I just know my daughter was our dependent the year she graduated from college because she lived with us until December, but she will not be this year (2012 taxes) since she has her own place. She is still on our health insurance until she's 26; however.
Answers. The law of conservation of matter states that in any given system that is closed to the transfer of matter, the amount of matter in the system stays constant. The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.
Matter is anything that takes up space and has mass. Matter is composed of atoms and molecules and is always changing its form by either physical or chemical changes. The Law of Conservation of Mass states that mass is neither created nor destroyed during any physical or chemical changes.
