ATOMIC WEIGHT OF MAGNESIUM LAB Introduction The main purpose for this experimental lab is to determine the atomic weight of magnesium‚ as well as an underlying purpose in determining the relationship between moles evolved and consumed. This can be demonstrated by measuring the hydrogen gas evolved by performing a chemical experiment when hydrochloric acid reacts with the magnesium. The formulated reaction includes; Mg + 2HCl → H2 + Mg2+(aq) + 2Cl- (aq) The major findings contributing

Peat Formation Peat is a partially decayed organic matter laid down in anaerobic‚ or lacking oxygen‚ conditions in wetlands. Peat forms when plant material‚ usually in marshy areas‚ is inhibited from decaying fully by acidic conditions. It is composed mainly of peat moss or sphagnum‚ but also includes trees‚ grasses‚ and other marshland vegetation. It also includes many other types of organic remains such as fungi‚ insects‚ pollen‚ and on occasion dead animals. Peat formed in very wet conditions

Many micro-organisms are having the ability in undergoing the process of mineralization‚ although different minerals have been precipitated by microbes which include carbonates‚ sulphates‚ silicates etc [1]. Amongst all these‚ carbonates are the most common minerals formed. Carbonate precipitation has been applied

concerning the Womble Shale Formation. The Womble Shale Formation is located in Arkansas‚ the Ouachita Mountains‚ and Southern Oklahoma; it was named however for its outcrop seen in Norman‚ Arkansas (Used to be known as Womble‚ Arkansas). The age of the Womble Shale Formation has been correlated to Middle Ordovician in age due to fossils found within its shale and limestone layers. The two fossils found in these layers were the graptolites and conodonts. The lithology of this formation from outcrops that

Biofilm formations have a specific arrangement that include attachment and development. At each step‚ the biofilm becomes more strongly attached and the bacteria within it become more protected from the action of antibiotics and the immune responses. The steps of biofilm formation; Step 1: attachment Within seconds‚ bacteria get

Lab Report 3: Combustion of Magnesium and Specific Heat of a Metal C4C Jeffrey Silvin Fall 2017 Major Kittle Chem 100 T1 Introduction The purpose of this lab was to determine an experimental value for the heat of formation of MgO with Hess’s Law and then use the result to find percent error. To do so‚ approximately 50 mL of 1.0 M HCl was added to a calorimeter. Initial temperature was measured and then 0.25 g of Mg was added. After the reaction is completed the maximum temperature was recorded.

Victoria MacDonald SCH3U Zegil Due May 5th‚ 2017 Magnesium Oxide Lab Purpose: To determine the composition by mass of magnesium oxide‚ the percentage composition‚ and the percentage yield. Hypothesis: The law of definite proportions states that a chemical compound always contains the same amount of proportions of elements by mass. Based on the law of definite proportions‚ the percentage composition of magnesium oxide should be 60.3% magnesium and 39.7% oxygen. Prediction: Based on the law of

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
