4. Conservation of Mass is one of the key concepts to this unit. How do you think that is demonstrated in this reaction?

There is no reaction available for us to see.

Explanation:

However, the law of conservation of mass states that the number of atoms in the reactants side must equal the amount of atoms on the product side in a chemical equation. This is because mass cannot be created or destroyed. As a result, we must balance chemical equations to have the same number of atoms of each element on both the reactant and products sides. Additionally, with chemical reactions, all elements within the reaction must remain in the reaction. There cannot be new elements formed or lost in chemical reactions. Hope this helped!
