A student needs to analyze an unknown sample to determine the percent composition of three compounds present in it. The student conducts a combustion reaction to determine the percent of carbon and hydrogen in the sample. The remaining residue is then dissolved in water and the solution is titrated with a standardized silver nitrate solution to determine the chloride ion concentration in the sample. Calculate the percent composition of each compound in the unknown sample using mass balance calculations.

A chemistry student is required to determine the cathodic and anodic Tafel slopes for a reaction occurring at an electrode surface. The current density at the cathodic surface is known to be 1.8 mA/cm² and the current density at the anodic surface is known to be 1.2 mA/cm². The current potential relationship is given by the Tafel equation:log (i) = log (i0) + β_c * (E-E_c) for cathodic reactionlog (i) = log (i0) + β_a * (E-E_a) for anodic reactionWhere i is the current density, i0 is the exchange current density, β_c and β_a are the cathodic and anodic Tafel slopes respectively, E is the elect
