In this [[Chemical Reaction|reaction]] you can see that '''mass is conserved''' because there are 4 [[Hydrogen]] [[atom]]s, 4 [[Oxygen]] [[atom]]s and 1 [[Carbon]] [[atom]] in the [[reactant]]s and all the same [[atom]]s are found in the [[product]]s.

Key Stage 3

Meaning

Conservation of Mass is a law of the universe that states that mass cannot be created or destroyed, it can only be moved from one place to another.

About Conservation of Mass

In a chemical reaction conservation of mass means that the same atoms with made up the reactants must make up the products. So the atoms are not created or destroyed in a chemical reaction, they are just rearranged.

Conservation of mass tells us that if there are 4 Hydrogen atoms and 2 Oxygen atoms at the start of this reaction then there will be the end of the reaction 4 Hydrogen atoms and 2 Oxygen atoms at the end of the reaction.

In this reaction you can see that mass is conserved because there are 4 Hydrogen atoms, 4 Oxygen atoms and 1 Carbon atom in the reactants and all the same atoms are found in the products.
