(see figures below) has a lincarimolecular geometry. exhibits a bond angle of 120". contains a double bond. (see figures below) occupy a larger region of space. is the bond angle of water. 21. Geometry Electronegativity plays a role on the overall polarity of a molecule. 22. Jonic Covalent 23. 0: CO₂ bonds have the capability of being polar or non-polar, is non polar and is a gas at room temperature. contain molecules that move faster. 24, Gases Liquids 25. 760 mmHg 101.3 kPa is standard pressure. is determine via electronegativity. substances tend to have higher boiling points. substances have a tendency to evaporate quickly. is assigned to the atom with a greater electronegativity. employ hydrogen bonding. substances are miscible with non polar substances. is an electronegativity difference that results in a polar bond. 44 F7 DII F8 DD F9 J F10 3 FI
