False
No.
In a chemical change, atoms are combined or separated, but the mass of each atom stays the same, so there is conservation of mass.
In order to have mass created or lost, a subatomic change must occur; such as atomic fission, fusion or decay.
It is dissolved into the surrounding air which cannot be detected by the scale. Google the law of conservation of mass to learn more.
No. Mass and Energy are always conserved in chemical reactions.
Yes. By Einstein's equation any time energy is gained or lost mass must do the opposite. The change is so small it is undetectable.
Calculating the mass of reactants and products in a chemical reaction is a sufficient demonstration.
Mass can not be changed
False
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 mass states that in a close container, when a chemical reaction occurs, no mass will be lost.
Calculating the mass of reactants and products in a chemical reaction is a sufficient demonstration.
Mass can not be changed
In a chemical reaction the mass of reactants is equal to the mass of products; burning is a chemical reaction.
the mass increases during a chemical reaction. because if heated or cooled then it would put on more mass for the atom.
False
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 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.
The law of conservation of mass states that in a close container, when a chemical reaction occurs, no mass will be lost.
A catalyst undergoes no chemical change during a chemical reaction.
The law of conservation of mass states that in a chemical reaction the mass of the reactants must equal the mass of the product.
Atoms cannot be added or lost in a chemical reaction.
Elements cannot be lost/gained: this is the law of mass conservation.
