The Effect of Chemicals on Fire In this lab we got to see the effect of chemicals on fire. We got to. See the flames change to different colors. The size of the colorful flame depended on how the Bunsen burner was turned on. I was sick when we were supposed to have the lab read‚ but I got it read the next day before class. During the lab I made sure to have the correct attired on: my goggles and apron. Ow ill go ahead and tell you five good safety precaution tips. One‚ never leave a lit

ic level‚ influencing inflation rates and fluctuations “in aggregate supply and demand.” (Healey 1999) The formation of the EU‚ highlighted the importance of a central economic policy. The introduction of a single currency would allow Europe to partially achieve this by encouraging interstate trade and ridding of any trade tariffs that may still exist‚ this was achieved through the 1986 Single European Act‚ “the EU set about dismantling the remaining non‐tariff barriers to the free movement of goods

Chemical Reactions Lab Objectives: 1. To examine a variety of reactions including precipitation‚ acid-base‚ gas forming‚ and oxidation-reduction reactions. 2. To identify the products formed in these reactions and summarize the chemical changes in terms of balanced chemical equations and net ionic equations. 3. To identify the species being oxidized and reduced in oxidation-reduction reactions and determine which species is the oxidizing agent and the reducing agent. Chemical equations represent

Chemical changes are irreversible because substances mix and cause a reaction which creates a new substance. Chemical changes can be caused when a substance is combined with a heat‚ water or another substance. Heat can cause a chemical reaction called caramelisation which is when sugar is heated at a high temperature causing it to break down. This gives the sugar a nutty

Classes of Chemical Reactions Whenever a reaction takes place‚ energy is changed as well when the substances react chemically. Scientists have taken these changes in energy and generalized them. Scientists can take these generalizations and discover more about the nature and tendencies of matter. In this lab‚ the purpose was to perform seven reactions‚ write down their equations‚ and identify the type of reaction. In this lab report‚ several methods of displaying this information will be applied

The potato’s introduction into Europe proves to be one of the most significant examples of a foreign food crop being able to extensively affect the lives of a an Old World Population. Before the assimilation of the potato crop into the majority of Europe’s agricultural landscape‚ peasant populations constantly faced famines while current food sources provided little nutritional value and were not efficient sources of energy. As Europe adopted the brown tuber‚ people were provided with a far more
