M 2 is the molar mass of gas 2. Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight. Thus, if the molecular weight of one gas is four times that of another, it would diffuse through a porous plug or escape through a small pinhole in a vessel at half the rate ...
When there is only one variable, polynomial equations have the form P(x) = 0, where P is a polynomial, and linear equations have the form ax + b = 0, where a and b are parameters. To solve equations from either family, one uses algorithmic or geometric techniques that originate from linear algebra or mathematical analysis.
However, if one searches for real solutions, there are two solutions, √ 2 and – √ 2; in other words, the solution set is {√ 2, − √ 2}. When an equation contains several unknowns, and when one has several equations with more unknowns than equations, the solution set is often infinite. In this case, the solutions cannot be listed.
Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the ...
The autism rate is at a level that nobody ever believed possible. When asked if the discussion could result in his administration getting rid of some vaccinations, Trump said: "It could if I think ...
This equation does not contain the temperature and so is not what became known as Charles's Law. Gay-Lussac's value for k (1 ⁄ 2.6666), was identical to Dalton's earlier value for vapours and remarkably close to the present-day value of 1 ⁄ 2.7315. Gay-Lussac gave credit for this equation to unpublished statements by his fellow Republican ...
It depicts real-life hedge fund manager Michael Burry (played by Christian Bale), one of the first people who recognized that many U.S. homeowners got their houses through subprime loans, creating ...
