Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. 0000068664 00000 n They are INTERmolecular forces, meaning you need to have at least two molecules for the force to be between them. Apple juice had the higher boiling point at 160, compared to vinegar at 188; therefore, it has stronger intermolecular forces between its molecules. You will figure out how to tell the different intermolecular forces apart, identify the substances where they are likely to occur, estimate their relative strength, and relate them to the bulk properties of matter. Intermolecular Forces Lab Worksheet . Understand the use of graphical methods to extract thermodynamic information from experimental pressure and temperature data. At the end of this simulation, you will be able to: Describe how dispersion forces, dipolar forces, and hydrogen bonding between molecules arise, Identify molecular motifs and features that may contribute to intermolecular force induction, Predict the types of intermolecular forces present between different molecules. @ [. %P|H@ dgf6.*`"@3A-Ra]IS 9P*MMcv:'ULs !e;;WF?#j=Ll@ -$He \3qft;~DnKn8p'Oy%5?
