The complete combustion of 0.459 g of benzoic acid, C7H6O2 (AH°C= -3230 kJ mol-1) in a bomb
calorimeter causes the temperature to rise by
1.17°C. The complete combustion of 1.705 g of
glucose, C6H12O6 in the same calorimeter causes a
temperature rise of 2.57°C.
Determine the heat capacity of the calorimeter.​

Which of the following observations indicates that there is a small, dense, positively charged part in the center of an atom? some uncharged particles are scattered by a gold foil. all uncharged particles are attracted towards a gold foil. all positively charged particles pass straight through a gold foil. some positively charged particles bounce back from a gold foil.
