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? Explain your answer.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
