ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more

‘Newly industrialised countries have been‚ and continue to be‚ the driving force of globalization’ (40 marker) Globalisation is the process by which the world is becoming increasingly interconnected as a result of massively increased trade and cultural exchange. Globalisation has increased the production of goods and services‚ and allowed companies to become trans-national (TNC’s). Many TNC’s have headquarters located in more economically developed countries (MEDC’s)‚ with manufacturing plants in

Eric McKenzie Geophysical Science Honors February 14th‚ 2014 ACID RAIN 1. Acid rain is rainfall created by pollution in the atmosphere. When the rainfall occurs‚ it almost always causes harm to the environment. 2. Acid rain is caused by the release of certain compounds into the air‚ including sulfur dioxide and nitrogen oxides. These compounds mix and react with chemicals such as oxygen and water and form acid rain. 3. Acid rain can harm the environment by acidifying lakes and streams‚ which greatly

History can be viewed as a sequential series of indisputable events‚ whereas memory is of such events that are highly subjective‚ and affect the way in which they are perceived.We are shown this in the text ’The Fiftieth Gate’ which is a documented account written by Mark Raphael Baker as a historian‚ a father and also as a son.
