"Collision theory is a model for explaining chemical reactions and reaction rates using the interactions of particles within the reactants. There are three important parts to collision theory, that re ...
"Colligative properties are the properties of a solution as a whole and depend on the concentration. The colligative properties include freezing point depression, boiling point elevation, vapor pressu ...

"Chemistry can be broadly defined as the study of matter and the changes that it undergoes. In Chemistry there are several different branches including organic chemistry, inorganic chemistry, physical ...
"Carbohydrates are macromolecules composed of carbon, hydrogen and oxygen. Biologists are interested in carbohydrates because they serve as energy storage and as structural frameworks within cells. Si ...
"Physical matter properties include color, odor, density, melting point, boiling point and hardness. Physical properties are divided into intensive and extensive properties. Intensive properties are u ...
"The definition of chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It appears as though the reaction has stopped but in fact the rates ...
"Charles Law states that the volume of a given mass of a gas is directly proportional to its Kevin temperature at constant pressure. In mathematical terms, the relationship between temperature an ...
