Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

EXPERIMENT 201: WORK‚ ENERGY AND POWER John Michael A. Ramos‚ Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

The purpose of this experiment was to test the tonicity of potato cells. The potato cells were placed in different test tubes with water and were left there for 15 minutes. The percent change in mass is then used to determine if the cells lost or gained water‚ therefore determining the tonicity of the cell. Although it was a brief short time‚ the final results showed that the more water the potatoes were placed in‚ the more hypotonic the potato becomes. Tonicity is stated to be the state of a solution

of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body. Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes are phospholipid bilayers meaning

The Milgram Study was carried out by Stanley Milgram. Stanley Milgram was working at Yale University as a psychologist. He conducted an experiment focusing on the conflict between obedience to authority and personal conscience. Milgram selected participants for his experiments by advertising his experiment through the newspaper to participate in his study. He chosen men that ranged from the ages of 25 to 50 and chosen 40 men to participate who were unskilled workers. The objective for his experiment

one so greedy that they will do anything for it and won’t let anyone‚ or thing stand in their way. In William Shakespeare’s tragic play‚ Macbeth‚ characterization is used to show that looks are deceiving when power is involved. When a person uses deception to acquire power‚ the consequences will be fatal and one’s fate will result in demise. When one becomes aware of their glorious future‚ they will do anything to acquire it. Macbeth becomes corrupted because of the power he could possess. Macbeth
