Unformatted text preview: 6.1 Chemical Equations When a piece of magnesium is added to dilute hydrochloric acid, fizzing occurs and hydrogen gas is released from the mixture. The fizzing is evidence that a(n) (1)__________________ has occurred between magnesium and hydrochloric acid. The name given to either magnesium or hydrochloric acid in this case is (2)______________________ , and the hydrogen gas that is released is called a(n) (3)___________________ of the reaction. Some other indications that reactions have occurred might be change of color or (4)_________________ , or formation of a solid (5)____________________ . If a thermometer is placed into a mixture undergoing chemical reaction, you might observed that the temperature has gone up or down, indicating that (6)_________________ was being released or absorbed. The short hand form by which a reaction is represented is called a(n) (7) ______________________ . In using this method of representation, you must satisfy the (8)____________________ , a principle that states that matter is neither created nor destroyed. In order to the (8)____________________ , a principle that states that matter is neither created nor destroyed....
