Guida verificata passo dopo passo1
Understand the Law of Conservation of Mass, which states that mass cannot be created or destroyed in a chemical reaction.
Recognize that during a chemical reaction, atoms are rearranged but the total number of atoms of each element remains the same.
Note that while the number of atoms of each element is conserved, the volume of substances can change due to changes in state or gas expansion.
Realize that energy can be absorbed or released during a reaction, so it is not necessarily conserved in the same form.
Conclude that the quantity always conserved according to the Law of Conservation of Mass is the total mass of the system.
