In the second footnote it was pointed out that mass and energy are alternate aspects of a single entity called mass-energy. the relationship between these two physical quantities is einstein's equation, e= mc^2, where e is energy, m is mass, and c is the speed of light. in a combustion experiment, it was found that 12.096 g of hydrogen molecules combined with 96.000 g of oxygen molecules to form water and released 1.715 x 10^3 kj of heat. use einstein's equation to calculate the corresponding mass change in this process, and comment on whether or not the law of conservation of mass holds for ordinary chemical processes.
