Round 7: 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 with this technique. (10[1])Peaks generated by this technique’s “differential scanning” (-5[1])type indicate phase transitions. The equation [read slowly] “q equals C-sub-V times (10[1])delta T” can be used with this technique (10[2])to (10[1])determine (10[1])enthalpy change. This technique can be performed with two nested (10[1])Styrofoam cups (10[1])to determine (10[1])whether a process is exothermic or endothermic. For 10 points, identify this technique whose “bomb” type can be used to measure the heat flows associated with a chemical reaction. ■END■
