factors. Many believe that it is hard work that bring them success‚ others think that luck is more important. I totally agree with the quotation‚ because I believe that success comes from hard work‚ as Newton said “Genius is one percent inspiration and ninety nine percent perspiration”. People often believe that luck is something that is beyond our control. How can we know when we get a big contract? How can we predict when our experiment give way for a new discovery? I disagree with this kind

Formic acid is known to be the simplest carboxylic acid‚ and it is an important factor in chemical synthesis and occurs naturally. The chemical formula for Formic Acid is CH202‚ and is mostly found in the venom of bee and ant stings. Formic acid is clear and colorless with a pungent odor. Formic acid is used in many ways; Formic acid is used to preserve livestock. It is also sprayed on animal food and fresh hay to reduce the decay rate. It can also be used as a pesticide to protect bee

Baking Soda and Vinegar Rocket All the materials you will need are very simple house hold; scissors‚ balloon‚ vinegar‚ baking soda‚ rubber band‚ empty bottle‚ clear wrap‚ straight pin‚ marker‚ thin piece of wood‚ drinking straws‚ and duct tape. One of the first steps is to make the rocket fuel the key component in this rocket. I began with placing ¼ or 1/3 of vinegar in a normal size bottle‚ after that you will make the baking soda bomb. You take a piece of clear wrap and place a good amount of

Acid Property #1: The word acid comes from the Latin word acere‚ which means "sour." All acids taste sour. Well known from ancient times were vinegar‚ sour milk and lemon juice. Aspirin (scientific name: acetylsalicylic acid) tastes sour if you don’t swallow it fast enough. Other languages derive their word for acid from the meaning of sour. So‚ in France‚ we have acide. In Germany‚ we have säure from saure and in Russia‚ kislota from kisly. Base Property #1: The word "base" has a more complex

In Defending the One Percent‚ Gregory Mankiw begins with difficult to imagine experiment where a perfect economic equality exist and one day the utopia is disturbed by a genius entrepreneur with an idea of a new product. Because of the magnificent idea everyone would like to buy the product in a voluntary exchange‚ which results in an extreme unequal distribution of income. Since there are no policies that follow the Pareto criterion‚ the question is if the government should shift to a progressive

Reduction Titrations: The Indirect Iodimetric Analysis Ascorbic Acid Unknown Number 69 I: Purpose: To determine the percent weight of Ascorbic Acid in unknown sample. This was to be done by the means of an indirect iodimetric analysis. In an iodometric analysis‚ the oxidizing agent can be determined by a different means than titrating directly with standard iodide‚ because a high concentration of I- is needed to form the I3- complex. In this type of analysis‚ excess iodide is added to the oxidizing

Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore
