What is the total of original and new substances that are the same after a chemical change?

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).

Which scientist showed that the total mass of the substances in a chemical reaction is always the same before and after the chemical reaction?
Antoine Lavoisier
When chemical change takes place the total number of atoms changes?
False.
What does not happen in a chemical reaction?
The total numbers of atoms of reactants do not change in products.
Why isn't a change in mass an indicator of chemical change?
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.
What is it called the total kinetic energy of the particles in a substance?
internal energy measures the total energy of the particles in a substance
Which observation does not indicate that a chemical reaction has occured?
Change in total mass of substances.
Do the total volumes of original and new substances stay the same after a chemical change?
It depends on the reaction. Often the volumes do change. For example, a gas could be formed when a liquid and a solid react.
What happens to mass when substances go through a chemical change?
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.
What type of change occurs when a new substance is formed that has different properties from the original substance?
when a substance undergoes a chemical change the original form cannot be recognized and it could get total new properties.
When substances go through a chemical change what happens to the mass'?
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.
In a chemical reaction the total mass of the substances before the reaction is?
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.
How does law of the conservation of mass apply to chemical reactions?
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.
Which scientist showed that the total mass of the substances in a chemical reaction is always the same before and after the chemical reaction?
Antoine Lavoisier
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
What will the mass be after the chemical change?
Total mass never changes.
What are advantage of chemical change?
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.
What happens to the total mass of substances during a chemical reaction?
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.
