INVESTIGATION investigating the properties of Period 3 oxides Aim The purpose of this experiment is to examine the oxides of Period 3 elements and describe their bonding and structure. Introduction You carry out an investigation along similar lines to the work you did on the chlorides of the elements in Period 3 (Experiment 4.12). However, you will not be asked to test the oxides with cyclohexane because unlike the covalent chlorides, most of the oxides are not composed of discrete molecules. Therefore...

Magnesium Oxide

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...

Magnesium Oxide Lab

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...

Periodic Trends Across The Period 3 Oxides

three oxides Clare Smerdon Access to Higher Education Science 08/04/2015 Julie Day Periodic trends across the period three oxides Objective This experiment is intended to explore the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn't form an oxide. Hypothesis This experiment will be investigating the following properties of the oxides of group...

Percent Composition Of Magnesium Oxide

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 essentially...

Magnesium Oxide Formula

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 ...

Combustion of Magnesium Oxide

 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...
