ans is:d/all of the above as:The total mass of the system remains same in a chemical change. This is in accordance with the law of the conservation of mass. The total mass of products is equal to the total mass of the reactants. Sometimes substances (reactants) react to form a new substance (product), which in turn is able to form the original substance under certain conditions. This is a temporary change, but when reactants are permanently converted into new products, a chemical change takes place. Therefore, a chemical change is permanent and irreversible while the physical change is temporary and reversible.
