How do you solve this?
Question 5 (1 point) In order to calibrate a constant volume bomb calorimeter, the combustion of (7.9100x10^-1) g of benzoic acid, CoH5COOH, was observed to cause the temperature in the calorimeter to rise from 25.000 to (2.973x10^1) °C. The energy. of combustion of benzoic acid, AU, is -3226.7 kJ mol-1. What is total heat capacity (C) of the calorimeter (including all its contents) in kJ °C-1? Pay attention to significant figures, keeping in mind that...

Nitrogen is sometimes diffused into the surface of a steel component in a process called case hardening. Consider a sheet of steel (1.416x10A0) mm thick which has nitrogen atmospheres on both sides at a temperature of 1200°C. The system is permitted to achieve a steady-state diffusion condition. The diffusion coefficient for nitrogen in steel at this temperature is (6.735x10A-11) m2/s. The diffusion flux is found to be (2.52x10A-7) kg/m2-s. It is also known that the concentration of nitrogen at the...
