Magnesium hydroxide

basic compound donates a hydroxide anion which collectively form a product containing salt and water. The dissociation of the acid and base allows for the formation of the salt and water. Similarly, antacids are formulated to neutralize the hydrochloric acid present in the human…

Manganese dioxide (MnO2) 2. If the temperature of a reaction is decreased, what effect will this have on the rate of reaction? A. It will have no effect. B. The reaction will stop. C. The rate of reaction will increase. D. The rate of reaction will decrease. 3. Given the equilibrium reaction in a closed…

charged with 18.4 mL of concentrated ammonium hydroxide. While on ice and with the stir bar mixing vigorously, 1.88g of 10-(camphorsulfonyl)chloride in 18.4 mL of methylene chloride was slowly over 20 minutes. This mixture was allowed to stir and react for 1.5 hours at 0° Celsius. The phases were then separated. The aqueous phase was washed with methylene chloride twice with 15 mL of methylene chloride. The organic extracts were combined and dried with magnesium sulfate and the solvent was…

Noor Diabi 11AA The life of hydrochloric acid in our stomach Chapter 14 section 1 25/04/2016 Ms. Sara Kassem Sharjah American International School Topic one: Discuss the role of hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produced.  Hydrochloric acid (HCl) is a clear, liquid. Which is produced in…

1. Which impurity particles are larger, the one causing the water to be cloudy or the one causing the water to smell? Explain. The common problems with water are colors, smells and tastes. First, there are several problems of colors. Brown, red, orange, or yellow water is usually caused by rust. The different colors can be attributed to varying chemical oxidation states of the iron (rust) and by varying concentrations of the rust in the water. Moreover, blue or green color is generally a result…

Introduction The contamination of large bodies of water is becoming a greater problem across the world due to our rapidly increasing population. People commonly pollute these areas with their release of waste products and trash, and these contaminants can spread from small streams or lakes to oceans and complete ecosystems. The pollutants that are released into the water sources are often inorganic substances, and the dissolved forms of these compounds can become ionic cations and anions. An…

because water molecule carried partial positive charge on hydrogen atom and partial negative charge on oxygen atom; they could react with cation and anion from salts that have ionic bonds (Reece, etc. 2011). Therefore, salts such as sodium chloride magnesium sulfate would fully dissolve. Our data indicated that sodium chloride was not fully dissolved (Table 1), which it was not expected. That could be caused from adding too much salts into a little bit amount of water. Water…

Discussion of the Results and the Scientific Explanation The purpose of this experiment was to identify an unknown compound and discover its properties by devising experimental designs that enable for its identification (Cooper, 2009). Fifteen possible compounds were given, and a series of qualitative tests were used to eliminate the different possibilities and identify the specific unknown compound. These tests included a solubility test, which determines whether the compound is soluble in…

surgery, “The primary endpoint was met by 5% of patients in the medical therapy group, as compared with 38% of those in the gastric bypass group and 24% of those in the sleeve gastrectomy group” (Yafi, M. 2014). 2. Medication schedule: Magnesium hydroxide/aluminum hydroxide (Mylanta) 15 mL PO will be scheduled at 06:00 AM, 11:00 AM, 05:00, and 09:00 PM, Ranitidine (Zantac) 300 mg PO at 09:00 PM, 60 minutes before meals, while Sucralfate / Carafate 1 g or 10ml suspension (500mg / 5mL) will be…

Before the invention of modern antacids, people would chew chalk (calcium carbonate) to relieve the burning felt by too much acid in the stomach. But most currently used antacids are a combination of aluminum and magnesium hydroxide, often containing sodium bicarbonate as well. The antacids counteract stomach acid by neutralizing the acid, because antacids are formed of bases. Stomach acid, or gastric acid, is made of hydrochloric acid, potassium chloride, and sodium chloride…
