amount of energy because it can not be created or destroyed.
The total number and type of atoms...........(apex:))
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.
The Law of Conservation of Matter states that matter can't be created or destroyed. When a chemical reaction happens, you aren't destroying the material you are simply changing it.
chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.
This is a balanced chemical reaction.
The new substances formed during a chemical reaction are called Products.
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.
Mass is conserved. This means it remains constant.
The Law of Conservation of Matter states that matter can't be created or destroyed. When a chemical reaction happens, you aren't destroying the material you are simply changing it.
Amount of energy because it can not be created or destroyed.
The total mass of the compounds remain constant.

A catalyst undergoes no chemical change during a chemical reaction.
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
A catalyst doesn't undergo a chemical change during a chemical reaction.
This chemical reaction is called dehydration.
This is a balanced chemical reaction.
D. always equal to the total mass of the products.
