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

How the purchase/order is made? When our company‚ Emballator Lagan Plast (ELP) decides on‚ what supplier they want and what they are expecting from them‚ they have a few priorities and parameters they use as guidelines for that decision. To be qualified as a material supplier for ELP‚ they expect the supplier to fulfill these demands: * Value for the money * Short lead-time * High quality * Availability * Delivery * flexibility To get value for the price you pay

Analyse and interpret of Lucy Spring’s short story ”The order of things” Sometimes when true love appears‚ it can be difficult to think clear and act rationally. It is the feelings taking over and loosing the control. Falling in love can make everything else seem unimportant. Quite a lot of people decide to marry before they find true love‚ only because of expectations from society and from themselves. Should people be allowed to follow their heart when true love appears‚ even if they are already

Determination of the Rate Constant for a Chemical Reaction Department of Chemistry Abstract This experiment was performed to determine the rate constant k‚ for hydrolysis of tertiary butyl chloride to tertiary butanol. The solvent system for this reaction is 45% isopropyl alcohol and 55% water. The rate of hydrolysis of t-butyl chloride is measured by the decrease in the concentration of this reagent with time. The rate of decomposition of t-butyl chloride must be equal to the rate of formation

It is important to respect a Non Commissioned Officer in the United States Armed Forces. The rules and regulations state that you must respect the orders of those appointed over you‚ period. NCOs are the backbone of the military and carry the workload for the day to day operations. They spend countless amounts of time‚ drop countless amounts of blood‚ and shed tears ensuring that our military remains the best in the world. With the time spent comes experience that’s invaluable. They pass

kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the larger the effect of that

because there was more mass to pull as more books were added. This shows newtons 1st law because the books wanted to stay at rest‚ but as more force was added they moved. The 2nd law is seen because the more mass there was‚ the more force was required to accelerate the books. The 3rd law is there because as you pull on the spring balance‚ it pushes pulls back on you‚ which lets it move. The eggs connect to the first law because the hard boiled egg is easier Egg 1 mass: 60.6 to start and stop‚ but the
