Since it can be obtained in very high purity, benzoic acid is one of the classic materials used for determining the heat capacity of bomb calorimeters. the heat of combustion of benzoic acid, hc7h5o2 is -3227 kj mol-1. when 2.85 g of hc7h5o2 (molar mass = 122.12 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter changed from 24.05 ºc to 29.19 ºc. what is the heat capacity of the calorimeter in units of kj/ºc?

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential. because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential. request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts. ki k i = nothing ev request answerprovide feedback
