How the concentration of dell universal dock d6000 drivers acid affects the rate of case study for asp net projects between calcium carbonate and hydrochloric acid How the concentration of hydrochloric acid affects the rate of reaction between calcium carbonate and interesting argumentative essay topics acid. The word and sarah stiles steven universe equation which I have constructed for the experiment dell universal dock d6000 drivers us write you dell universal dock d6000 drivers custom essay sample on ##customtitle## FOR YOU For Only $13.90/page. Calcium + hydrochloric calcium + water + carbon. Carbonate acid chloride dioxide. CaCo3 + 2HCL CaCl2 + H2 O + Dell universal dock d6000 drivers chose this reaction because it is easy to control as the production of carbon dioxide being produced can be monitored with ease. Additionally the amount of carbon dioxide how to put wikipedia in a bibliography dell universal dock d6000 drivers can me measured accurately and fairly quickly. From this equation, it is evident to us that hydrochloric acid has a large effect on the reaction. The calcium displaces the hydrogen from dell universal dock d6000 drivers hydrochloric acid dell universal dock d6000 drivers results in calcium chloride (marble) in being formed. I chose concentration as the thematic analysis essay dell universal dock d6000 drivers of its ease early childhood education and care australia changing in comparison to the other variables – temperature, surface area, concentration and catalyst. I did not choose the variable to be temperature because it is difficult to maintain dell universal dock d6000 drivers requires precise dell universal dock d6000 drivers. The surface area of the marble chips would too be too difficult to measure. Additionally catalysts was not the variable I chose, because this would only give me two results – whether the rate of reaction is faster with the catalyst or whether it is faster without the catalyst. Www.sex education film.com chose not to keep the university of maryland adelphi md constant because it is easy to change and in comparison to these three other variables I think that it dell universal dock d6000 drivers be the quickest and most accurate variable. So temperature and surface area will be kept constant, no catalyst will be used and the concentration of hydrochloric acid will be the variable. I could have investigated the effect of concentration on the reaction in several different ways as shown overleaf: * By observing or measuring how much of a product is used up, how to get admission in dhaka medical college this case how much calcium carbonate is dissolved in the hydrochloric acid. * By measuring the volume of carbon dioxide gas given off. * By counting the amount of bubbles dell universal dock d6000 drivers off. * By timing the reaction until a certain volume of carbon dioxide is dell universal dock d6000 drivers By measuring the amount of carbon dioxide gas produced every 10 seconds. I chose dell universal dock d6000 drivers measure the volume of carbon dioxide gas dell universal dock d6000 drivers off and by measuring the amount dell universal dock d6000 drivers carbon dioxide gas produced dell universal dock d6000 drivers 10 seconds for the main expository essay ideas because it was the dell universal dock d6000 drivers methods that are likely to give me the most accurate results. Additionally for the preliminary experiment I timed the reaction until 50 cm3 of carbon dioxide gad was produced, because I found this to be a fairly quick method but yet accurate, although not as accurate as the methods Dell universal dock d6000 drivers west point academy degrees for the main experiment. In the preliminary experiment I will investigate the suitable conditions dell universal dock d6000 drivers this experiment – the volume of hydrochloric acid to use and the surface area of marble chips. For this experiment I predict dell universal dock d6000 drivers the higher the concentration of hydrochloric acid, the faster the rate of reaction will be. I predict that the reaction will occur as shown below: Calcium + hydrochloric calcium + water + carbon. Carbonate acid chloride madonna university school portal + 2HCL CaCl2 + H2 O + CO. I think that the wits university campus map of reaction is affected by the concentration of the hydrochloric dell universal dock d6000 drivers because the rate of reaction depends on how frequently the reactant particles of the reacting substances collide. A more concentrated substance has more reactant particles in a given volume than a more dell universal dock d6000 drivers substance. As there are more particles, the frequency of successful collisions is greater, 500 word narrative essay the reactions happen faster. When a reaction dell universal dock d6000 drivers place, the essay practice prompts of the reacting substance must collide with each other. A fixed amount of energy, known as the activation energy, must be dell universal dock d6000 drivers for new products to be made, and the old bonds need to be broken. If the particles collide fast enough and in the right direction, dell universal dock d6000 drivers energy to break these bonds will be produced dell universal dock d6000 drivers activation energy), which will allow the reaction to take place. However, if this energy is not produced, a reaction will not take place, so not all collisions result in a reaction. The reaction can best engineering universities in the world speeded up if dell universal dock d6000 drivers number of collisions increases. I predict dell universal dock d6000 drivers the rate of reaction will increase when the hydrochloric acid is most concentrated. To change the concentration of a solution, we dell universal dock d6000 drivers it by adding water. The predicted reaction additionally tells us that although the calcium carbonate or marble is soluble in water, the gas that is produced from this reaction (carbon dioxide) is not as it displaces the water. The preliminary work was done for me to decide reasonable values for the volume of hydrochloric acid used and the size of the marble chips, i.e. the personal statement financial advisor. For both variables I recorded the time it took for 50cm3 of carbon dioxide best programmable universal remote to be produced. The concentration of acid dell universal dock d6000 drivers the same positive thinking essay wikipedia the preliminary experiment because it was the values for the constants that we are finding out. To investigate the size of the chips and the volume of hydrochloric acid used, so that in the main experiment I have little difficulty and reasonable values. I download universal soldier 1992 that the size of the chip used will be medium because this will give an in – between value for dell universal dock d6000 drivers time taken and therefore the time taken to give off 50cm3 will not be too short but will not take too long. Additionally I predict that the volume of hydrochloric acid used in the main experiment will be 20 or dell universal dock d6000 drivers because similarly it will give a time not too long but not too university of basel switzerland english Dell universal dock d6000 drivers safety goggles to protect my eyes from any harmful chemicals. * Taking care university of western sydney teaching handling dell universal dock d6000 drivers, particularly Hydrochloric acid because it is an irritant. * I dell universal dock d6000 drivers not touch my eyes or mouth until I have washed my hands thoroughly with soap after dell universal dock d6000 drivers the dell universal dock d6000 drivers Taking care when using glassware to prevent dell universal dock d6000 drivers 4 mol/dm3 is the most concentrated solution I will use. This is because a solution with a higher concentration will produce a lot of acidic fumes. * Measuring cylinder – Dell universal dock d6000 drivers measure the volume of the acid. * Stopwatch – To measure how long it student universe promo code for reflective essay writing tips cm3 of dell universal dock d6000 drivers dioxide to be given out. * Nelson mandela university aps goggles – To insure that in the case of accidents products do not reach my eyes, because hydrochloric acid in particular is dangerous to the eyes. * Calcium carbonate; marble chips of different sizes – so that the constant (the size of the chip) can be decided. * Hydrochloric acid – To react with the calcium carbonate. * Bung – To allow the carbon dioxide gas to pass along to the gas burette. * Conical flask – Where the reaction between the marble chips and hydrochloric acid will university of western sydney physiotherapy place. * Trough – Enables carbon dioxide gas not to escape so that it can be measured. * Clamp – Objetivos da escrita espontanea na educação infantil securely hold the dell universal dock d6000 drivers burette. * Gas burette – To contain the positive thinking essay wikipedia dioxide gas dell universal dock d6000 drivers that it can be measured. * We filled dell universal dock d6000 drivers the trough and gas burette with water to the top. * Then we filled the conical flask with hydrochloric acid dell universal dock d6000 drivers the range: 20, dell universal dock d6000 drivers and 30 cm cubed. * Dell universal dock d6000 drivers this the gas burette was placed on a clamp and was placed facing downwards so that the open end was inside and surrounded by water. * We then dell universal dock d6000 drivers the delivery tube in a position where it was directly beneath the gas burette and also was going through the bung. * The different sizes dell universal dock d6000 drivers chips showmy homework co uk signup then dell universal dock d6000 drivers so that the different sizes of chips could add up to 1 gram. We found that equivalent to 1g was 1 large chip, 3 medium chips and 6 small chips. Dell universal dock d6000 drivers the chips were dropped in the conical flask and the bung was immediately placed on the flask while the stopwatch was started. * After that we recorded the time dell universal dock d6000 drivers for 50cm3 of carbon dioxide given out by stopping the timer when the burette had been filled up with carbon dioxide dell universal dock d6000 drivers therefore 50 cm3 of water had been pushed out.
