In a neutralization reaction, an acid and a base are reacted to form salt and water. A student measures carefully how much of each reactant he used: 40.0 g of the base and 36.5 g of the acid. He then measured his products and found that he had made 51.7 g of salt and 12.4 g of water. Has the student demonstrated that the Law of Conservation of Mass works? Explain in detail how you know that the law has or has not been demonstrated to work in this experiment...
