Writing ionic equations for redox reactions You can split the ionic equation into two parts‚ and look at it from the point of view of the magnesium and of the copper(II) ions separately. This shows clearly that the magnesium has lost two electrons‚ and the copper(II) ions have gained them. These two equations are described as "electron-half-equations" or "half-equations" or "ionic-half-equations" or "half-reactions" - lots of variations all meaning exactly the same thing!

Maxwell Ampere Equations R. M. Kiehn (in preparation - last update 10/31/97) Physics Department‚ University of Houston‚ Houston‚ Texas Abstract: The topological universality of the Maxwell Faraday and Maxwell Ampere equations is an artifact of C2 differential forms on a domain of dimension n * 4. Starting with a 1-form of (electromagnetic) Action‚ the Maxwell Faraday equations become a consequence of the Poincare lemma. Starting from an N-1 form density‚ the Maxwell Ampere equations become a consequence

Accounting Equation Paper NAME ACC/300 INSTRUCTOR DATE The basic accounting equation is: Assets = Liabilities + Stockholders’ Equity. When looking at the balance sheet one can assume that assets must balance out each transaction and balance the claims to the assets (Kimmel‚ 2010). A balance sheet provides Assets of the company first and foremost‚ then Liabilities and Stockholders’ Equity and last retained earnings. This shows the companies incoming money‚ outgoing payments‚ and the

Significance of the Value Equation for Global Marketers According to Keegan (2002)‚ the value equation can be considered as a guide to create perceived value for customers by any organization operating anywhere in the world. The value equation is known as V=B/P‚ where V is the value‚ B is benefits and P is price. The value can be increased in two ways‚ by increasing the numerator ‘benefits’ or by reducing the denominator ‘price’. Keegan (2002) elaborates that the benefits can be increased by
