5 - $200 When a solid is dissolved in water, we refer to the phase as “aqueous” or (aq). What role does water play in the reaction. Water does not participate in the reaction. It just the medium in which the reaction takes place.

5 - $300 The law of conservation of mass states that atoms cannot be created or destroyed, but rather are ___________ as a result of the chemical reaction. Rearranged

5 - $400 The law of conservation of mass states that the mass of the __________ and the mass of the ________ must be __________. Reactants, products, equal

5 - $500 The four indications of a chemical reaction are… 1. heat and light 2. gas produced 3. precipitate forms 4. color change

Final Jeopardy Why can we change the coefficients of a chemical equation and not the subscripts? Subscripts tell us how many of each atom make up the molecule. They tell us the IDENTITY of the molecule, which we cannot change. Coefficients tell us HOW MANY of each molecule are needed for an equation to be balanced and obey the law of conservation of mass.
