WebWhat is equilibrium constant (K eq)?. The equilibrium constant may be defined as the ratio between the product of the molar concentrations of the products to that of the product of the molar concentrations of the reactants with each concentration term raised to a power equal to the stoichiometric coefficient in the balanced chemical reaction. WebFormula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical …
WebGravitational force F_g F g is always attractive, and it depends only on the masses involved and the distance between them. Every object in the universe attracts every other object with a force along a line joining them. The equation for Newton’s law of gravitation is: F_g = \dfrac {G m_1 m_2} {r^2} F g = r2Gm1m2. WebJan 6, 2024 · Equivalent weight isn't really a weight-- it's a mass. Mass is the amount of matter in something, while weight is the gravitational pull on a mass. Since we're only dealing with different chemical ...

In chemistry, equivalent weight (also known as gram equivalent ) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance. The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or … See more The first equivalent weights were published for acids and bases by Carl Friedrich Wenzel in 1777. A larger set of tables was prepared, possibly independently, by Jeremias Benjamin Richter, … See more When choosing primary standards in analytical chemistry, compounds with higher equivalent weights are generally more desirable because weighing errors are reduced. An example is the volumetric standardisation of a solution of sodium hydroxide which … See more In polymer chemistry, the equivalent weight of a reactive polymer is the mass of polymer which has one equivalent of reactivity (often, the mass of polymer which corresponds to one mole of reactive side-chain groups). It is widely used to indicate the … See more The use of equivalent weights in general chemistry has largely been superseded by the use of molar masses. Equivalent weights may be … See more The term “equivalent weight” had a distinct sense in gravimetric analysis: it was the mass of precipitate which corresponds to one gram of analyte (the species of interest).
