Chem 1201 Exam 5 With 100% Correct And Verified Answers 2024

Chem 1201 Exam 5 With 100% Correct And Verified Answers 2024 kinetic molecular theory - Correct Answer-physical properties of a substance understood Are gasses highly compressible or low compressible? - Correct Answer-highly compressible If liquids are almost incompressible, can you assume the shape and or the volume of the container? - Correct Answer-you can assume the shape not the volume Are liquid or gas molecules closer held together? - Correct Answer-liquid molecules, but not so rigidly that the molecules can't slide past each other If solids are incompressible,do they have a definite shape and/or volume ? - Correct Answer-they have both a definite shape and volume What does converting a gas into a liquid or solid require the molecules to do? - Correct Answer-get closer to each other, cool or compress What does converting a solid into a liquid or gas require the molecules to do? - Correct Answer-move further apart heat or reduce pressure intermolecular forces - Correct Answer-forces holding solids and liquids together intrAmolecular forces - Correct Answer-a force that holds 2 atoms together by the forming of a covalent bond intERmolecular force - Correct Answer-a force of attraction between molecules Why are particles(molecules or atoms) sticky? - Correct Answer-due to intermolecular forces Are IMF weaker or stronger than covalent or ionic bonds? - Correct Answer-weaker When a substance melts or boils, what happens to the intermolecular bonds? - Correct Answer-the intermolecular forces are broken When a substance condenses, what happens to the intermolecular forces? - Correct Answer-the intermolecular forces are formed Ion-Dipole Forces - Correct Answer-interaction between an ion and a polar solvent, which requires a net dipole for the molecule Are the Ion- Dipole forces that strongest or weakest intermolecular force? - Correct Answer-strongest What does strength depend on? - Correct Answer-Dipole moment, ionic ionic charge, charge density. The larger the charge the smaller the ion the larger the ion-dipole attraction Dipole- Dipole Forces - Correct Answer-exist between neutral polar molecules with NO hydrogen bonds (3rd strongest) Are Dipole-Dipole Forces stronger or weaker than Ion Dipole force? - Correct Answer-weaker Hydrogen Bonding - Correct Answer-special case of dipole-dipole forces the boiling points of compounds with H-F,H-O,&H-N Are the intermolecular forces for hydrogen bonds abnormally stronger or weaker? - Correct Answer-stronger London Dispersion Forces - Correct Answer-The weakest type of intermolecular forces. Non polar bonds are involved. Associated with ALL IMFs Which type of IMF's operates between all molecules? - Correct Answer-London Dispersion Forces Which type of IMF's operates between polar molecules? - Correct Answer-dipole-dipole, dispersion Which type of IMF's operates between the hydrogen atom of a polar bond & nearby electronegative atom? - Correct Answer-dipole-dipole and in certain cases (O,N,F) hydrogen bonding What kind of attractive force must be overcome to boil water? - Correct Answer-Hydrogen bonding What kind of attractive force must be overcome to melt KCl (solid)? - Correct Answer-ionic bonds
