Final answer:
Mass is the property of matter that is conserved in chemical reactions and shown by balanced equations.
Step-by-step explanation:
The property of matter that is conserved in chemical reactions and shown by balanced equations is mass In a chemical reaction, the law of conservation of mass states that the total mass of substances taking part in the reaction remains constant. This means that the mass of the reactants is equal to the mass of the products. For example, if you have 10 grams of reactants, the total mass of the products after the reaction will still be 10 grams.
