Chemical Bonding and the Properties of Solids— Laboratory Kit
By: The Flinn Staff
Looking for patterns in the properties of different substances can help us understand how and why atoms join together to form compounds. What kinds of forces hold atoms together? How does the nature of the forces holding atoms together influence the properties of a material?
In this experiment, students study the physical properties of common solids and investigate the relationship between the type of bonding in a substance and its properties, volatility (odor), melting point, solubil- ity, conductivity, hardness and brittleness. Students identify the type of bonding in a solid by comparing its observed properties to the general properties of covalent-network, ionic, metallic and molecular solids.
Enough materials are included for 24 students working in pairs.
Lewis Structures and Molecular Geometry— Laboratory Kit
By: The Flinn Staff
Molecules have shape! The structure and shape of a molecule influ- ence its physical properties and affect its chemi¬cal behavior as. Lewis structures and VSEPR theory offer useful models for visualizing the structures of covalent compounds. Students practice drawing Lewis structures of molecules and use these structures to predict their molecu- lar geometry. Molecular models will be studied to visualize the shapes of molecules and to sketch their three-dimensional structures.
Complete for six student groups.

Mole Ratios—Laboratory Kit
By: The Flinn Staff
The reaction of copper wire with silver nitrate in aqueous solution provides a beautiful display of chemistry in action—delicate silver crys- tals begin to grow on the wire surface and the color of copper(II) ions gradually appears in solution. What relationships govern the relative quantities of reactants and products in this chemical reaction?
Students measure the mass of the silver produced, determine the mass of copper wire that reacted, and calculate the number of moles of each. After comparing the number of moles of reactants versus products, students determine the mole ratio and write the balanced chemical equation for the reaction.
Complete for 24 students working in pairs.
