Weekly 5
In class this week, we went over Unit 2.3. We saw the differences between salt at sugar dissolved in water at the particle level, talked about the differences between ionic and covalent bonds, went over nomenclature and nearly watched the teacher electrocute himself. Wednesday was a portfolio day.
I learned that though most metals are conductive and most nonmetals aren’t, salt water is conductive because the ionic bonds break while in water. I learned the rules of nomenclature though I still struggle with some of the ionic compounds that contain a metal. I learned that acid is typically mixed with water and how to name the various acids based on their chemical formula.
Nomenclature is a lot like logistics. There are certain simple rules to naming compounds that need to be followed just like there are certain simple rules that need to be followed in logistics. In nomenclature, for ionic compounds, you name the cation first and then the anion with “ide” at the end. For compounds containing polyatomic ions, the suffix typically has ide/ate already at the end. In logistics, for shipments that clear customs at the port, you need a load number or a container number. For shipments that clear inland, you use an IT#. There are some exceptions in nomenclature. NH4+ is not nitrogen tetraoxide. It is ammonium. C2H3O2 is called acetate. There are also exceptions to the rules in logistics. All cargo must clear customs before it is delivered to the customer. For free trade zone shipments, cargo will clear customs the moment it is delivered to the customer.
