Document Summary
Instructions: you have 50 minutes to complete this 100-point exam. D: compounds with identical molecular formulas, but whose molecules have different structures are called: Calculations, functional groups, forces and biochemicals show all work. Partial credit will be given for correct work. If i cannot read the work, it will not be graded: (5 pts) a gas collected over water had a total pressure of 725 torr. Calculate the partial pressure of the gas (in torr) if the temperature was. Label the phases, the critical point and the triple point: (20 pts) circle and identify the functional groups in the two molecules below. O: (10 pts) give the complimentary base pairing for the following nucleic acid sequences. O: aggcct, ucaaag (15 pts) what volume (in l) of gaseous ph3 at 1. 00 atm and 20 c could be formed by the reaction of 100. g of calcium phosphide with excess water? (mm of ca3p2 = 182. 18 g/mol)
