Laws of Motion describe how objects move under the influence of different types of forces. These forces can be due to any physical phenomenon, but… Read More
The distinct forms that different phases of matter take on is called the state of matter. The most common state matter that is easily observable… Read More
Schrödinger used the electron’s wave-particle duality to design and solve a difficult mathematical equation that precisely represented the behaviour of the electron in a hydrogen… Read More
Neils Bohr, a scientist, expanded on Rutherford’s model of the atom through his experiments. The dual nature of electromagnetic radiation was an important element in… Read More
Jeremias Richter, a German chemist, was the first to create or discover the word Stoichiometry. The quantitative analysis of the reactants and products involved in… Read More
The chemical element hydrogen has the symbol H and the atomic number 1. The lightest element is hydrogen. Under normal circumstances, hydrogen is a gas… Read More
When the conditions are normal, all gases have similar behaviour. However, even slight changes in physical conditions such as pressure, temperature, or volume cause a… Read More
Thermodynamics is a branch of science in which the relation between work, heat, temperature, and energy is studied. Every day we encounter events that include… Read More
Characteristics of chemical systems are observable when they represent the bulk properties of matter. For example, an individual molecule does not boil, while a bulk… Read More
Organic chemistry is a discipline of chemistry concerned with the structure, characteristics, and interactions of organic molecules containing carbon in covalent bonds. Their structural formula… Read More
The Bohr model of the hydrogen atom was the first atomic model to successfully explain the atomic hydrogen radiation spectra. Niels Bohr proposed the atomic… Read More
Energy, like matter, is always conserved, which means that it cannot be created or destroyed, but it can be converted from one form to another.… Read More
The oxidation states of the reactants change in redox reactions, which are oxidation-reduction chemical reactions. The term redox refers to the reduction-oxidation process. All redox… Read More
Thermodynamics is concerned with the ideas of heat and temperature, as well as the exchange of heat and other forms of energy. The branch of… Read More
Any group of chemical compounds in which hydrogen is joined with another element is called a hydride. On the basis of the type of chemical… Read More
