Description du contenu de l'enseignement

UNIT I:General introduction to the study of chemistry.
Everything else is somehow related to chemistry, the scientific discipline which studies the properties, composition, and transformation of matter.
Basic chemistry course is intended to serve as a broad introduction to a variety of concepts in chemistry and is widely taught. At the university level, it is also sometimes used as a "weed out" course for disciplines, which are perceived to require a high level of intellectual rigor, or large course loads. It is also one of the few chemistry courses in most universities that does not explicitly explore a particular discipline such as organic chemistry or analytical chemistry. Though the list of subjects covered is typically broad, leading some to criticize both the class and the discipline as encouraging memorization, most general chemistry courses are firmly grounded in several fundamental physical rules for which the primary challenge understands when the rules are applicable.
There are many reasons to study chemistry. It is one pillar of the natural sciences necessary for detailed studies in the physical sciences or engineering. The principles of biology and psychology are rooted in the biochemistry of the animal world, in ways that are only now beginning to be understood. Modern medicine is firmly rooted in the chemical nature of the human body etc. It is impossible to imagine modern society and technology without knowledge of chemistry. We use chemical principles to understand a host of phenomena, from the role of salt in our diet to the working of a lithium ion battery.
Chemistry has the power to explain everything in this world, from the ordinary to the bizarre. Why does iron rust? What makes propane such an efficient, clean burning fuel? How can soot and diamond be so different in appearance, yet so similar chemically? Chemistry has the answer to these questions, and so many more. Understanding chemistry is the key to understanding the world, as we know it.
UNIT II:Matter and its classification. Physical and chemical properties of matter.
What is matter? Two principal ways of classifying matter. Classification of matter by its physical state: liquids, solids and gases. Classification of matter by its chemical constitution. Mixtures and pure substances. Elements and compounds. Homogeneous and heterogeneous mixtures. Physical and chemical properties of matter.

UNIT III:Measurement and significant figures. Handling numbers. Units and dimensional analysis.
Description of chemistry subject as a quantitative science. Nubmers and units. Metric system. The standard international (SI) system of units. SI base units. SI derived units.Quantities frequently required in problem solving. Uncertainties in scientific measurements. Precision, accuracy, error.Evaluating measurements. Error and percent error. Scientific notation. Significant figures. Guidelines for using significant figures. Handling significant figures in calculations. Problem solving in chemistry. Dimensional analysis or factor-label method.

UNIT IV: The concept of the mole and the Avogardo constant.
Avogadro’s number and the molar mass of an element. The mole concept. How big is a mole? Counting using mole. Mole and mass. Molar volume. Calculations involving mole, mass, molar mass, molar volume and Avogadro constant.

UNIT V : Introduction to aqueous solutions. Concentration.
Solution and its constituents: Solute and Solvent. Aqueous solutions. Water as a universal solvent. Types of solutions. Solution Concentration: Molarity, Molality, Molar Fraction, Percent, ppm/ppb. Preparing Aqueous Solutions by weighing chemical compound and dilution of a stock solution.

UNIT VI: Training exam and consultation after the exam.
This unit consists of 2 parts: a) Organization of a training exam with the same conditions as a real exam and maki ng students to feel the spirit and progress of an examination at UFAZ. Brief discussion in class after correction of copies by an instructor. b) Holding a real exam and organization of 1 lesson as a consultation of the real exam. Here students get correction of all exam questions and review over their mistakes during the exam.

UNIT VII: Naming compounds and writing formulas.
Naming and writing formulas of Inorganic Compounds: ionic compounds, molecular compounds, acid and bases, hydrates. Naming organic compounds: IUPAC nomenclature functional Groups

UNIT VIII: Data analysis.
Data and Information. Scientific Method. Representation of Data: types of graphs. Control Variable. Mean and Standard Deviation. Practical Example

UNIT IX: Stoichiometry. Empirical and molecular formulas.
Percent composition of compounds. Experimental determination of empirical formulas. Determining molecular formulas. Combustion Analysis. Amounts of reactants and products. Theoretical Yield, Actual Yield, Percent Yield. Limiting and Excess Reactant.
