Chemical Reactions What is a Chemical Reaction? Types of Chemical Reactions Redox Reactions Nonredox Reactions Classifying Reactions What is a Chemical Reaction? A chemical reaction is a process in which the identity of at least one substance changes. A chemical equation represents the total chemical change that occurs in a chemical reaction using symbols and chemical formulas for the substances involved. Reactants are the substances that are changed and products are the substances that are

that sample of matter is in a fixed state. There are two different types of properties: physical properties and chemical properties. A change is something that alters the properties of a substance. There are two types of changes: chemical changes and physical changes. A physical property is a property that can be observed without changing the makeup (or composition) of a substance. Some examples of a physical properties are texture‚ color‚ smell‚ and density. These are properties that can be measured

detail to recall is the difference between Kinesiology and its sub-division‚ Physical Activity. Since Kinesiology involves movement‚ most people misapprehend Kinesiology to be the study of physical activity. However‚ all physical activity is movement‚ but not to all movement is physical activity (Hoffman 2013). This paper is going to relate the significance of a physical activity I did in my life as well as the physical activity

Chemical Formula Principles Chemical Formula is a system of chemical notation that was invented in 181 by John Jakob Berzelius. The system is based on the law of definite proportions”‚ states that all samples of a given chemical compound have the same elemental composition. It is also a way of expressing information about the proportions of atoms that constitute a particular chemical compound‚ using a single line of chemical element symbols‚ numbers‚ and sometimes also other symbols‚ such as

A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole-dipole interactions‚ the London dispersion force and hydrogen bonding

CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant‚ a

matter using physical and chemical properties. Physical properties are characteristics of a substance. Two types of physical properties are quantitative and qualitative. Quantitative is a property that has an amount or can be measured such as hardness‚ solubility‚ and viscosity. Qualitative is a physical description of matter such as color‚ clarity‚ and state. Chemical properties are characteristics of a substance which allows it to behave in a specific manner. A few types of chemical properties are
