Chemists recognize many different elements, such as gold, or oxygen, or carbon, or iron. suppose you got some iron, and started splitting it into smaller pieces. the smallest piece that would still be called 'iron' would be:

12. complete each of the following word equations for synthesis reactions. a. sodium + oxygen -> b. magnesium + fluorine -> 13. complete and balance the equations for the decomposition reactions. a. hgo -> [with the triangle heat symbol above the arrow] b. h2o(l) -> [with "electricity" written above the arrow]
