Problem 97

In most of its ionic compounds, cobalt is either Co(II) or Co(III).One such compound, containing chloride ion and waters of hydration,was analyzed, and the following results were obtained.A 0.256-g sample of the compound was dissolved in water, andexcess silver nitrate was added. The silver chloride was filtered,dried, and weighed, and it had a mass of 0.308 g. A second sampleof 0.416 g of the compound was dissolved in water, and anexcess of sodium hydroxide was added. The hydroxide salt wasfiltered and heated in a flame, forming cobalt(III) oxide. Themass of cobalt(III) oxide formed was 0.145 g.a. What is the percent composition, by mass, of the compound?b. Assuming the compound contains one cobalt atom per formulaunit, what is the molecular formula?c. Write balanced equations for the three reactions described.

Chapter 16 Notes – Chemical Equilibrium 16.1 – Fetal hemoglobin and equilibrium  Equilibrium constant (K) – describes the concentrations of the reactants and products in a reaction at equilibrium o Large K – products favored o Small K – reactants favored  Systems at equilibrium respond to changes in ways that maintain equilibrium. If concentrations of the reactants or products change, the reaction shifts to counteract that change  Hemoglobin binds oxygen when the surrounding oxygen concentration is high, but it releases oxygen when the surrounding oxygen concentration is low 16.2 – The concept of dynamic equilibrium  Reversible – describes a reaction that can proceed in both the forward and rev
