A metal oxide was placed in formic acid, HCO2H, and the solution heated under reflux for several hours. Recrystallization gave compound C. Thermogravimetric analysis (TGA) of C in air showed the following: Termperature, C 25 150 530 % mass 100.0 64.5 72.2 During the 1* event at 150 C, the waste gases were analysed. Two gases were identified. Their molar masses were 30 and 44 g mol-?. Identify C, and write a balanced equation for its formation. Write a balanced equation for the two events observed in the TGA experiment. [6 marks) A sample of C was also analysed using Differential Scanning Calorimetry, DSC. Sketch and describe the DSC data you would expect over the temperature range 40 - 600 C as the sample is (a) heated to 600 C (b) cooled after heating to 40C. (c) reheated to 600 C
