The laboratory compared the mass of the starting reactants and final products of the combustion reaction. A technician determined the mass of the firewood and oxygen reactants before burning to be 2.72 kg. After the firewood finished burning, the pile of cooled ash that remained had a mass of 0.095 kg. According to the law of conservation of mass, matter is neither created nor destroyed in a chemical reaction. Do the results of the technician’s combustion experiment contradict the law of conservation of mass?
