Hydrogen peroxide is a liquid people mix with water and use to disinfect skin wounds. Under certain conditions, the hydrogen peroxide molecule will break down and form water and oxygen. Look at the diagram showing before and after the molecule breaks down. What evidence supports that mass is conserved during this chemical reaction? Choose two that apply.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
