About chemistry school college courses
:: During the last few years, the board students in the chemistry of the different regions in the world have been trying to modernize. Hence the syllabus of chemistry changed. Therefore, this change results in a shortage of suitable texts for school college students. The Author seeks this change and trying to fulfill this gap.
:: This Page designed to incorporate the latest recommendation in the field of chemistry.
:: All the posts, pages, and application of principles are published in the form of solved problems and numerical for the chemistry tests.
:: Posts and pages contained in this domain proper headings to understand the text in a more systematic manner.
:: All posts and pages updated regularly and the labels give for this updating.
:: The author wishes to thank all those who helped in the presentation of the posts and pages. Since drawbacks and better methods of presentation are always there. Suggestions for improvement and criticism will be gratefully received and acknowledged. Therefore, any improvement please contact online.
How to teach chemistry online?
In recent years teaching classes of chemistry in many schools, colleges, and universities are changes. The syllabus of education based on a theoretical and conceptual method and the application of the basic concepts. Therefore, we observed this change in chemistry classes and frightened undergraduate students whose performance in chemistry far from satisfactory.
This poor performance partly because of the non-availability of the comprehensive notes. This stresses the logical deduction and the solution of numerical. Therefore, the students find themselves unduly study materials. We published some posts and pages which cover the theory as well as the application of this study materials. Online learning school college chemistry courses primarily intended for our readers to find chemistry topics more easily.
About States of Matter in Chemistry
Crystalline or amorphous solids are characterized by their high density and low compressibility compared with those of the gas phase. Therefore this part provides different topics related to solid and gaseous-state chemistry like cubic crystal, properties of gases, surface tension, diffusion, ideal gas law, Van der Waals gas, etc. In order to determine experimentally the properties of substances, we deal with the aggregates of molecules as they occur in the environment. Therefore, various kinds of substances that made up the matter divided into three main categories, namely gases, solids, and liquids. These states of matter are interchangeable. For example, below the critical temperature, the gas is liquified to form solid or the specific heat solid converted into the liquid state.
Learning About Chemical Equilibrium and Kinetics
In this part, we can deal with the equilibrium of a chemical reaction such as homogenous and heterogeneous. Mass action law, Vant Hoff equation, and Le Chatelier principle constructed the equilibrium laws on the basis of thermodynamics energy conservation, free energy, internal energy, entropy, enthalpy, etc. To know the speed of a chemical reaction we need to know about how much time needed to complete the chemical reaction. Therefore, chemical kinetics and catalyst is an essential part of chemistry to determine the speed of zero-order, first-order, or second-order chemical reaction.
About Learning Polarity of Chemical Bonds
A polar molecule is one in which there will be the separation of the center of gravity of the positive charge and negative charges. Therefore, polarity developed a positive and negative pole in the chemical bond. In an electric field, the polar molecule tends to align themselves with the positive ends face negative pole of the electric field but the negative ends face the positive pole. Hence the electric polarization of molecules expressed by the dipole moment.
