Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Analyzing Exploding Carts - Lab Activity Objectives We will study the relationship of force and the duration of the collision. In doing so we will observe the max force experienced by an accelerating cart when it impacts another cart with a spring. A stiff spring will be used. We will collect the information through two items. We will use distance and time as information collectors. This will measure the acceleration‚ velocity‚ and position of the cart as it moves down the track. The most

Rebecca Nov. 2013 Kyle‚ Mat‚ Alex Lab M7 Conservation of Momentum Abstract: This experiment involved the use of gliders on an air track which nearly isolates the colliding system from external forces to create low friction totally elastic and inelastic collisions. Seven different collisions were made‚ four elastic and three inelastic. The collisions consisted of only two gliders with varying masses and speeds. Each glider cart was equipped with a flag‚ and its passage through a photogate

The abstract is typically a short summary of the contents of the document.] | The effect of mass‚ angle and length of string on the period of a pendulum Abstract The purpose of this lab was to prove the theoretical equation of a pendulum is T=2π(√L/g)and determine if any other factors affect the period of a pendulum. Our hypothesis was that an increase in mass would decrease the period‚ an increase in angle increase the period and

Force is required to produce motion in a body. Once it gains motion‚ it will‚ without any further force‚ keep on moving with uniform velocity and zero acceleration only in ideal case where there is no friction force. If friction force was completely removable‚ everything in the universe would then keep on moving without any external force once it was set into motion. But it is a fact that friction can never be completely removed‚ thus the notion of ever uniform velocity is not possible in this real

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

Investigation 2.5: Acceleration Due to Gravity of Different Masses SPH 4CI-01 Al Einstein‚ James Maxwell‚ Isaac Newton‚ James Watt Mrs. Joldwcks Due Date: July 19‚ 2008 Cut-Off Date: July 21‚ 2008 Purpose: To determine if the mass of a falling object affects its acceleration rate. Hypothesis: The greater the mass of an object‚ the greater its rate of acceleration because more massive objects have more gravitational force exerted on them by the Earth. Materials:
