Bomb calorimetry provides precise amounts of energy a person derives from the foods consumed. c. The amount of carbon dioxide consumed gives an indirect measure of energy released. d. A bomb calorimeter measures the amount of oxygen released when a food is oxidized. e. In general, the fuel value of protein foods will exceed their energy value as measured by bomb calorimetry.

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
