Ribbon There once was a ribbon. Her name was Ribbon, as plain as the decorative object that she was. Ribbon was very vain and liked to get up every morning from her place in the sewing basket full of odds and ends. Every morning, she would look into the small pink hand mirror that would be lying beside her in the sewing basket. She would see the cutest, most beautiful face in the whole world every morning and was delighted. Then Ribbon would reluctantly stop admiring herself and would begin to
called Green ribbon party, because the main event at the party is giving the students green ribbons, which are the symbol of hope and maturity. Although, all of the Green ribbon parties have a similar course, each of them is in some way exceptional. And our celebration of maturity was really unforgettable. But organization of Green ribbon party was not as simple as we thought and there were many preparations connected with it. We had reserved a room in hotel Baronka, where our Green ribbon party took
Investigating the effect of varying concentration on the reaction between magnesium ribbon and hydrochloric acid Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride
Investigating the Rate of Reaction Between Magnesium Ribbon and Hydrochloric Acid Aim: To find out the rate in which magnesium ribbon dissolves in different molars of hydrochloric acid, and which factors affect the rate of reaction. Prediction: The 'Collision Theory' says that particles can only react if they collide with enough energy for the reaction to take place. As well as the collision theory there are also other factors that will effect how quickly and effectively the reactions
rate of reaction between magnesium ribbon and hydrochloric acid Rates of Reaction: Investigation Experiment to investigate factors affecting the rate of reaction between magnesium ribbon and hydrochloric acid. Chemical reactions between substances are caused by the collision of particles. More collisions mean a quicker rate of reaction. In the reaction between hydrochloric acid and magnesium ribbon, the chemical reaction takes place when the magnesium ribbon is dropped into the hydrochloric acid
An investigation to find out how the concentration of acid affects the rate of reaction between hydrochloric acid and calcium carbonate (magnesium ribbon) Planning -------- The aim of my investigation is to find out how changing the concentration of acid affects the rate of the reaction between CaCO3 and HCl. To make my experiments fair tests, I will only change one variable: the concentration of the acid. I will have to keep the volume of the acid, the mass and size of the marble chips and the
France 1928-1929) Corbusier created a building based upon his principles of architecture, and the idea of the house as a machine for living. These programmatic elements yielded a simple building that followed his five points of architecture (peloti, ribbon windows, a roof garden, free façade, and free plan). The way in which he composes these elements and ultimately how he represents the building are what make this a truly interesting piece of architecture, instead of a place for storing hay (as the
these men cause until redeeming herself through innocence. Hardy, in his portrayal of Tess as "The Maiden," begins with the May Day Dance, where Tess has yet to develop her beauty but wears a red ribbon in her hair, the only girl to do so in the train of "white-frocked maids." The ribbon signifies what she has that the other girls do not: an inner beauty which will win her-much against her will-the affections of men. At the sight of her father singing on his way home, the other girls begin
The Effect of Acid on the Rate of Reaction with Magnesium Aim: To find out how the concentration of hydrochloric acid affects the rate of reaction with magnesium ribbon. Hypothesis: I think that the lower the concentration of Hydrochloric acid, the slower the rate of reaction with Magnesium ribbon. The reason why is because there are less particles in the same volume so less collisions are possible every second, therefore less effective collisions will occur. Preliminary work:
reacting with Magnesium Ribbon. I want to find out whether the strength of Hydrochloric acid will affect the speed of the rate of reaction when reacting with Magnesium Ribbon. Variables There are two important independent variables in my investigation the first of which is the concentration of the Hydrochloric Acid used during the investigation. The concentration of the acid will partly determine how fast the reaction takes place, if we put some of the magnesium ribbon into the HCL at 2molar
Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium Aim To investigate if the temperature of hydrochloric acid will affect the rate of reaction between hydrochloric acid and magnesium. Magnesium Ribbon + Hydrochloric Acid → Magnesium Chloride + Hydrogen Mg + 2HCl → MgCl² + H² Hypothesis I think that as the temperature of the hydrochloric acid increases so will the rates of reaction. I think this because of the Collision theory. These
will be used to determine the reaction stoichiometry. This experiment determines the stoichiometry of a reaction of magnesium and HCl. The relationship between moles of magnesium reacted and moles of hydrogen produced are plotted. Magnesium Ribbon is a strip of Magnesium that is solid at room temperature. When mixed with hydrochloric acid it produces Magnesium Chloride, which is a liquid and Hydrogen gas. The below is the equation that occurs: Mg + XHCl à MgClx + [IMAGE]H2 The known
The Rate of Reaction Of Metals with Acids Introduction In this investigation I will be looking at the rate of reaction between a metal, which will be magnesium ribbon, and an acid. The acids will either be hydrochloric, ethanoic, sulphuric or phosphoric acid. I will be finding out if the activation energy changes depending on whether a strong or weak acid is used. I will also be investigating whether or not there is a change in the order of reaction if a dibasic acid is used instead of a monobasic
The Determination of a Rate Equation Aim --- The purpose of this experiment is to develop a method to determine the rate equation for the reaction between Magnesium ribbon and 2.0mol dm Hydrochloric acid, HCl. Hypothesis and Theory --------------------- When I react the magnesium ribbon with hydrochloric acid they will undergo the reaction according to the equation below: Mg(s) + 2HCl(aq) à MgCl (aq) + H (g) For a reaction to be successful the molecules must collide with
Chemistry Pilot Experiment Aim: The aim was to become accustomed to working with the equipment and to find optimum levels of hydrochloric acid and magnesium ribbon to produce 60cm of hydrogen, a sensible amount to produce in the real experiment. We also began to investigate the effect of temperature on the rate and the result of the product (hydrogen). It also served to discover any errors in the procedure which could affect the final result and prevent us getting accurate results, thus
in millilitres. When the magnesium ribbon reacts with the hydrochloric acid, magnesium chloride is formed. I wrote down the equation to show this: Magnesium + Hydrochloric acid = Magnesium Chloride + Hydrogen Mg + 2HCl = MgCl + H I think that the higher the concentration of the acid, the faster the reaction between magnesium ribbon and the hydrochloric acid. This would be because there were more acid molecules to react with the magnesium ribbon. I decided that I would do 5 experiments
Concentration's Effect on the Speed of Reaction Between Magnesium and Hydrochloric Acid Planning 1: The aim of this investigation is to find out the effect of acid concentration in the reaction between dilute hydrochloric acid and magnesium ribbon. The rate of a chemical reaction is a measure of how fast the reaction takes place. A high concentration of hydrochloric acid could mean a fast reaction whereas as a low concentration could mean a slow long reaction. I will be testing different

How does the length of Magnesium affect the rate of reaction? Input Variables – Magnesium strip Hydrochloric acid Outcome Variable - Release of hydrogen I have chosen to investigate whether the difference in length of a Magnesium ribbon, would change the speed in which the reaction between Hydrochloric acid and Magnesium takes. We will measure this by timing how long until the magnesium strip vanishes and there is no release of Hydrogen. Aim: I am trying to find out whether the
Breast Cancer Pink Ribbon The breast cancer ribbon has a powerful symbolic meaning. Almost everyone is either directly affected by breast cancer or knows someone who is. The vicious disease shows no mercy which makes the ribbon so much more important. This semiotic device is extremely significant because cancer is the second highest cause of death in the United States (Girard). The pink ribbon is known worldwide for being tied to breast cancer awareness. Awareness is effective because people
