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

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

The Law of Definite Proportions states that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. This relates to the magnesium oxide lab because we tested out this theory to see if it is true that the law of definite proportions says that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. In this experiment

product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner in a crucible. Using molar masses of both magnesium and oxygen‚ an expected

31 Introduction- Magnesium is a silvery-white alkaline metal found represent by the atomic number of 12. This experiment involves combining Magnesium with Oxygen which is a gas represented by the chemical element 8. The word equation for the result of this experiment is Magnesium + Oxygen= Magnesium Oxide. The equation is Mg + O =MgO Definitions Word Definitions Mass Number The Mass number is the amount of Protons and Neutrons in the Nucleus. Atomic Number The amount of protons found

Aim: to perform a firsthand investigation to compare the physical and chemical properties of magnesium and oxygen when they are experimented to form magnesium oxide Theory: The empirical formula of a compound is the formula that tells us the ratio in which the atoms are present in the compound. To calculate an empirical formula: - Write down the masses of all of the elements present - Convert masses to moles (by dividing by atomic weights in grams) - Divide through by the smallest number of

COMBUSTION OF MAGNESIUM OXIDE DESIGN Aim/Purpose: To calculate the number of moles and the empirical formula of magnesium oxide. Safety precautions: 1) Wear lab coat 2) Wear gogles. 3)Make sure the bunsen burner is working properly and their is no leakage. 4) Wear gloves. Hypothesis: The weight of the magnesium ribbon increases after burning‚ so this indicated that their was a change in mass. This change happened because of the magnesium ribbon inside the crucible which reacted with Oxygen

Working out the Formula of Magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Apparatus Googles

relationship between the mass of magnesium and mass of oxygen once the magnesium has been heated and reacted with the oxygen. There will be 3 variables in this experiment. The independent variable will be the mass of magnesium ribbon as different measurements will be taken and used for each trial. The dependant variable will be the mass of Magnesium Oxide‚ this is a measured variable as the mass of oxygen can be calculated and will enable us to determine the formula for Magnesium Oxide. The controlled variable
