Round 9: Tossup 20

A “power-compensated” form of this technique uses negative feedback to maintain isothermal sample and reference crucibles. A method for determining ligand binding affinities combines titration (10[1])with this technique. (10[1])Peaks generated by this technique’s “differential scanning” type indicate (10[1])phase transitions. (-5[3])The equation [read slowly] “q equals (-5[1])C-sub-V (-5[1])times delta T” can be used with this technique to determine enthalpy change. (10[1])This technique can be performed with two nested Styrofoam cups (10[2])to determine whether (10[1])a process (10[1])is (10[1])exothermic or endothermic. For 10 points, identify this technique whose “bomb” type can be used to measure the heat (10[1])flows associated with a chemical reaction. (10[1])■END■ (10[1])
