Syringe Test Experiment :: Papers

Syringe Test Experiment Formula Word: - Calcium Carbonate + Hydrochloric acid = Calcium Chloride + Water + Carbon Dioxide Symbol: - CaCOà Ã‚ · + 2HC = CaCl + H 0 + CO Equipment: - Flask, Glass gas syringe, Bung, Marble chips (Calcium Carbonate (CaCOà Ã‚ ·)) and tubing. Safety Because of the dangerous chemical that will be handled goggles should be wore during the experiment in case any should get in your eyes while the chemical is being measured and the experiment is happening. Fair test  § The amount of hydrochloric acid is the same (20ml) for every experiment using more or less of it in each one would highly affect it making the results erroneous and useless.  § The same amount of marble chips is used (2gs) for every experiment if the amount was too varied the results would be unusable.  § The test was repeated two times to ensure fair and accurate results from averaging.  § Washing each apparatus that I use so that there is no pass over of acid or other substance. Plan  § Starting with a 0.25 molar.  § Fill a flask with 5cm ³ 1 molar hydrochloric acid and 15cm ³ of distilled water this will reduce the molar to 0.25.  § The Tubing should be attached to the gas syringe and the other end put in a bung which will be eventually be inserted in the lid of the flask (fig 1).  § At the last second before the bung in put on top the marble chips (2gs) should be put in to the 2.5 hydrochloric acid so to catch the full about of gas given off and the.  § The temperature should be checked every 20 seconds over 200 seconds.  § To ensure for accurate results the test should be repeated multiple times the more times it's done the more accurate the results will be.  § Finally you should gradually change the molar from 0.25 to 2 (0.25, 0.5, 0.75, 1, 2) [IMAGE]

Total Housing Loan in Malaysia

Total housing loan in Malaysia have been increase from year to year. This is stated in the Bank Negara Malaysia (BNM) annual statistic report. Currently, there is an increase in the housing loan that have been approved by the bank from 2011 to 2012 . In order to own a house, there is a large amount of money is needed. House is a long term property and the price is high. Not every people are afforded to buy their own house if they have not completed certain requirements. Since house price is expensive, the availability of housing finance is very important. Nowadays, home financing has offer many kind of financial products to the homebuyers when purchasing their dream house. There are already various institutions which offer housing loans that prospective borrowers can access such as banks, state housing corporation/agencies or mortgage institutions. It has become very important that the financial institutions to determine the factors that are pertinent to the homebuyers in selecting a mortgage home loan provider as there are a rapid change and more sophisticated homebuyers on this day. In order to establish whether the homebuyers have the potential capacity to pay for their desired home, they were asked to estimate the average purchase price, the deposit required, and the deposit that they could afford as well as any saving that could be added to the funding package. Currently, Ministry of Housing and Local Government has introduced housing loan scheme or Skim Pinjaman Perumahan (SPP) which aim to help people with the low income to buy a house. The target group for this scheme are the households with the earning between RM500. 0 to RM1200. 00 per month and are not eligible for another loan to build a house or buy a completed low-cost house. Besides that, homebuyers have to consider in many dimensions such as down payment, maturity of the contract, repayment structure, the ability to refinance, the possibility of being subject to borrowing constraints, and the evolution of economic variables such as interest rate, inflation, house appreciation rate, unemployment rat e and income growth. Mortgage loan is one of the alternatives or source of finance in home purchases and it become the popular choice where property was used as the main sources of collateral secure the loan made. Today, there are more financial alternatives offered to the public and at the same time there are more options for Malaysian bank customers to choose from. In exploring the information would help service providers to identify appropriate marketing strategies needed to attract new borrowers. This study attempts to deepen about consumer decision making when selecting a service provider and what criteria are of most importance.

Heres How Schrodingers Cat Works

Erwin Schrodinger was one of the key figures in quantum physics, even before his famous Schrodingers Cat thought experiment. He had created the quantum wave function, which was now the defining equation of motion in the universe, but the problem is that it expressed all motion in the form of a series of probabilities—something which goes in direct violation to how most scientists of the day (and possibly even today) like to believe about how physical reality operates. Schrodinger himself was one such scientist and he came up with the concept of Schrodingers Cat to illustrate the issues with quantum physics. Lets consider the issues, then, and see how Schrodinger sought to illustrate them through analogy. Quantum Indeterminancy The quantum wave function portrays all physical quantities as a series of quantum states along with a probability of a system being in a given state. Consider a single radioactive atom with a half-life of one hour. According to the quantum physics wave function, after one hour the radioactive atom will be in a state where it is both decayed and not-decayed. Once a measurement of the atom is made, the wave function will collapse into one state, but until then, it will remain as a superposition of the two quantum states. This is a key aspect of the Copenhagen interpretation of quantum physics—its not just that the scientist doesnt know which state its in, but its rather that the physical reality is not determined until the act of measurement takes place. In some unknown way, the very act of observation is what solidifies the situation into one state or another. Until that observation takes place, the physical reality is split between all possibilities. On to the Cat Schrodinger extended this by proposing that a hypothetical cat be placed in a hypothetical box. In the box with the cat we would place a vial of poison gas, which would instantly kill the cat. The vial is hooked up to an apparatus which is wired into a Geiger counter, a device used to detect radiation. The aforementioned radioactive atom is placed near the Geiger counter and left there for exactly one hour. If the atom decays, then the Geiger counter will detect the radiation, break the vial, and kill the cat. If the atom does not decay, then the vial will be intact and the cat will be alive. After the one-hour period, the atom is in a state where it is both decayed and not-decayed. However, given how weve constructed the situation, this means that the vial is both broken and not-broken and, ultimately, according to the Copenhagen interpretation of quantum physics the cat is both dead and alive. Interpretations of Schrodingers Cat Stephen Hawking is famously quoted as saying When I hear about Schrodingers cat, I reach for my gun. This represents the thoughts of many physicists, because there are several aspects about the thought experiment that bring up issues. The biggest problem with the analogy is that quantum physics typically only operates on the microscopic scale of atoms and subatomic particles, not on the macroscopic scale of cats and poison vials. The Copenhagen interpretation states that the act of measuring something causes the quantum wave function to collapse. In this analogy, really, the act of measurement takes place by the Geiger counter. There are scores of interactions along the chain of events—it is impossible to isolate the cat or the separate portions of the system so that it is truly quantum mechanical in nature. By the time the cat itself enters the equation, the measurement has already been made ... a thousand times over, measurements have been made—by the atoms of the Geiger counter, the vial-breaking apparatus, the vial, the poison gas, and the cat itself. Even the atoms of the box are making measurements when you consider that if the cat falls over dead, it will come in contact with different atoms than if it paces anxiously around the box. Whether or not the scientist opens the box is irrelevant, the cat is either alive or dead, not a superposition of the two states. Still, in some strict views of the Copenhagen interpretation, it is actually an observation by a conscious entity which is required. This strict form of the interpretation is generally the minority view among physicists today, although there remains some intriguing argument that the collapse of the quantum wavefunctions may be linked to consciousness. (For a more thorough discussion of the role of consciousness in quantum physics, I suggest Quantum Enigma: Physics Encounters Consciousness by Bruce Rosenblum Fred Kuttner.) Still another interpretation is the Many Worlds Interpretation (MWI) of quantum physics, which proposes that the situation actually branches off into many worlds. In some of these worlds the cat will be dead upon opening the box, in others the cat will be alive. While fascinating to the public, and certainly to science fiction authors, the Many Worlds Interpretation is also a minority view among physicists, though there is no specific evidence for or against it.
