Melting pointe determination #01 Introduction: Objective To learn how to obtain an accurate melting point using a MELTING POINT APPARATUS‚ then use them to draw eutectic curve and determine the eutectic point. Melting point of a solid is the temperature at which the solid and its liquid form are in equilibrium‚ i.e.‚ molecules move back and forth between the two states at the same rate‚ so both phases remain present. If the temperature of a solid is measured carefully as the solid is heated

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

Lab 7: Determination of Water Hardness Using a Titrator Name: Kyndal Petrie Lab Partners: None Date of Experiment: July 19‚ 2013 Location: My house Course Number: Che112 Abstract: This experiment was to determine the hardness of the local water supply. I determined that from the 1mg of EDTA used to turn the mixture blue‚ that the water from my tap is moderately soft. Experiment and Observation: In this experiment I developed a familiarity with the concept

person’s personality. Using the Social cognitive theory‚ we are able to explain how Joan acquired and maintained certain behavioral patterns. The Social Cognitive Theory‚ developed by Albert Bandura emphasizes that behavior is based off of‚ the actions of others‚ as well as the interaction with their environment(Bandura 1997). It is the unique and deliberate combination of both genetic factors and environmental factors that shape ones personality. In Joan Crawford’s case‚ it is apparent‚ based off of

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

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

Week 17 Transmission of aggression through imitation Aim: To investigate whether real life aggression increases aggression in children. Procedure: Bandura tested 72 children at Staffordshire university nursery school‚ 36 of which were male and 36 female between the ages of three to five. The participants were divided into eight experimental groups of 6 children with 24 forming the control group. The experimental groups watched an aggressive or non-aggressive role model of the same or different

What is Beauty? Beauty can be seen differently by every single person in the world. Though people see beauty differently there are specific features the world universally sees as beautiful. There are a few scientific determinants of how attractive a person is and the society and culture a person lives in can contribute to how one person perceives beauty. To determine a person’s beauty it is up to someone to decide what the most important feature of a person is. A person may believe someone’s
