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! Any redox reaction is made up of

allowing the citizens of a country to shape their government by electing officials to serve on their behalf. With any good system however‚ there are bound to be detractors. Plato is one of the most well-known detractors of the democratic system. In Book VI of the Republic‚ Plato compares democracy to an ill-governed ship. In this parable Plato lays out the deficiencies in the democratic system‚ and I agree with many of his points; however‚

Investigating the Effect of Temperature on the Permeability of Membranes The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents‚ for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to enter and leave the cell through facilitated diffusion the temperature must

Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen

Chemical Reaction: Cold Packs CHM110 Chemical Reaction: Cold Packs Introduction Chemical reactions happen every day in a variety of ways. We will explore the science behind cold packs and the chemical reactions that happen at the molecular level. Furthermore‚ we will examine and explain what chemical bonds are formed‚ broken‚ or both. The product is a simple construct of two bags: one containing water (solvent) and the other a chemical compound called ammonium nitrate (NH4NO3). In order to activate
