In chemistry, the term "yield" refers to the amount of a product or products a chemical reaction produces or "yields." There are two types of yields: theoretical yields and actual yields. As you determine a reaction's "actual" yield based on the amount of product you're able to "isolat...
Calculation of Theoretical Yield In chemistry terms we refer to yield as the quantity of product that can be produced from a reaction. Theoretical yield is the maximum amount of product that could be formed if conditions were perfect. Theoretical yield is based on the stoichiometry of th...

- 《Physics & Chemistry of Glasses》 被引量: 12发表: 1995年 The Effect of Mechanical Deformation on the Glass Transition Temperature of Polyurea The glass transition temperature (Tg)of a polyurea (Versathane P1000) is shown to be a function of mechanical strain and strain rate. For low ...
For chemistry and other sciences, it is customary to keep a negative value, should one occur. Whether error is positive or negative is important. For example, you would not expect to have a positive percent error comparing actual totheoretical yield in a chemical reaction. If a positive value...
Both types of chemical formulas yield useful information. The empirical formula tells us the ratio between atoms of the elements, which can indicate the type of molecule (a carbohydrate, in the example). The molecular formula lists the numbers of each type of element and can be used in writin...
Enthalpy is the thermodynamic function that describes heat flow. The calculation of the heat that is gained or lost can be determined by using the formula q = nCΔT. A negative result indicates that heat is lost when the reaction takes place, and a posit
Depending on the values of the kinetic parameters it is found that either a changing catalyst composition profile or a two-stage reactor containing the pure catalyst components gives an optimal yield. For some cases however, it appears that a constant catalyst composition profile gives yields close...
