Before You Begin: You may either copy and paste this document into a word processing program of your choice or print this page.Research the answers to the following questions on the internet and write your answers in your own words. For each answer include the address of the web site (or title and author of a book or article) that you used to help you answer the question.Before You Begin: You may either copy and paste this document into a word processing program of your choice or print this page.Part I: LabInsert completed data tables for each part of the lab. Be sure that the data tables are organized and include units when necessary.Part II: ConclusionAnswer the following questions in your own words using complete sentences.03.06 Covalent Bonding and Lewis Structures: Virtual Lab Text VersionSafety Information:Wash hands before and after handling chemicals. Wear goggles over your eyes whenever working with chemicals.Part I: Melting PointExamine the melting point of the following unidentified compounds by placing small amounts of the compound into a laboratory oven. If the compound does not melt by 300 C record the melting point as higher than 300 C. Record your findings in a data table.Results:Part II: ConductivityExamine the solid liquid and aqueous (dissolved in water) state of each compound to see if they are able to conduct an electrical current. If the substance is able to conduct electricity you will see the light bulb glow when both electrodes are connected to the substance. Record the results and observations in a data table.Results:03.06B Molecular Models: Lab and RubricBefore You Begin: You may either copy and paste this document into a word processing program of your choice or print this page.In this assignment you will draw models of four molecules based on their Lewis structures and answer 5 questions about each molecule you draw.Material IdeasIntroductionChemists often use three-dimensional models to help represent the geometry or shape of molecules. You can purchase a molecular modeling kit at university stores or on the Internet but in this activity you can make your own kit using the items listed above. In this assignment you have several different options to depict or show the geometry of your molecule. One of the options was shown in the lesson.ProcedureH2O NH3 CH4 CO2 a. For each molecule represent each element with a spherical (ball shaped) object. b. Each single bond should be represented with a straight object two straight objects should be used between two atoms to represent a double bond and three straight objects should be used between two atoms represent a triple bond. c. Remember that the lone pairs on the central atom take up space and play a role in determining the shape of the molecule. Represent each lone pair (nonbonded pairs of valence electrons) on the central atom with a nonbonded object. The bonds and lone pairs on the central atom should be spread apart as much as possible. See example in lesson as a reference.ConclusionFor each of your molecular models include a Lewis structure drawing or picture of your model (1 point for each molecular drawing). On your drawing or picture include the following information:
