Course Overview
Chemistry is a central natural science that bridges the gap between physics and biology. Understanding the key concepts of general chemistry is both necessary and beneficial for a broad spectrum of science, engineering and healthcare majors. However, without some hands-on laboratory experience, this understanding is likely to be incomplete, if not deficient, because chemistry is mostly an experimental (empirical) science. This course would provide the actual lab experience that is useful or even essential for a natural scientist, an engineer or a clinician/pharmacist. Beyond majors in chemistry the target student audience can pursue a career in medicine, biology, physics, forensic science, engineering, geology, ecology, and etc. Beyond helping to understand concepts of chemistry and improving problem solving skills, this course is likely to enhance students’ lab techniques. The course may even improve dexterity (which is essential for many occupation from cooking to surgery) of some students. All benefits that may be associated with serious and responsible learning of this course are too numerous to be listed here.
The course goes hand in hand with General Chemistry lecture course, which covers the following topics:
1. CHEMISTS AND CHEMISTRY.
2. ATOMS, MOLECULES AND IONS.
3. STOICHIOMETRY.
4. TYPES OF CHEMICAL REACTIONS AND SOLUTION STOICHIOMETRY.
5. GASES.
6. ENERGY, ENTHALPY, AND THERMOCHEMISTRY.
7. QUANTUM MECHANICS AND ATOMIC THEORY.
8. BONDING: GENERAL CONCEPTS.

    A reflux condenser was assembled using a 25-mL round-bottom flask, hot plate, and aluminum block. It was equipped with a drying tube filled with calcium chloride to control vapors. Approximately 2.5 mL of isopentyl alcohol was massed and placed in the round-bottom flask that contained a stir bar. Using the same graduated cylinder, about 3.5 mL of glacial acetic acid was added to the flask. A calibrated Pasteur pipet was used to add 0.5 mL of concentrated sulfuric acid to the flask and the flask was mixed immediately. The flask was connected to the apparatus and covered with aluminum foil to help retain heat. Using rubber tubing, water was circulated into the lower attachment and out the top attachment and the mixture was brought to a boil. After heating under reflux for 60-75 minutes, the flask was removed from the heating source and left to cool down to room temperature. The reaction mixture from the flask was transferred to a culture tube and 5-mL of water was added. Upon addition of water, careful shaking, and occasional venting, the phases separated and the lower aqueous layer was removed and discarded. Using the same procedure as explained above with water, 2.5 mL of aqueous sodium bicarbonate was added and the lower aqueous layer was again removed and discarded. The same procedure was repeated one last time with 2.5 mL of saturated aqueous sodium chloride and the lower aqueous layer was removed and discarded, leaving behind the crude ester. The crude ester was transferred to…

    We placed the zinc inside the beaker and slowly poured the hydrochloric acid into the beaker. As soon as the acid entered the beaker, there was a sizzling sound and bubbles started to form as we add more of the substance in. When the bubbles were forming, we could see a steam of gas coming out of the beaker. After 10 minutes, we noticed bits of zinc were floating on top of the hydrochloric acid and lining the beaker. I lifted the beaker and felt the bottom and it felt warm, which meant the reaction was still happening. After 20 minutes, we added water into the zinc and hydrochloric acid to stop the reaction and we observed a slight cloudy colour (still clear) forming as we slowly pour the water in the beaker.…

    course usually taken during the first college year. For some students, this course enables them to undertake, in their first year, second-year work in the chemistry sequence at their institution or to register in courses in other fields where general chemistry is a prerequisite. For other students, the AP Chemistry course fulfills the laboratory science requirement and frees time for other courses. AP Chemistry should meet the objectives of a good college general chemistry course. Students in such a course should attain a depth of understanding of fundamentals and a reasonable competence in dealing with chemical problems. The course should contribute to the development of the students’ abilities to think clearly and to express their ideas, orally and in writing, with clarity and logic.…

    Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy. Most people have chosen to write their essay about how chemistry has played an important role in everyday life. The simple fact is that chemistry plays an important role in every person’s daily activities from the moment we’re born. Chemistry is the branch of science that deals with the structure of organic and inorganic matter( any substance or organism which has a mass and occupies space), its properties and reactions; however chemistry is primarily the study of reactions that any given substance takes on when interacting with another substance. Chemistry is the main incentive for the life that we live today; it has provided modern society with facilities that make our day to day lives easier. chemistry has allowed us to understand the composition of the world. In short this branch of science has enabled us to lead a better quality of life.…
