This is because they will repel each other to get as far away as possible from each other.]]> 2018-03-15 21:12:34 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242603988 Why are non-polar molecules more volatile (evaporate easily) than polar molecules https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604122 Because non polar molecules have weak intermolecular forced so the bonds can be broken easily.]]> 2018-03-15 21:13:10 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604122 Why are some molecules gases at room temperature? https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604187 Some molecules gases are at room temperature because they have weak intermolecular forces and are therefore able to evaporate at low temperatures.]]> 2018-03-15 21:13:28 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604187 Polar Molecules Dissolving in Polar Solvents dibleycq https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604218 The intermolecular forces are similar therefore they can break away from each other an form new intermolecular forces with the other solvent molecules.]]> 2018-03-15 21:13:36 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604218 Why don’t non polar molecules dissolve in polar solvents? https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604362 This is because the attraction forces between the non polar and polar molecules is not strong enough to make the molecules move a part, allowing them to mix together.]]> 2018-03-15 21:14:11 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604362 How do molecules with polar bonds become non-potable overall https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604499 If the molecule is symmetrical, the polar dipoles will then cancel out. ]]> 2018-03-15 21:14:30 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604499 what is a covalent bond? dibleycq https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604570 A covalent bond is a very strong bond formed when non metal atoms share a pair of electrons.]]> 2018-03-15 21:14:33 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604570 What determines if a covalent bond is polar or non polar https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604843 The different electronegativities the atoms that are covalently bonded together determines whether a bond is polar or not. A more electronegative atom will attract the bonding electrons towards it marking it slightly negative. The less electronegative atom will become slightly positive. This creates a polar bond. In a non polar covalent bond the bonding electrons are shared evenly]]> 2018-03-15 21:15:34 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242604843 Why are non-polar molecules more volatile (evaporate easily) than polar molecules? dibleycq https://padlet.com/dibleycq/7pq1fahyef2e/wish/242605078 because non polar molecules have weaker intermolecular forces than the intermolecular forces between polar molecules. This means that the intermolecular forces between non polar molecules can be broken easily allowing the molecules to turn into a gas.]]> 2018-03-15 21:16:35 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242605078 How do molecules with polar bonds become non-potable overall? https://padlet.com/dibleycq/7pq1fahyef2e/wish/242605195 Symmetrical molecules will cancel out the polar dipoles, then making the molecule non-polar]]> 2018-03-15 21:17:05 UTC https://padlet.com/dibleycq/7pq1fahyef2e/wish/242605195
