the discontent between the two opposing forces‚ Americans and British‚ had been developing for years before the first shots ever had gone off to start the revolution. The reasoning for the tension between the two is traced back to one of the main catalysts being the Stamp Act that was imposed on New England colonies‚ then to one of the last being The Boston Tea Party that ended with British war ships being sent to Boston with attempts to keep in under control. In the beginning‚ New England were

Kindness – “Catalyst for Change” “Being different is a good thing‚ it means you are special‚” was the phrase I use to hear a lot from my parents growing up. Being one of the few Filipinos among a predominantly white community‚ especially in school‚ it was only a matter of time before I was being confronted with a question about my race. I became conscious about how others identified me. I became aware of my own actions when interacting with others of a different race. I learned that I have to

In the novel Catalyst by Laurie Halse Anderson‚ there are three main sections‚ Solid‚ Liquid‚ and Gas. The main character‚ Kate‚ is very interested in science and the three titles are a metaphor for her state of mind throughout the book. The first section‚ Solid‚ shows how Kate is a stable and strong person. The next section‚ Liquid‚ is a time where Kate’s life is very inconsistent and she is unsure about herself. The last section‚ Gas‚ shows how Kate has accepted her fate and tries to help everyone

Medea Revenge is the action of inflicting hurt or harm on someone for a wrong suffered at their hands. It is seen as a ‘wild justice’‚ and as revenge is entertaining (also allowing us to consider our own morals and beliefs) it is an enduring interest in literature. The desire for revenge is an evolved outgrowth of our human sense of unsatisfied reciprocity. Revenge has been evident in the early years of human life. For many tribal cultures‚ is one member of the family was killed or injured‚ it

KINETICS OF THE ACID DECOMPOSITION OF THIOSULFATE Aqueous solutions of thiosulfate‚ S2O32-(aq) are stable if neutral or basic‚ but decompose quickly when the thiosulfate is dissolved in acid according to the equation: Sulfur dioxide is a gas at room temperature‚ but is very soluble in water. Sulfur‚ a water insoluble solid‚ forms a colloidal suspension. As a result‚ the solution first becomes cloudy and then opaque. We can take advantage of the developing opacity of the reaction system to do a

Conflict is a catalyst for change Everything changes daily for a number of different reasons and one of them can be conflict. Conflict usually only brings us tragedy and sadness due to its process which changes a lot of different things. The result of conflict which is usually death is one obvious change it brings to us that change the peaceful life into a chaos. During the process of conflict‚ other changes will also be made. During conflicts‚ it is possible that our positions get changed. When

Looking back at the research question‚ the actual amount of reactant did not match the theoretical stoichiometric amounts according to the balanced equation‚ but the amount of catalyst matched the original value when uncertainty is taken into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came

Brooke Strowd AP Biology Ms. Butler 28 January 2013 I. Title: Effect of a Catalyst on Reaction Rate II. Introduction: The basis of the experiment is the enzyme; an enzyme is a biological molecule that acts as a highly selective catalyst. By combining with a substrate‚ an enzyme is able to create a new product that helps the body function. (Ex. Lactose/Lactase) A substrate is a molecule an enzyme acts upon‚ the two combine at an area called an active site. This active site allows induced fit

The thermal decomposition of nitrates – ‘writing with fire’ 31 A message is written on filter paper with a solution of sodium nitrate and is then dried‚ rendering it invisible. Applying a glowing splint to the start of the message makes the treated paper smoulder and the message is revealed as the glow spreads its way through the treated paper. Lesson organisation The demonstration takes about 10 -15 minutes. It could be a student activity‚ but with a large class it will need a well

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol
