It would be called a physical change, and would not be a chemical change at all. In order for a chemical change to occur, the original substances (reactants) must have different physical and chemical properties than the new substances (products).
Another substance is obtained.
mass
Antoine Lavoisier
False.
The total numbers of atoms of reactants do not change in products.
A change in mass is not always an indicator of a chemical change because mass is conserved in chemical reactions. The total mass of the reactants is equal to the total mass of the products. However, there are some exceptions where a change in mass can occur due to the release or absorption of gases or changes in the physical state (such as evaporation or condensation) during a chemical reaction.
internal energy measures the total energy of the particles in a substance
Change in total mass of substances.
It depends on the reaction. Often the volumes do change. For example, a gas could be formed when a liquid and a solid react.
The total mass of products is unchanged from the total mass of the reactants, but the masses of particular substances among the reactants or products change.
when a substance undergoes a chemical change the original form cannot be recognized and it could get total new properties.
The total mass of products is unchanged from the total mass of the reactants, but the masses of particular substances among the reactants or products change.
The mass of all substances before a chemical reaction is equal to the mass of the substance after the reaction. This is under the law of conservation of mass.
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
Antoine Lavoisier
A catalyst undergoes no chemical change during a chemical reaction.
Total mass never changes.
The biggest advantage of chemical change is life. All organisms are alive because of the sum total of all the chemical reactions occurring in their cells.
During a chemical change,chemical energy may be changed to other forms of energy.other forms of energy may also be changed to a chemical energy.
