Which of the following are conserved during a chemical reaction?
Size of reactants and products.
Volume of reactants and products
Number of atoms of elements in the reactants and products
Energy of the reactants and products
Mass of reactants and products
In a chemical reaction, the following are conserved:
1. Number of atoms of elements in the reactants and products: The total number of atoms remains constant in a balanced chemical equation.
2. Mass of reactants and products: According to the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction.
While energy can be transformed in a reaction, it isn’t strictly conserved in the same manner. The size and volume may change due to different states of matter, so they are not conserved as fixed quantities.
