A student mixes 10.0 g of Substance A with 15.0 g of Substance B and heats them until a chemical reaction
occurs. The student observes bubble formation and a color change. The product of the reaction weighs 21.0 g.
How is the reaction an example of the law of conservation of mass in action?
The gas that was produced during the bubble formation in the system (reaction) was
O converted back into reactants. This is what caused the mass of the reactants to be more
than the mass of the products.
The gas that was produced during the bubble formation in the system (reaction) was
O released into the surrounding environment. This is what caused the mass of the products
to be less than the mass of the reactants.
The gas that was produced during the color change formation in the system (reaction)
O was converted back into reactants. This is what caused the mass of the reactants to be
less than the mass of the products
