Document Summary
Instructions: you have 75 minutes to complete this 100-point exam. Calculations, functional groups, forces and biochemicals show all work. Partial credit will be given for correct work. Label the phases, the critical point and the triple point: (10 pts) label solid, liquid and gas on the heating curve below. Heat added: (10 pts) circle and identify the functional groups in the molecules below. O: (10 pts) give the complimentary base pairing for the following nucleic acid sequences, aacccgguua, tggccaattc. 2 (15 pts) what is the pressure (in mmhg) of o2 gas produced by the decomposition of 1. 50 g of kclo3 in a 10. 0l vessel if the gas is measured at 25 c? (mm of kclo3 = 122. 55 g/mol) 2 kclo3 (cid:198) 2 kcl + 3 o2: (10 pts) a sealed can with an internal pressure of 721 mmhg at 25 c is thrown into an incinerator operating at 755 c.
