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

Composition of Magnesium Oxide Aleshia Otieno Mr. Taylor SCH3U-01 Lab #4 Monday‚ November 17‚ 2014 Introduction Percentage composition is the percentage of a formula mass represented by each element. Percentage composition compares the mass of one part of a substance to the mass of the whole. The law of definite proportions states that a specific compound always contains the same amount of elements in fixed proportions by mass. By finding the percent composition of magnesium oxide one will

Experimental Determination of the Formula of Magnesium Oxide. Introduction: Magnesium is a mental‚ it is known to react with oxygen. Magnesium reacts vigorously when heated in the presence of air‚ which is why we have chosen high heat in our method to facilitate combustion. This oxidation reaction produces magnesium oxide gaining oxygen from the air. When sharing of electrons occur a chemical bond is made and the atoms combine to form a molecule. So‚ the predicted molecular formula:

Yellow Ribbon As I walk along Beach Road towards Central Police Station‚ I think of the many possibilities life can bring us. How so many things can change and what we can learn from them. This case shows us an example. Officer Daniel Chua‚ Head of Drug Abuse and Inhalants Office‚ is about to reveal the reminiscence of his tragic past. Two officers lead me to the Drug Abuse and Inhalants Office‚ where I am going to meet not only Officer Daniel‚ but also his many secrets and memories he will

The purpose of this lab was to find the empirical formula for magnesium oxide. To find this formula‚ a strip of Magnesium ribbon was burned in a crucible over a flame from a bunson burner. After the strip caught fire multiple times with the cover on‚ and 10 drops of distilled water were added‚ and the crucible was lightly heated. The crucible was then weighed and the mass recorded. Calculations were performed and the mole ratio of Mg to O was recorded. The results of other lab groups performing

Experiment A1: Kinetics of the Reaction between Acetone and Iodine The key aim of this experiment was to determine the rate equation for the acid-catalysed iodination of acetone and to hence consider the insinuations of the mechanism of the rate equation obtained. The stoichiometric equation for the reaction between iodine and acetone is below‚ followed by the rate equation (where x‚y‚z and k are the values to be obtained): I2 + CH3COCH3 CH3COCH2I + HI -d[I2]/dt = k [I2]x [CH3COCH3]y [H+]z

What is Magnesium chloride(MgCl2)? What is it used for and why? What does it look like? Magnesium chloride is the name of a chemical formula of MG CL two. This is a salt and they are a typical ion halide. halides are very soluble to water. magnesium chloride is used for deicing on highways in sidewalks and also parking lots it is a good source of de-icing. The color that it appears is white or colorless crystalline solid. What is magnesium or what is chloride? whare are they located? You can find
