5. What is the net ionic equation for the reaction that occurs if we mix aqueous solutions of Pb(NO,), and RbOH? A) Pb(NO:),(aq) + 2RBOH(aq) → Pb(OH)) + 2RÜNO:(aq) B) Pb*"(aq) + 20H(aq) → Pb(OH){s) C) Pb?"(ag) + 2NO, (aq) +2Rb*(aq)+20H (aq) → Pb"(a) + 20H (e)+2Rb'tag) +2NO, (a) D) Pb (aq) + 20H (aq) → Pb(OH);(aq) E) Pb* (ag) + 2 NO,7(og) + 2Rb*(aq) + 20H (ag) → Pb(OH):(s) + 2Rb*(=q} + 2NO, (ag) 6. Element X is not among the elements explicitly mentioned in the rules on oxidation states. What is the number of I atoms in the formula XOI, , if the oxidation state of X is +3? A) 2 B) 4 C) 5 D) 3 E) 1 7. A sample of CC, gas is mixed with another gas (A) of unknown molar mass. There are equal numbers of molecules of each gas in a low pressure chamber. The gases are allowed to effuse through a pinhole, and it is found that gas A escapes at 0.7785 times the rate of CC4. The molar mass of gas A is: A) 136 g/mol B) 174 g/mol C) 198 g/mol D) 126 g/mol E) 254 g/mol 8. The enthalpy of combustion of heptanoic acid is -31.83 kJ/g. Combustion of 3.85 g of heptanoic acid causes a temperature rise of 2.96°C in a certain bomb calorimeter. What is the heat capacity of this bomb calorimeter? A) 41.4 kJ/°C B) 6.90 kJ/°C C) 363 kJ/°C D) 0.358 kJ/°C E) 123 kJ/°C
