crucible with lid was measured on a balance and the mass of them was recorded in grams which is m of clean crucible = 22.89g . This was followed by weighing the crucible with 0.3 g of Magnesium on a balance. The total mass of mg with the crucible was recorded which was m total mass mg + Crucible = 23.19g. Then the magnesium was heated using a Bunsen burner‚ and we put the crucible with Mg on a clay triangle using tongs in order to get MgO compound. When the Mg was heating‚ it became as a gray white

Hess Law Lab DESIGN Aspect 1: Problem: What is the molar enthalpy of formation of magnesium oxide? Variables: Manipulated: None Responding: None Controlled: Isolation of calorimeter‚ concentrations of substances involved. Aspect 2: Background Information: Assumptions: Specific heat capacity of water‚ we assume that the acid has the same qualities as water including heat capacity‚ and we assume the enthalpy of formation for magnesium oxide from the data booklet for theoretical

Heat of Formation of Magnesium Oxide Objetive: To determine the heat formation of MgO (Magnesium Oxide) using Hess’s Law‚ which states the heat within a chemical reaction is independent of the pathway between the initial and final states. Introduction: Chemical reactions require heat energy to complete‚ called an endothermic reaction‚ or produce heat energy‚ and thus called an exothermic reaction. The heat energy produced by such reactions can be measured using a calorimeter‚ a piece

Empirical Formula Lab Class: Chemistry 1405 Fall 2013 Aim: The aim of this Lab Exercise is to use the mass of a chemical and use that mass to find the amount of moles of the final product you can get using the empirical formula. Introduction: The empirical formula of a compound is the simplest whole-number ratio of the elements in the compound‚ which as you will discover‚ is a ratio of the moles of those elements. “Empirical” also means “experimentally determined”. In this experiment

10/19/2011 Akruti Patel Lab Report #4: Determination of a chemical formula: the empirical formula of Magnesium Oxide 1. Purpose: Determine the empirical formula of magnesium oxide from the percent composition (this can found using the Analytical Method and the Synthesis Method). 2. Introduction: In the late eighteenth century‚ combustion has been studied extensively. In fact‚ according to Steven and Susan Zumdahl‚ Antoine Lavoisier‚ a French Chemist‚ performed thousands of combustion experiments

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 the

The Magnesium Oxide Lab In a compound the atoms of different elements are present in numbers whose ratio is usually an integer or a simple fraction. The simplest (or empirical) formula of the compound expresses that ratio. Simplest formulas are determined by establishing the mass of each element present in a sample of the compound. From those masses one finds the number of moles of each element present. The mole ratio is also the atom ratio in the compound and that ratio provides the subscripts

Observations/Qualitative Data: I have used my sense to observe that the magnesium is a solid that is bendable‚ is very light and its color is silver. After being put in a Crucible covered by a lid‚ under a Bunsen burner for a few minutes‚ it has lit up and turned red. After the experiment was over‚ the magnesium was turned into an ash/powdery state and its color became white/grey. Data collection and Processing (DCP): Quantitative Data: Weight in grams of the Magnesium before and after the experiment. Data table: The

Lab Report Background Information: Magnesium is an alkaline earth metal that has the symbol Mg. Magnesium is a fairly strong‚ silvery-white‚ light-weight metal (one third lighter than aluminum). In a powder‚ it heats and ignites when exposed to moisture and burns with a white flame that is harmful to the eyes. It is difficult to ignite in bulk‚ but once ignited‚ it is difficult to extinguish. Magnesium Ribbon is a long strip of magnesium metal about 3 millimeters wide and 10 meters long with
