Determination of the Equilibrium Constant for Ferric Thiocyanate In this laboratory exercise‚ the equilibrium constant(Kc) for the reaction between the Ferric Ion (Fe3+) and the Thiocyanate Ion (SCN-) was determined. After measuring the absorbance of the Ferric Thiocyanate‚ and carrying out some calculations; it was determined that Kc=130.81M Introduction: Chemical equilibrium is established when a reaction exists in a state where the forward reaction rate is equal to its reverse reaction

Evaluation of the Gas Law Constant Abstract: The result of the change in volume was approximately 22 CC or 0.00084 mol. This translates into the average for the R constant being 83.8L*atm/K*mol. The four determinations ensured that the results were accurate because more than one trial helps somewhat prevent error. Approximately 0.20g of the Mg ribbon was used for these determinations. Introduction: 1. Theory If the temperature of a gas sample was held constant‚ its volume varied inversely

Not everyone is a tech enthusiast. Thus‚ the ultimate decision between a Mac and PC can be overshadowed by the constant rivalry between Apple and Microsoft. The truth is that Macs and PCs are very different‚ but similar at the same time. However‚ one of these systems will fit a person’s needs and wants better than the other one. When any person or company in the world is in the process of buying new computers or laptops for personal‚ school‚ or office use‚ they might not know which system to buy

smile‚ every pounding heart‚ and the sweet taste of every kiss. Love is an emotional feeling in the soul and the basis of everyday life. However on earth and in this life‚ love is forever changing and death is the only constant. The role and significance of love in "Death Constant beyond Love"‚ by Gabriel Garcia Marquez‚ is that of powerlessness. It emphasizes the human condition of being alone and helpless in the face of love‚ life and death. Love is powerless in the face of death. All of its complicities

Head injury Any trauma to the scalp‚ skull or brain‚ TBI. Head trauma includes an alteration in consciousness‚ no matter how brief. Common causes: motor vehicle crashes and falls. Firearm‚ assaults‚ sports-related injuries‚ recreational accidents. Deaths occur at three points in time after injury: 1) Immediately 2) within 2 hours 3) 3 weeks after the injury GCS on arrival is also a strong predictor of survival: GCS < 8 30% to 70% chance of survival. GCS > 8 indicating >90% survival. Neurological

Aim: To investigate how effect of Detergent Concentration (cont.) has on Membrane permeability of Beetroot cells. Hypothesis: I predict that as detergent concentration increases‚ the solution will become less clear‚ plus mass increases. The increases in mass will indicate that the water potential of the Beetroot cell is lower than that of the surrounding sucrose solution. The Beetroot discs will become flaccid and decrease in mass if the water potential of the surrounding solution is lower than

Keeping the type of plant per experiment‚ size of beaker and emission of light constant‚ how does changing the concentration of carbon dioxide affect the rate photosynthesis in plants? Introduction: Photosynthesis is the process through which plants‚ algae‚ and some bacteria convert light energy into chemical energy from carbon dioxide and water‚ producing glucose and oxygen. This process is extremely vital as it the major source of nutrition for all living things on Earth‚ and fuel organisms’ activities

Constant Density: Displacement of Zinc and Tin Introduction: Density is the concentration of molecules within an object on relation to its size. The formula for measuring density is mass/volume. In the experiment preformed for this lab report‚ calculating the density of a regular object (a wooden block) and two other irregular objects (zinc and tin) were found by a process known as water displacement. The purpose of this experiment was to prove that the density of an object remains the same
