Nov 5, 2022 · The concept of determinants has its origin in the solution of simultaneous linear equations. In physical chemistry, they are an important tool in quantum mechanics. Suppose you want to solve the following system of two equations with two unknowns (\(x\) and \(y\)): \[a_1x+b_1y=c_1 \nonumber\] \[a_2x+b_2y=c_2 \nonumber\]

1 day ago · The Antoine Equation is a powerful tool for calculating the vapor pressure of a substance at a given temperature, widely used in the fields of chemistry and engineering. This equation is particularly useful for designing distillation processes, studying phase equilibria, and performing thermodynamic calculations in a variety of applications.
1 day ago · Ozone ( / ˈoʊzoʊn /) (or trioxygen) is an inorganic molecule with the chemical formula O. 3. It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O. 2, breaking down in the lower atmosphere to O. 2 ( dioxygen ).
