A chemical bond is a force holding two or more atoms or ions to form large varieties of compounds. There are many types of bonds, for example, the covalent bond.
Over the course of history, many models of the atom have been proposed. Each model built on top of the previously held model. Do you the famous ones?
In 1808, an English school teacher, John Dalton proposed that “An atom is the smallest indivisible particle of matter, which can take part in chemical reactions.”
What is precision and what is accuracy? What’s the difference?
Enthalpy, H, is another state function used to describe the amount of heat, q, at constant pressure.
During a physical or chemical change, the change in internal energy is accompanied by the heat absorbed or liberated by the system, q, and/or the work done by or on the system.
Thermodynamics is an area of physical chemistry that studies energy and its transformations. One particular sub-area of thermodynamics concerns with the transformation of energy in a chemical reaction and that is, thermochemistry.
