What is always true, according to the law of conservation of matter
According to the law of conservation of matter, matter can neither be created nor destroyed in a chemical reaction. Therefore, the total mass of the reactants must always be equal to the total mass of the products. In other words, matter is always conserved in any chemical process, regardless of the changes it undergoes.
According to the law of conservation of matter, the total amount of matter in a closed system is always conserved. This means that matter cannot be created or destroyed; it can only change form or be transferred between objects. So, the statement that is always true according to this law is that the total mass of a closed system remains constant over time.
According to the law of conservation of matter, the total amount of matter in a closed system remains constant over time. This means that matter cannot be created or destroyed; it can only change forms or be rearranged. In other words, the mass of the substances involved in a chemical reaction before the reaction occurs will be equal to the mass of the substances after the reaction has taken place.
To understand why this is always true, we need to consider the fundamental principles of atoms and molecules. All matter is made up of tiny particles called atoms, which combine to form molecules. In a chemical reaction, the atoms and molecules rearrange themselves, but the total number of atoms remains the same. This means that the total mass of the substances involved must also remain constant.
To verify this law in practice, we can perform experiments where we measure the mass of reactants before a reaction and the mass of products after the reaction. By comparing these masses, we can confirm that the total mass has not changed, thereby demonstrating the law of conservation of matter.
