Answer:The Law of Conservation of Mass states that mass is conserved in physical and chemical changes. Students explore this concept by taking initial masses, making predictions, and finding final masses of physical and chemical changes. Students observe water changing from ice to a liquid, a piece of cardboard being cut up, salt dissolving in water, Alka-Seltzer reacting in water, and water's physical property of cohesiveness being disrupted by soap.

What your cells have to help overcome a problem of high activation energy are called enzymes. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
Enzymes make things easier for your cells to work properly and help chemical reactions occur. There are hundreds of different kinds of enzymes in your cells, which all participate in different types of reactions. Enzymes can break molecules apart, build or add molecules, and even rearrange them.
In lowering the activation energy of a reaction, enzymes decrease the barrier to starting a reaction. It's important to note, however, that the change in energy remains the same between the start and end of a chemical reaction.
