The energy content of food is typically determined using a bomb calorimeter. Consider the combustion of a $0.46-g$ sample of butter in a bomb calorimeter having a heat capacity of $2.67kJ/^{\circ }C.$ If the temperature of the calorimeter increases from $23.5^{\circ }C$ to $28.5^{\circ }C,$ calculate the energy of combustion per gram of butter. $Energy\quad of\quad combustion=\square kJ/g$

Which statement correctly describes a chemical reaction? Energy is always released. Bonds between atoms break and reform. Products go into a reaction. Reactants come out of a reaction.
