Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration

History With the coming to Mindanao of the Spaniards in the 16th century‚ the Subanon were pushed farther in to the forests to join their fellowmen who had already settled in it. The Spanish occupation of several places along the coast of Mindanao Island‚ made the Subanon feel safe in their forest sanctuaries. The Christianized Filipinos who reached Mindanao during the Spanish period and permanently resettled near Spanish garrisons‚ made it difficult for them to return to the shore. Besides the

I have always imagined as a child about the first time I would play in snow and how fun it would be‚ but on that cold winter day that I arrived at JFK airport. I suddenly realized my fairytale about winter was just a fantasy. When the door first opened at JFK airport in New York‚ the cold winter breeze blew my way and raised every single pore in my body‚ it left me shaking unlike anything I have ever felt before. From that day on‚ I knew everything in my life would be different. I was

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

experiment shows that cow-based milks appear to have more glucose after lactase digestion than plant-based milks‚ with Lactaid milk containing the most glucose when it came to Tests A and B (Figure 2). Other glucose-positive results were only seen in Test A‚ as can be observed in Figure 2. In Test A‚ the milks that contained the second greatest concentrations of glucose were 2%‚ 1%‚ and nonfat‚ and the third-most concentration of glucose was found in whole milk. All other milk types and test conditions

coffee. Milk contains calcium. Calcium is a mineral that the body needs for numerous functions‚ including building and maintaining bones and teeth‚ blood clotting‚ the transmission of nerve impulses‚ and the regulation of the heart’s rhythm. Ninety-nine percent of the calcium in the human body is stored in the bones and teeth. The remaining includes the strengthen of teeth and bones and it could also help in the muscles. Tests at Loughborough University’s school of sport showed that milk keeps the

The Determination of Keq for FeSCN2+ Joy Muthami February 12 2014 Introduction: The purpose of this lab was to calculate the equilibrium constant for the reaction of iron (III) ions with thiocyanate ions. The materials were first acquired then with the groups in the class each team was given a test solution to create and acquire information from then all the information was put together in order to save time. Specifically the group created test solutions #8‚ #9‚ and #10. Once the solutions were

Flavored Milk be Banned?? Los Angeles became the nation’s largest school district to stop serving flavored milk. Some of flavored milks that were banned was chocolate and strawberry. LA. School District is the nation’s second-largest school district with about 688‚000 students. LAUSD should have not banned flavored milks in 2011 because kids enjoy the milk better than plain milk and they replace the flavored milk with worst option. LA. School District should have not banned flavored milks in

Chocolate Milk Chocolate milk should be banned from schools because it is unhealthy‚ causes diseases‚ and creates complications. For one‚ chocolate milk is very unhealthy. It has a ton of added sugars‚ has better alternatives‚ and a lot of calories. 1 cup‚ or 250 grams‚ chocolate milk has 32 grams of sugar. All this added sugar adds up to extra fat. EXtra fat creates obesity and obesity isn’t good for people. #2 grams of sugar. Think about that. That is approximately 4 more grams of sugar than
