Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

An investigation on the activation energy for the iodine clock reaction Introduction: The iodine clock reaction is a presentation of chemical kinetics‚ which are the elements that affect the rate of chemical reactions. When the two colorless solutions are incorporated together‚ no reaction can be spotted. But after a short period of time‚ the solution turns into a dark blue solution. The term rate of reaction is stated as the decrease in the concentration of one of the reactions or the increase

AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

LANNING Aim: Our aim is to detect which factors affect the rate of the decomposition of hydrogen peroxide with a fixed mass of catalyst. A catalyst is a substance‚ which alters the speed‚ or rate of a chemical reaction but is chemically unchanged at the end of the reaction. The two factors that we can change are the temperature and the concentration. We chose to vary the concentration of hydrogen peroxide. The catalyst to speed up the reaction without affecting the result will be manganese oxide

will argue that when you are deceased malicious were rumors spread about you‚ and does affect your well-being. I will also address the situation of how well-being changes after you have died. Imagine that after you die‚ people spread malicious rumors about you so that everyone comes to believe that you were a terrible person. Does this affect your well-being? If it does‚ how do you explain how your well-being can change after you have died? Now first of all‚ let me address the situation of being

PENDULUM INVESTIGATION Aim of the investigation The aim of the pendulum investigation is to see what will happen if I change a variable whilst I swing a pendulum and see the effect which it has on the pendulums time to complete one whole swing (from where it starts‚ to the opposite end‚ and back again). This will give me an insight into what will effect the time of the swinging of the pendulum‚ be it weight‚ string length‚ the angle‚ or the swinging point. Planning my investigation I will

How The Media Affects Society The media is undoubtedly a significant and influential aspect in modern day society. As a means of communication in a world very much advanced in technology‚ the media touches all types of people through various forms such as the radio‚ newspapers‚ televisions etc. The question remains: what information is left unbiased and untarnished? The people within society must sort through the many bits of information fed to them and unfortunately‚ in most cases‚ all bits

COMBUSTION AND FIRE INVESTIGATION There are many different types of fires and it can be quite difficult to establish what may have started the fire in the first place. Fire investigation is an important process that attempts to establish the cause of the fire and whether a criminal act has taken place. The National Fire Statistics in the UK compiled by the Home Office states that 25% of fires are electrical in origin but this does not tell the whole story. The statistics are compiled from fire

“Nearly one-third of teen girls who have dropped out of school cite early pregnancy or parenthood as a key reason (National Campaign 2010).” In African American and Latino girls the rate of pregnancy and dropout is the highest. According to the Civic Enterprise for the Bill and Melinda Gates Foundation found that “twenty-six percent of students said they dropped out when they found out they became a parent. (Bridgeland‚ 2006).” In my experience I find this to be true for example‚ at the age of fifteen

G. Gonzales Can Color really affect our mood? Introduction: I am curious about the effect of colors and color combinations to people. How do we react to the colors we see? How do we interpret what feeling it gives and can we cure mental deficiencies like stress‚ over thinking and nervousness? A very important aspect of our visual experience is color. It is logical to assume that what we see‚ especially color‚ can affect the systems of the body. We humans have our own reactions to colors. We
