occurs in a blast furnace, in which iron ore is converted to cast iron, is fe2o3 + 3co → 2fe + 3co2 suppose that 1.19 × 103 kg of fe is obtained from a 1.90 × 103 kg sample of fe2o3. assuming that the reaction goes to completion, what is the percent purity of fe2o3 in the original sample?

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende
