Sulfur burns in the presence of oxygen to produce sulfur dioxide. Explain how the mass of sulfur dioxide produced compares to the combined mass of sulfur and oxygen.
What does the law of conservation of mass indicate?
Is this on the right track?.....mass cannot be created/destroyed, although it may be rearranged in space, and changed into different types of particles. This implies that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products.
