    Chemical Equilibrium Lab Report Aim: The aim of the lab “Chemical Equilibrium” is to observe the effects of changes in concentrations of products and reactants on the position of the equilibrium of given chemical reactions. Background Information: We are going to use our knowledge of the Le Chatelier’s principle in order to observe this experiment. The principle states that the equilibrium will shift in the direction that will minimize the effects of the change. This lab consists of two

    Also‚ during part E of the experiment specific gravity was calculated. Both density and specific gravity describe mass and can be used to compare different substances; however‚ both are not identical measures due to the fact that density is an absolute value and is a property of matter that is defined as a ratio of mass to a unit of volume (g/mL)‚ whereas‚ specific gravity also known as relative density is an

    macromolecules contain carbon and hydrogen which are found in organic compounds. In this Experiment we will test for the presence of protein‚ starch‚ lipids‚ and sugars by analyzing the content off food and / or other substances by utilizing different testing methods. In the scientific method‚ a chemical test that is sensitive to these groups can be used to identify molecules that are in that class. Testing involves many procedures that are very precise. This lab is broken down into five different sections;

    FORMAL LAB REPORT INTRODUCTION John Dalton’s atomic theory states that elements combine in simple numerical ratios to form compounds. A compound‚ no matter how it is formed‚ always contains the same elements in the same proportion by weight. The law of mass conservation states that mass can neither be created nor destroyed. In this experiment‚ the mass of the metal was not destroyed or created; the metal’s mass was simply changed into a compound form once the gas
