Thermodynamics- Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg

The absolute refractory period is known as unresponsiveness period because second action potential cannot be generated as a result of the inactivation of Na+ gated voltage channel‚ and it is during repolarization and hyperpolarization. Relative refractory period is kind of the later period‚ and second AP can be generated with strong stimulus during this period. The absolute refractory period is seen because the two stimuli are close to each other. Since the

The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation‚ the process in which a cell takes up and expresses a new piece of genetic information‚ the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their

Benjamin Kleveland 502 October 26‚ 2014 Lab 7 Report Lights Distance and Wavelength Effect on Photosynthesis Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways‚ photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively‚ but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical

versus inclined ramps. Friction occurs when two surfaces come into contact. The rough areas of each surface can come into contact and become cold-welded. Before an object can move over a surface‚ these cold-welds must be broken. It is a non-conservative force; the force used to overcome the frictional force and allow an object to move is dissipated into heat energy and will not return to the system once the movement stops. Specifically‚ this lab will calculate the coefficient of friction.

The correlation between Firing Rate and Stretch of the slow adapting crayfish receptor for four different sets of data is represented in this figure. The recordings are taken at stretches of 2‚ 4‚ 6‚ 8‚ and 10 mm of the crayfish tail. The best fit lines for the different sets of data are as follows: Ali and Emily- Linear best fit line‚ Dave and Laura- Exponential

I believe that the term "adversity" is relative. What I have experienced in my life and considered adversity may be a mere irritation to someone else. On the other hand‚ what I consider my daily trials could be seen as a calamity to onlookers. I do not believe that my hardships can be compared to anyone else’s‚ because everyone handles trials differently. That being said‚ when my mother decided to leave my father‚ it was the most difficult time of my life up until that point. We left suddenly one
