Physical and Chemical Properties Chem 107 6-4-2013 A pure substance or chemical substance is a material that is homogeneous. It has consistent properties throughout the sample.” Pure substances can be described by both physical and chemical properties”. Physical properties can include‚ color‚ odor‚ melting point‚ boiling point‚ and solubility in various solvents‚ etc. The observation of these physical properties does not involve any chemical change in the substance‚ it is still the same

Abstract: The objective of Experiment 1 was to observe some chemical changes. While observing the chemical changes in elements I also experimented with household cleaners to see how much chemical properties relate to our daily lives. Chemical changes occur all around me and I go without noticing them all the time without a second thought. This experiment opens my eyes to different chemical reactions occurring around me. This experiment also shows the importance of dilution. If I did not dilute something

Extracurricular Activities on Academic Performance at NSU Introduction Music‚ volunteer work‚ community service‚ sports‚ debating‚ etc—all of these have an influence on how university students perform academically. The way students choose to spend their free time can affect their academic performance; it is not simply traditional in-class instruction that impacts academic achievement. “A study by the U. S. Department of Education revealed that students who participate in co-curricular activities are three

Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate
