agency NASA selected Gram Power’s technology among the top-10 cleantech innovations from around the world. Two fresh graduates from the University of California Yashraj Khaitan and Jacob Dickinson founded GRAM POWER which enables villagers to generate and store renewable energy from biomass‚ solar or wind on-site. While on a university project they came to know about the scarcity of electricity in villages‚ this goaded them to devise energy solutions for villagers. This year‚ Gram Power set up India’s

Chemistry Research Paper What is an anti acid? According to Cindy Quarters (2010)‚ “Antacids are medicines that are taken orally to help relieve sour stomach‚ heartburn‚ or acid indigestion”. This medicine is available without prescription but it is needed to take the correct dose. The different types of anti acids include calcium carbonate‚ sodium bicarbonate‚ magnesium hydroxide‚ aluminum hydroxide‚ and dihydroxyaluminum sodium carbonate. The cost of the anti acid will depend on how effective

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

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

EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled

chemical reaction. In chemistry we describe concentration in terms of the number of moles of a substance there are in every cubic decimetre (litre) of solution‚ written as moles.dm-3 of M for short. • In this experiment you will find out how increasing the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium metal. • As the metal reacts with the acid‚ hydrogen gas is produced and the metal dissolves. To get an estimate of the rate

Small samples of acetaminophen‚ acetylsalicylic acid‚ cellulose‚ starch‚ and caffeine were obtained. These samples were then placed into seperate sets of test tubes that contained water‚ acetone‚ or dichloroethane. Solubilities were then tested for each sample in each solution which can be seen in Table 5. Next‚ four random pills were obtained and weights were taken of each. Each of the pills were grinded up using a separate mortar and pestle. The grinded up pills were then weighed. The grinded

Acid Strength Grade 10- Science (chemistry) 11/23/2012 Mariana Boff Acids Strength Acids are substances that contain hydrogen atoms which detach to form hydrogen ions when the acid is dissolved. Acids are divided into two main categories: the strong and weak acids. The stronger ones are very corrosive and can cause severe skin burns‚ here are some examples: nitric acid (HNO3)‚ hydrochloric acid (HCl) and sulfuric acid (H2SO4). The weaker ones are less corrosive and when in touch with the
