Week 10 - Naming , Formula Writing, More Naming, and Balancing!

So what is the difference between sodium and the sodium ion?  Would you believe one electron?  However, one is highly reactive in water and must be stored under oil and the other is simply combined with a majority of nonmetals and then dissolves readily in water.  So the idea of naming things correctly is pretty important.  Whether its sulfur trioxide (SO3) vs sulfite (SO3 2-) again it is important to understand the naming of substances.  With naming also comes writing formulas correctly.  This includes writing formulas of acids, formulas of molecules, and formulas of salts.  Once we progressed from naming and writing formulas we moved to balancing equations.  So this week and next will be lots and lots of practice.  Exams are coming soon!  Study guides will be arriving soon.

Finally, we ended the week with identifying the five types of reactions.
