Introduction: A chemical reaction is formed of reactants and products. Reactants react with each other to give one or more product. Sometimes we can visualize observations that are characteristic of the reaction. Like for example a release of a gas (bubbles are formed) or a change of color or also the formation of a precipitate. Materiel needed: Test tubes Rack of test tubes Plastic droppers Beakers Procedure: We prepare 7 beakers of 7 different solutions (that we mark from 1→ 7). We put

a reaction. Moreover‚ it also tells you how a particular mixture of chemicals will react. This is because chemical reactions always occur in the direction which will make the ratio of their products to reactants equal to the equilibrium constant. In chemistry‚ Le Chatelier’s principle‚ also called Chatelier’s principle or "The Equilibrium Law"‚ can be used to predict the effect of a change in conditions on a chemical equilibrium. The principle is named after Henry Louis Le Chatelier and sometimes

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

Example: H2O‚ CO2 2. How is electronegativity used in determining the ionic or covalent character of the bonding between two elements? A: A large difference in electronegativity between two atoms in a bond will result in ionic bonding. A small difference in electronegativity between two atoms will result in covalent bonding. Translation: Electronegativity difference between 0-0.3 = Non-polar covalent bond Electronegativity difference between 0.3-1.7 = Polar covalent bond Electronegativity

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants

Describe the difference between a mixture and a compound. A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components‚ a compound cannot. Below are some examples of the differences between each. Compounds •Compounds are pure substances. •They are made up of two or more elements

Tavaski Gordon December 17‚ 2013 HS 251 Unit 14 Paper Bio-Chemical Weapons The use of biological and chemical weapons has been practiced for many centuries. It started from the late 400s BC up to the twenty first century‚ and is still currently being practiced today. Ever since these weapons were introduced‚ they have been used by individuals‚ groups‚ or countries to advance certain agendas. These agendas are often for military purposes (war) to gain a tactical advantage over an opposition;
