Mass can not be changed
Matter is not lost in a chemical reaction, as the total mass of the reactants is always equal to the total mass of the products. This principle is known as the law of conservation of mass.
This is a balanced chemical reaction.
NO
They are lost.
False
Calculating the mass of reactants and products in a chemical reaction is a sufficient demonstration.
atoms are not lost or gained in a chemical reaction
Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.
This is a balanced chemical reaction.
NO
no
They are lost.
In a chemical reaction the mass of reactants is equal to the mass of products; burning is a chemical reaction.

Reduction Is Gain of electrons
False
Atoms cannot be added or lost in a chemical reaction.
