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 with this technique. (10[2])Peaks generated by this technique’s “differential scanning” (10[1])type indicate (-5[1])phase transitions. (-5[1])The equation [read slowly] “q equals C-sub-V times delta (10[1])T” can (10[1])be used with this technique to determine enthalpy change. (10[1])This technique can be performed with two nested Styrofoam cups (10[3])to determine (10[1])whether a process is exothermic (10[1]-5[1])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■
