Get A Reaction Out Of This! A chemical reaction occurs when one or more substances change to produce one or more different substances. For example, some evidence that a chemical reaction has occurred is possible changes in energy, release of energy, formation of a new substance, or reduction or increase in temperature. This lab will be conducted in order to create a chemical reaction by changing the reaction rate of a substance. In order to change the reaction rate, a catalyst needs to be added
in that way Red remove Blue add Experimental section Chemicals: Ultrapure water with an electrical conductivity of 18.2 MΩ cm-1 produced from nano-filter (EMD Millipore Corporation, UK) was used for cleaning, making solutions, and doing electrochemical measurements. Cleaning solvents such as ethanol was purposed from Decon Laboratories (USA), acetone was purposed from Fisher Chemicals, USA, and isopropanol was purchased from Macron Fine Chemicals, USA. Chloroauric acid, hydrogen chloride, nitric acid
Introduction The purpose of this experiment was to test for quality control and analysis of a commercial product, in this case vinegar. The experiment performed determined the actual molarity of a specific brand of vinegar as compared to information provided on the bottle. The standardization of HCl and NaOH was also performed in order to understand the process of titrations. The importance of testing for quality control to be sure the product being sold holds up to its commercial value and is authentic
to be a Chemical Technician is so where I could use chemicals and discover new cures to help people. Why I like this job is because I would get to experiment every day and maybe discover cures for things that we don’t have cures for. I would also like to help as much as I could with Pharmacist’s and give them as much as I could to help people. The role that Chemical Technicians do is having the backbone to every chemical, semiconductor, and pharmaceutical manufacturing operation. Chemical Technicians
summary The given lab experiment had two parts within it.. The purpose of this assignment was to help student make better prediction, to observed chemical reactions, to designing the experiment, and to make a claim from the results of the experiment. The two activities that will be completed are Activity A: Sink or Swim , and Activity B: Dissolving Chemicals in Water. Claim The first Activity was to determine the bouncy between two objects. To determine with of the two would sink or swim ( float)
hairsprayed?” I will be testing the durability of hair with hair spray or without hair spray. For an experiment to be a scientific experiment (and research), it must have all the elements of the scientific method. The first requirement is to make observations. In this step it is required to gather general information by using senses. The second part is to state the question of the experiment. It must clearly state the independent and dependent variables, along with the actual question. It should
many different private companies for cosmetics and household products. The makers of the products choose animals to test their products on because many animals have similar organ systems and body processes that humans do. Scientists perform these experiments to better understand body processes and how a product will affect them. The process of experimenting on animals is completely inhumane and unnecessary because there are other When researchers perform any of these procedures wrong it causes the test
The purpose of this experiment was to make a conclusion on why Mr. R’s lawn was turning yellow, and dieing around his drainage pipe. In this experiment there were different lab groups that tested out different chemical products, that would be washed down a drain. There was a wide assortment of products that were tested in this experiment, for example, windex was one of the products being tested. On our experimental days, we would take our product, and add it to the water supply of our grass. My lab
Throughout history, animals have been used in experiments to test product safety and obtain medical knowledge that benefits both humans and animals alike. Every year there are numerous medical breakthroughs, such as medications and surgical instruments, which are tested on animals to insure their safety before they are deemed acceptable for human use. Even though the results of the experiments saved millions of human lives, they are also killing millions of innocent animal lives in the process
Every year in the UK alone 50-100 million mice, rats, fish, dogs, cats, non-human primates and countless other animals are test and experiment subjects. Introduced in the 19th century animal experimentation is a new concept in the history of science and medicine. Back then it was only a few basic experiments on animals or humans. As history progressed and humans began discovering more and more about the functions of human body curiosity increased. This led to American scientists testing out new types
million dogs, cats, and other animals are burned, poisoned and even killed in these tests each year. Can you imagine if you were doomed to live your entire life in a cage and constantly have aggravatingly painful experiments performed on you daily? But even worse, knowing these experiments would leave you with life-long injuries or even your death? This speech will include, firstly, what happens to animals in these tests, secondly, why animal testing should end and finally, what you can do to help
ethics of animal testing have always been questioned because humans do not want to think of animals on the same level as humans. Incapable of our thinking and unable to speak, animals do not deserve to be tested on by products and be conducted in experiments for our scientific improvement. Experimentation on animals is cruel, unfair, and does not have enough beneficial results to consider it essential. Humans and animals have many characteristics in common. Animal skin and organs are similar Primates
Over the course of history, the U.S government had conducted unethical experiments on unsuspecting citizens. There were medical experiments performed on poverty stricken people all for the name of science. Many of these experiments were done without people’s consent and left victims with severe physical and psychological damage. The victims were stripped away of their individuality and were given the titles of human guinea pigs, with no consideration for well-being. However, can medical science be
purpose for this procedure is for students to familiarize themselves with how different types of properties can lead up to identifying substances. For the safety of this experiment be sure to always have your goggles on and tightly secured, due to any splattering of chemicals or glass breakage. Under no circumstance should any chemical be near your mouth. In this procedure students will use four methods that will help identify what is their unknown substance. Once all methods are done its data will provide
several types of tests that are used on animals behind closed doors. The Draize eye test is a type of eye irritancy test that is mainly used on rabbits. They physically scream while toxic chemicals are poured into their eyes; which can lead to redness, bleeding, ulcers, blindness, and often death at the end of the experiment. Rats are typically injected with carcinogens that induce
free. Examples of animal tests include forcing them to inhale toxic fumes, force-feeding dogs pesticides, and rubbing chemicals into shaved or abraded skin. They endure these tests with
Laboratory experiments on animal Jack stumbled upon an article, about how animals are being abused, tortured and killed for the things we commonly use in our household. Written on the article is how a female dog, named Libby have gone through in the hands of researches, it says there that pharmaceutical companies have paid the laboratory to infect animals with worms, fleas, and ticks and smear toxin in their skin to test animal companion products, Imagine how animals are being treated in the confines
beaten, tortured, poked, and prodded to see how much pain they can endure and to see what experiments people can come up with will work. Scientists have used animals to test on for the creation of medicines and the chemicals that are put into those medicines; in addition, those medicines are used to find cures for diseases and to help out the human race. Companies have also used animals to test out experiments for the products they want to sell. Those companies need to see the effects that the product
pharmaceutical products on animals is highly dangerous” (HIV and AIDS Information and Resources). Many tests that are done on Animals and then released for the general use are; “Acute toxicity tests consisting of the administration of a single dose of a chemical at a concentration great enough to produce toxic effects and death. An example of such a test is the Lethal Dose 50 (LD50) test in which 50 per cent of the subjects in an experimental sample are expected to die. Biological screening tests designed
The Growth of Bean Seedlings Experiment Growth of a Beans Experiment Aim: To compare the growth of bean seedlings in a different soil solution. Background Knowledge: Plants make there own food by photosynthesis. They need light and CO2 from the atmosphere and the water absorbed from the soil. Plants also need very small quantities of minerals for healthy growth. Mineral ions are absorbed through the roots from the dissolved chemicals compounds in the soil. When garden centres sell
