A chemical reaction occurs in a test tube. The mass of the reactants and test tube is 23g before the reaction occurs. During the reaction a gas is formed and the reaction bubbles vigorously the gas escapes into the air after the reaction, the mass of the products and test tube is 22g
Does the law of conservation of mass apply to this reaction?
Yes, the law of conservation of mass applies to this reaction. The total mass of the reactants and test tube before the reaction is 23g, and the total mass of the products and test tube after the reaction is 22g. This difference in mass can be accounted for by the gas that escaped into the air during the reaction. The mass of the gas that escaped is not included in the total mass after the reaction, but it was still a part of the system and was accounted for in the total mass before the reaction. Overall, the total mass before and after the reaction remains the same, demonstrating the conservation of mass.
