  20. In a chemical reaction, how do the properties of the reactants and the products compare?

  21. The properties will change because the atoms of the products rearanged.

  22. What does the law of conservation of matter say? • What does it say about counting atoms?

  23. a)Matter can not be created nor destroyed in a chemical reaction. b) There must be the same # of atoms of eachelement on each side of the equation.

  24. Substances formed in a chemical reaction are called ______.

  25. The products

  26. b) If the equation is balanced, what does that mean? a) Is this equation balanced? Cu(SO4) + H2S H2(SO4) + CuS

  27. Yes, the equation has the same number of atoms of each element on each side of the equation.
