Boiling water Lab

During our lab we heated ice and sugar together at 350 degrees Celsius the strength of water intermolecular forces increases. When heated waters intermolecular forces, boiling points, and melting points all are relatively similar to each other.
When adding salt to an icy sidewalk the ice melts quickly although if you added sugar to it, the ice would evaporate more slowly because it changes the composition and loosens the intermolecular forces.

Physical Properties

During this section we learned about the physical properties of Macromolecules, Metalloids, Ionic Compounds, Non-metals, Covalent Compounds, Network Solids, and Metallic Compounds. Each of these things have similarities and differences. Macromolecules, Metalloids, Ionic Compounds, Network Solids, and Metallic Compounds all have HIGH melting and boiling points; while Non-metals and Covalent Compounds have LOW melting and boiling points. We also tested all of these things for Electrical Conductivity, Malleability, Ductility, and Luster. It was found that some substances have these qualities while others do not.

Molecules

During this section of class we learned about the Lewis structure and how to form ionic and covalent bonds. The Lewis structure helps you see how to combine different elements to form bonds so that the outer most shell is full of valence electrons. We learned that when making a covalent bond which is two nonmetals you must use the prefixes when naming the elements. While Covalent bonds are made of only nonmetals, Ionic bonds must have a metal in them.
