Application/Connection: Ws: Great Combinations Exit: How many elements/compounds are in the equation: C 3 H 8 + 5O 2  3CO 2 + 4H 2 O? Practice: Name the elements in each of the compounds, then count the number of atoms in each EQ: How does the structure of matter explain its properties and the changes it under goes?
