chemical property- A property or characteristic of a substance that isobserved during a reaction in which the chemical composition oridentity of the substance is changed physical property- Any property used to characterize matter and energy and their interactions homogeneous- of the same kind heterogeneous- diverse in content suspension- temporary prevention solution- being desolved density- the degree of compactness of a substance filtrate-liquid that has passed through a filter atom- basic unit of a chemical element element- a pure chemical substance consisting of one type of atom distinguished by its atomic number, which is the number of protons in its nucleus. molecule- group of atoms bonded together compound- a mixture of elements physical change- a physical difference chemical change- a chemistry difference

Analysis We started with a 140 mL, heterogeneous suspension. There were small particles in the solution that settled at the bottom and it smelt of oil. It was a brownish color with about 15 mL of oil on top, and it smelt of garlic, and vinegar. Next, we did the oil-water separation and were left with about 125 mL of water. The physical change of the water was that it became a lot cleaner and there were less black particles floating around. After, we did a sand filtration and were left with 123 mL of water. The solution looks foggier and there was no oil or black pieces suspended in the water. OUr next procedure was the charcoal absorption, the water was black and had the same odor. We then, poured it into a funnel with filter paper over a beaker and watched it slowly become cleaner water. We don't believe there were any chemical properties we only observed physical properties
