The procedure that can be used to demonstrate that matter is conserved during a chemical change or reaction is called mass conservation. This involves measuring the mass of all the reactants before the reaction takes place and comparing it to the mass of the products after the reaction. If matter is conserved, the total mass of the reactants should be equal to the total mass of the products.
Remember to weigh any resulting gas :)
Yes, you are correct! When conducting the mass conservation procedure, it is important to account for any resulting gas that is released during the chemical reaction. This can be done by collecting the gas in a container and measuring its mass. By including the mass of the gas in the calculations, we can ensure that matter is fully accounted for and demonstrate conservation of mass. Thank you for mentioning that point!
