Unit 2: Atoms, Molecules & Ions

2.5 Formulas & Nomenclature
 I can write ionic and covalent chemical formulas and use proper nomenclature for each
2.5a Microscale  Chemical Names and Formulas
Exploration Objective
 What determines how many ions are needed in a compound?
 How are the number of ions denoted?
 Is there a pattern in the formulas?
 Why are they arranged in that order?
2.5b Ionic, Molecular, Binary, Ternary...
Every chemical has a unique formula and a unique name. If you know one, you know the other. The left hand vodcast walks you through the basics of formulas and naming (some of which you may already know). The right vodcast adds basics about organic names/formulas and some practice going back and forth from formulas to names and names to formulas. You will need your flowcharts while you watch and work.
Quiz #4: Sections Review & 2.5
2.6 Equations
 I understand and can explain conservation of mass
 I understand and can explain the conservation of atoms through rearrangement in chemical equations, demonstrated through symbolism and particle diagrams
2.6a These Guys & Those Guys
Exploration Objective
 What does conservation of mass mean?
 Is matter really conserved in a chemical reaction? How do you know?
 Was there a predictable relationship?
 Would this apply to any substances or just these guys?
2.6b MINOH
Balancing equations are the next step. It is through equations we are able to calculate amounts of substances from other substance (where we are headed).
