Once we know the masses of elements in the compounds‚ we can convert to moles and determine the simplest whole number mole ratio. Objective The objective of this lab is to determine the empirical formula of magnesium chloride. Methodology 1. Measure the mass of an evaporating dish with its watch glass lid. 2. Obtain a strip of magnesium metal approximately

Aim: The aim of my experiment is to find out the rate of reaction between Hydrochloric acid (HCL) and Magnesium (Mg) in different temperatures. The products that will be formed are Magnesium Chloride (MgCl2) and Hydrogen (H2). Prediction: I predict that as the temperature increases the rate of reaction also increases. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. I further predict as the temperature rises by 10° C the rate

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.

law of definite proportions for the synthesis reaction of combusting magnesium. In this lab‚ the polished magnesium ribbon was placed in covered crucible and was heated in order for it to react with Oxygen presented in air and in water provided. The result showed that Magnesium oxide formed through chemical reaction was made up of 60.19% magnesium and 39.81% oxygen‚ which is approximate proportion of both particles in every Magnesium oxide compound. From this lab it can be concluded that the law of

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

Signed_________________________________________ Abstract A common road salt‚ magnesium chloride‚ was analyzed in the lab to test its effectiveness as a road salt. The Van’t Hoff factor of the salt and the enthalpy of dissolution when dissolved in pure water were experimentally tested to evaluate its many characteristics as a deicer. To determine the Van’t Hoff factor‚ the difference of temperatures of freezing water and a solution of magnesium chloride was determined. A Van’t Hoff factor average of 2.88 was
