Section 3: Procedure In this experiment‚ I observed substances in their natural state‚ and recorded their apparent physical properties. I then tested the substances to determine how they react when their natural environments were altered. The pure substances were tested to see

Chemicals of Life • With the exception of water‚ virtually all chemicals of life are CARBON based • Molecules that contain Carbon are considered organic with some exceptions such as CO2 • Carbon has 4 valence electrons so it is oriented in a tetrahedron shape Sketch→ • Carbon can form up to 4 covalent bonds and can form long chains‚ rings‚ and branched chain molecules • Carbon acts as the backbone of biological molecules • Molecules that only contain carbon and hydrogen are known as hydrocarbons→

November 28‚ 2014 ! ! Physical and Chemical Properties! Purpose/Hypothesis:! • The purpose of this experiment is to investigate the chemical and physical properties of pure chemical substances. A property of a substance is some distinguishing characteristic. Some of the most common physical properties are color‚ odor‚ hardness‚ density‚ melting point‚ boiling point‚ and solubility in various solvents. For all of these properties‚ no chemical change takes place. Chemical properties describe the

Title: Observations of Chemical Changes Purpose: The purpose of this experiment is to predict and examine chemical changes/reactions among common chemicals found in consumer products at a macroscopic level. Procedure: The procedure of this experiment was to carefully mix different chemicals together using the chemical filled pipettes and the 96-well plate and determining what chemical reactions occurred. Data Table: Observations of Chemical Changes Experiment 1: Observations of Chemical Reactions

2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and to associate chemical properties with household products. Procedure: In this experiment I used a 96-well plate to hold each of the chemical reactions that occurred during this lab. Using a pipet‚ I added two drops of one chemical with two drops of another chemical and observed the effects of each reaction. Data Table 1: Experimental Data Well # | Chemicals | Observations | |
