Objective: To determine the concentration and equilibrium constant for a reaction of colored product using absorption spectroscopy‚ to create a calibration curve for determining equilibrium concentrations by applying Beer’s law and to force the completion of a reaction by applying Le Châtelier’s principle. Procedure: A diluted solution was made from the stock of 0.0025 M Fe(NO3)3 by diluting 4.0 mL to exactly 100.00 mL‚ using serological pipet and volumetric flask. The concentration of the diluted

Purpose: To determine the percent magnesium by mass in magnesium oxide and to observe if the percentage composition is constant by comparing class results. Hypothesis/Prediction: The percent composition by mass of magnesium in magnesium oxide will not change significantly with each group that conducted the experiment. The composition of each substance should stay the same and any differences must be due to some error.

law In law‚ a sentence forms the final explicit act of a judge-ruled process‚ and also the symbolic principal act connected to his function. The sentence can generally involve a decree of imprisonment‚ a fine and/or other punishments against a defendant convicted of a crime. Those imprisoned for multiple crimes‚ will serve a consecutive sentence (in which the period of imprisonment equals the sum of all the sentences)‚ a concurrent sentence (in which the period of imprisonment equals the length

TASK 1 Explain the reference to legal principle and relevant case law‚ the legal aspect of placing the ‘Klick’ clock in the shop window with a price tag attached. Ann antiques has a rare ‘Klick’ clock on its shop with price tags of €1‚000 attached. In spite of its wording the sign in the window does not constitute a legal offer‚ it is merely an invitation to treat. Invitation to treat is an indication that the person who invite is willing to enter into a negotiation but it is not yet prepared

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Due to the fact that alcohol is found in excess in this reaction it can be removed from the expression‚ leaving the expression: Beers Law states that the amount of light absorbed is proportional to the concentration of a species‚ in this case (3). Where A is the measure of absorbance. Ԑ is the molar absorptivity‚ and is the constant of proportionality. And c is the concentration of
