Vitamin C –A Natural Antioxidant Concept: Vitamin C (ascorbic acid) is an antioxidant. The amount of vitamin C content in food can be found out by titrating with an oxidising agent‚ e.g. iodine. In the reaction‚ vitamin C is oxidised‚ while iodine is reduced to iodide ions. The endpoint is determined by the formation of blue-black starch-iodine complex when all vitamin C is oxidised and excess iodine is free to react with the starch solution added as indicator. Introduction Vitamin C is an important

88‚ d = 11. (b) a = −29‚ d = 9 (c) a = 58237‚ d = 58168 (actual question is a = 58237‚ d = 58168 ) Solution: (a) Because 88 = 11・8 + 0‚ we have q = 8‚ r = 0. (The fact that r = 0 says that 11|88.) (b) Because −29 = 9・(−4) + 7‚ we have q = −4 and r = 7. (Note that although we can write −29 =9・(−3) + (−2)‚ we cannot use −2 as r because r is not allowed to be negative.) (c) a = d(q)+r 58237 = 58168(1) + 69 Quotient = 1‚ Remainder = 69 (c actual) We do not need to perform

The C programming language (often‚ just "C") is a general-purpose‚ procedural‚ imperative computer programming language developed in the early 1970s by Dennis Ritchie for use on the Unix operating system. It has since spread to many other operating systems‚ and is now one of the most widely used programming languages. C also has had a great influence on many other popular languages‚[1] especially [[C++]] which was originally designed as an enhancement to C. It is the most commonly used programming

Hepatitis C is a liver disease that is caused by hepatitis C virus. The virus enters into the liver cell‚ use the cell’s genetic to make copies of itself which then affects more cells. Causes Hepatitis C is usually transmitted through blood to blood contacts. It can be transmitted by sharing needles when injecting‚ toothbrushes and razors‚ tattoo or body piercing with equipment that has not been properly sterilized. It can also be sexually transmitted. It is not passed on by everyday contact

Differences: 1st point - Truman’s captivity was for the entertainment of millions if not billions of adoring fans. However Winston’s captivity was for political reasons. Similarities: 1st point - they were both being held against the will during at least one point in their story. 2nd point - they were both always being watched. They couldn’t do anything without everyone knowing about it. 3rd point - they both ended up at the end of the story ended up being left alone. Truman got to leave

Organic compounds are very important to a body. They are help the body to do things and replenish it. The 4 organic compounds I will talk about are carbohydrates‚ lipids‚ proteins and nucleic acids. I will explain what they do and what they are made of. Carbohydrates are in foods‚ some examples are sugars and starch. The structure of a carb is ring shaped‚ it is an easy one to know. The monomer of a carb is monosaccharide‚ which means one sugar. A monosaccharide consists of glucose‚ fructose and
