Atomic Structure, Chemical Bonding, Lewis Structure, and 3D Molecular Shape Objectives In this lab, you will apply valence bond theory to draw appropriate Lewis structures, use electronegativity differences to classify bonds as ionic, polar covalent, or nonpolar covalent, and apply valence shell electron pair repulsion theory (VSEPR) to predict molecular geometry. We will also use molecular kits to create ball and stick models of molecules of interest to you. Theory Atoms of certain speci...

A. Watch Boyle’s Law and answer questions pertaining to it: 1. In this demonstration, did the volume of the balloon increase or decrease when the vacuum was applied? 2. The volume of the balloon increased and expanded when the vacuum was pumping the air out of the jar to try and equalize the pressure and when the vacuum was released 3. What properties of gas are being demonstrated in this experiment? What kind of relationship do they have? The volume and pressure are inversely related ...
