Question
1.The combustion of 1.32 g of ethanol was done inside the flask attached to the manometer shown below at 19.2 degrees Celsius. The diagram below shows the final mercury levels after the reaction was completed, where h= 35.5 mmHg. The atmospheric pressure is 782.1 mmHg. Assume that the water vapor pressure is 16.48 torr.
a. What volume in liters of carbon dioxide gas was produced?
b. If the gas was cooled evenfurther to 5.0 degrees celsius where it no longer acts as an ideal gas, what voume in liters would the carbon dioxide producec now occupy?
2. Balance the following redox reactions using the hald-reaction methods for (a) andcidic solution and (b) basic solution.
a. ClO^- (aq) + Cl^- (aq) = ClO3^- (aq) + Cl2 (g)
b. Ag (s) + CN^- + O2 (g) = Ag(CN)2^- (ag)
