* What is this substance This substance is iodide Confidence Report The aim of extraction, is to separate a part of raw material, using a solvent such as water with heat. A tincture of iodine is a common medicine sold in many pharmacies, used as an antiseptic on cuts of the skin. The objective of the seaweed lab, is to produce a tincture of iodine by extracting Iodide and other components (seen when a mixture of iodine is present), from seaweed. We
Many companies selling these products make claims, for example, that creatine monohydrate is poorly absorbed and or poorly metabolized by the body. This is simply untrue: research has found that creatine monohydrate is highly absorbable. Some claim less “bloating” or other supposed effects of monohydrate, but don’t have a drop of data to support the claim, or even a feasible theory as to why their form would not have the effect vs. the monohydrate form. They often claim dramatically improved absorption over monohydrate (without data), fewer side effects (without data), the ability to reduce the number of non-responders to creatine (without data), etc. Are you starting to see a theme here?!
You can discuss the effects UV radiation has on the skin, including its affects as exposure increases. Discuss the potential problems that can occur from tanning, including developing cancer. You can also compare and contrast outdoor and indoor tanning; many people think using UV tanning beds is safer than the "old fashioned" way of tanning...but is that true? The Nature of Beauty Discuss how the ideas of beauty have evolved or devolved over the years. This is more of a history paper, but it's still perfect for cosmetology because it will make your audience see how beauty and cosmetology have changed over the years.
Our result would have been clearer to observe if we centrifuged it long enough because we might have lost some of the precipitate while washing it since it was not centrifuged long enough. 4. Answer the post lab questions: a. Zn + I2 + H2O Zn(OH)2 + I2 b. Zn(OH)2 + CH3COOH Zn(O2CCH3)2 c. A side reaction is an unwanted chemical reaction taking place that diminishes the yield of the desired product. d. In the synthesis of Zinc iodide, acetic acid was used because the aim of the experiment was to derive Zinc iodide. If we used water instead of acetic acid then zinc would have reacted with water and become Zinc hydroxide which would hinder our purpose.
The purpose of washing the test tubes thoroughly is so the chemicals don’t cross contaminate and affect the outcome of another section of the lab. Hypothesis: 1. If a substance contains lipids then when rubbed onto a paper bag a transparent or opaque spot will appear. 2. Is a substance contains starches then when iodine solution is added to the substance it will change from yellow-brown to blue-black.
58 Generally, dietary supplements are ingested orally and lack abuse potential. 59 Despite the reduced level of regulatory scrutiny and quality assurance, public interest in botanically derived treatments continues to rise. Acknowledging such interest, and the fact that technology has improved significantly in recent decades, the FDA issued a 2004 guidance document that sets forth the principles to which pharmaceutical manufacturers must adhere when developing prescription medications derived from complex botanical material. 60 The Guidance permits some leniency in the biochemical characterization of a prospective botanical agent the early stages of research; however, at
While the non-standard is just what is made in a lab well that is at least what I once thought. Though through the studies of this class I have come to find out different I found the truth. Standardized herbs or extract is the main component of an herb that gives it’s healing property and then is enhanced to make it more potent. While this is great and all it does delivery a stronger dose faster than a non-standardized herb. There is also the possibility that by choosing standard over non-standard your might be missing out on another factor that make the herbs main component work even better.
Kent Williams Current Economics Research paper 20 March 2010 Deviance of Steroids Have you ever looked in the mirror and wanted to look a little bit more ripped or toned? Maybe you just don’t have the talent in a certain sport and want to get better. These are just a few of thousands of reasons why people would take steroids. There are millions of supplements in today’s world that are supposed to help people gain strength, get bigger, strong, faster and even look better. Most of these supplements are legal while a few are not.
The purpose of this brief is to provide scientific evidence of the health risks and benefits regarding regulating tanning beds. Tanning is the process in which the skin pigmentation deep from exposure to ultraviolet (UV) radiation (Oxford dictionary, 2010). Tanning usually indicates skin damage resulting from either natural sun light or artificial tanning. Both sources supply UV radiation and it is a mixture of invisible electromagnetic radiation. ultraviolet A, ultraviolet B, and ultraviolet C are the three types of radiation.UVC is filtered by the atmosphere, UVB causes damaging suborns and UVA is responsible for skin aging.
For example, Pollan talks about margarine, and how scientists “claim” that it is a better, and cheaper substitute for butter, but it contains all these unnecessary ingredients that could be more harmful to the human body. Scientist believed by taking out saturated fats and cholesterol they could make margarine healthier, but what they did not know was it would produce unhealthier fats known as, trans fats. People never think about how deep and revealing food can be, but after reading this novel it’ll open your eyes to what really lies
