To learn more about acids and bases, review the accompany lesson on How to Calculate the Ka or Kb of a Solution. This lesson covers the following objectives: Understanding acids and bases at a molecular level Using an equation to determine how well an acid or base dissociates ...
is the ka value of HNO2 my equation NO2 + H2O - - > HNO2 + OH^- therefore i need the Kb of NO2 so i do: Kw/Ka 1.0E-14/5.6E-4 = ans 1 square root of (ans1 * 0.22) = 1.98208...E-6 check if within 5% and find it is well below 5% so valid. ...

non-hypoxic condition [67,68]. The tumor-initiation frequency was calculated. The longest diameter and its widest vertical width of tumor were measured every 3 days with a dialcaliper, and tumor volume was calculated by the equation (V = length × width2 × 0.5). At the end...
Are you sick and tired of trying to navigate through the world of choosing the ‘right’ whey protein for your needs? Just like for you, protein supplementation is a critical part of my daily diet. And if it isn’t a part of yours, why the heck not?? There is more than enough rese...
DF (Dissipation Factor) is defined as the ratio of loss energy to stored energy and typically being calculated as percentage. 2-2. Quality factor (Q factor) is defined as the ratio of stored energy to loss energy. The equation can be described as 1/DF. Normally the loss characteristic of...
A MathCad based computer program was continuity equation, developed for one-dimensional flow modelling purposes, and this through resolution of continuity and Mannings roughness energy equations, while the Manning equation was used to describe flow resistance. The Mannings coefficient roughness coefficient ...
