manganese is extracted from the alloy and converted to the purple manganate (VII) ion (MnO.). This is thes A good example of this is the determination of the percentage of manganese present in a steel sample. The made to react with excess hydrochloric acid according to Reaction I. Reaction I 104. 2MnO, +16H+10CI 2Mn + 5Cl(g) + 8H₂O Since the temperature of the system is known, the ideal gas equation can now be used to calculate the number of The chlorine gas thus produced is collected in a container and the pressure and volume of the gas is determined moles of chlorine gas present. From this value, the number of moles of manganese can then be determined. How can the ideal gas equation be rearranged to allow for the determination of n? 102. A n = PV/(RT) B n = RT/(PV) PV=nXR1 QUE ART C n=PT/(RV) D n= RV/(PT) gas equation Questions 102-104 Sometimes, one may need to know the number of moles of a substance present. This can be efficiently done by and the stoichiometry of the reaction, one could then determine the number of moles of gas present and hen reacting the substance with a reagent which would lead to the production of a gas. Using the ideal p the number of moles of the substance present. 103. What would be the approximate ratio between the mass of manganese in the steel sample and the mass of chlorine gas produced? (Approx. atomic weights: Mn = 55 g/mol; Cl = 35.5 g/mol) 2:5 3:2 C 3:4 D 1:3 A B C D A B S-2X2 Reaction I is endothermic and hence the actual temperature of the reaction vessel may be different from that expected. Given that the initial temperature of the reaction vessel was used in the calculations, how would this affect the predicted value of n? It would be greater than the actual value. It would be less than the actual value. It would be the same as the actual value. This cannot be determined from the information given. TE C
