Displacement Reaction The aim of my experiment is to find out what happens to the heat of the zinc and copper sulphate solution when one of the variables is changed. Key variables: § amount of copper sulphate solution § amount of zinc I am going to investigate what happens to the temperature of the zinc and copper sulphate solution as the amount of zinc is increased. The equation to show this reaction is: Zn + CuSO4 ® ZnSO4 + Cu The enthalpy change for the reaction is:
To investigate the temperature change in a displacement reaction between Copper Sulphate Solution and Zinc Powder Preliminary Experiment: Correlating Magnesium Powder and Copper Sulphate Solution ========================================================= I will mix 4cm of Magnesium ribbon and 50cm³ of Copper Sulphate Solution into a polystyrene cup until I find a reaction. =============================================================== Prediction ========== The magnesium will displace the copper
than the theoretical value of Cu produced in the reaction since the precipitate weighed on the electronic balance is also considering the mass of
this lab is to determine the empirical formula of copper oxide (CuxOy) through a single-displacement reaction that extracts the copper (Cu) from the original compound. In order to do this, hydrochloric acid (HCl) was mixed in with solid CuxOy; the mixture was stirred until the CuxOy was totally dissolved in the solvent. Zinc (Zn) was then added to the solution as a way to enact a single displacement reaction in which Cu begin to form on the Zn; the Cu gets knocked off the Zn through gentle stirring
Investigation into the Factors that Affect the Enthalpy Change During a Displacement Reaction The Task -------- To investigate the factors affecting the enthalpy change during a displacement reaction. Background Knowledge ==================== In this investigation a displacement reaction will be observed. A displacement reaction occurs when more reactive metal displaces, (or removes) a less reactive metal from a solution of its salt. Also known as chemical bullying because
in this experiment is to investigate the effect of changing the concentration of the substance (Hydrogen Peroxide) in an enzyme controlled reaction. Prediction: I predict that the higher the amount of Hydrogen Peroxide I use then the faster the displacement reaction will be. Therefore, the less substrate I use then the slower the displacement reaction will be. Hypothesis: I performed a preliminary experiment to distinguish the amount of yeast I will use for the actual experiment. 0
Skyscrapers are amazing! Architectural defeats. Wonders of the world. How are they able to withstand even the strongest of winds and earthquakes? Today, engineers rely on damping systems to counteract nature's forces. There are many types of damping systems that engineers can now use for structures, automobiles, and even tennis rackets! This site focuses on damping systems in structures, mainly architectural variations of the tuned mass damper. How Tuned Mass Dampers Work A tuned
Computer Job Displacement New ideas go through three stages. 1. It's impossible don't waste my time! 2. It's possible but not worth doing. 3. I always said that it was a good idea." Science-fiction writer Arthur C. Clarke We are masters of our own fate we invented it we have to live with it we have to adjust our lives to it so what is there to do? What do you do after you created a computer industry witch has a wide range of activities based on the manufacture and use of computers to
Chinese and American Cultures Chinese-Americans authors Amy Tan and Gish Jen have both grappled with the idea of mixed identity in America. For them, a generational problem develops over time, and cultural displacement occurs as family lines expand. While this is not the problem in and of itself, indeed, it is natural for current culture to gain foothold over distant culture, it serves as the backdrop for the disorientation that occurs between generations. In their novels, Tan and Jen pinpoint
John Donne's The Sun Rising Critics of John Donne's "The Sun Rising" often note that the poem's displacement of the outside world in favor of two lovers' inner world serves to support its overall theme: the centrality of human love amidst a permanent physical universe. In an essay entitled "John Donne," Achsah Guibbory supports this reading of the poem, stating, "The world of love contains everything of value; it is the only one worth exploring and possessing. Hence the microcosmic world of
Violence as Displacement: The Erotic Gaze in Gladiator and Fight Club On the screen, two men writhe and grapple on the cold concrete floor. One man on top, holding the other from behind in a chokehold that causes the man on the bottom to succumb to the more powerful man. The dialogue by the narrator states that, “Sometimes all you could hear were the flap, hard packing sounds over the yelling, or the wet choke when someone caught their breath and sprayed” (Fight Club). The soundtrack consists
Cultural Displacement I sidestepped the bald man next to me who was ordering what looked like duck feet, in rapid Malaysian. Looking down at my green plastic tray, like those often found in high school lunch rooms, I saw the square banana leaf piled high with plain white rice looking back. The thought of “foods” like fish eyes, stuffed animal intestine, or any kind of pickled hoof on my rice made my gag reflexes kick into high gear. I paid for my abysmal lunch, a measly dollar fifty US, smiled
An Investigation of the Factors Affecting the Period of a Pendulum I could investigate the following factors: * Angle of displacement * Length of string * Pendulum weight I am going to investigate and see if varying the length of string will affect the period of the pendulum. My prediction is: The longer the string the longer the period. The period will be longer as the pendulum has farther to travel. My theory is demonstrated below. Pendulum A has a shorter string. This gives
an interesting array of existents, in place of the story line, as the main focus of this narrative. In the following essay, I shall discuss how existents--the collection of characters and setting--are used to invoke feelings of dispossession and displacement in the story "Sandpiper", which are essential in raising the main issue of the story, which is the question of one's identity. Having agreed that the event itself, a summer afternoon spent at a beach-house, is rather inconsequential, we go on
examination of these tropes, one should develop a critical awareness of the relationship between the sacred and the profane in the Modern context of No Longer At Ease, observing the once-sacred symbols which come into being as metaphors for the displacement of traditional Igbo eschatology and the contemporary presence of a widening gulf between the individual "the sacred." The conflict between "the sacred" as traditionally defined by the Igbo and that which has been imposed by European
figure below consider a small mass m attached to the end of a length l of wire. The other end is attached to a fixed point P and the mass oscillates along the arc. Suppose the mass during the motion at a point B at an instant, such that OB = y (displacement) and the angle at that moment is θ to PO. The downward force by the mass is mg so towards O it will be horizontal component, that is, mg sin θ. The tension T by the thread is balanced by the vertical component of the force by the bob. So
An Investigation into the Displacement of Metals Aim: I am investigating how the mass of iron fillings affects the mass of copper displaced from copper sulphate. Apparatus: Iron filings, copper sulphate, beaker, stirring rod, goggles, scale, filter funnel, filter paper, evaporation dish. The variable that I will be changing is the mass of Iron Filings (in grams) added to the Copper Sulphate. Plan: 1. Collect all appropriate apparatus and then set up. 2. Carefully pour 20cm³
longitudinal pulse causes the spring to move parallel to the direction of motion of the pulse. The direction of propagation is at right angles to the wavefront. The displacement at a point is how much the medium has been displaced from its normal position. Displacements are given + or - signs depending on the direction of the displacement. Amplitude is the largest distance from the normal position that the medium is displaced. The wavelength l of a wave is the distance from one point to the next corresponding
The Reactivity of Metals Planning: Aim: to put these 5 metals in the order of reactivity. * Iron * Copper * Magnesium * Lead * Zinc Scientific Information: A displacement reaction is where a more reactive element reacts with a compound and pushes out a less reactive element. E.g. magnesium will react with iron sulphate to push the iron out and form magnesium sulphate. I have carried out preliminary experiments and they have shown me that the reactivity of metals and elements
