Advantages: Sulfamic acid is the fastest de-scaler - It dissociates into hydroxonium ions more readily in aqueous solution than the others‚ therefore giving a greater concentration of atoms that are able to react with the calcium in lime scale. It is safe to use because it does not produce chlorine gas [5]‚ which can be toxic. Sulfamic acid also has a low volatility. Disadvantages: Sulfamic Acid can be an irritant to eyes or skin and is the most expensive of the de-scalers. Q2) How these de-scalers

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

more acidic by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚

What is AIDS? Human immunodeficiency virus (HIV) is a lentivirus (slowly-replicating retrovirus) that causes acquired immunodeficiency syndrome (AIDS)‚ a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive (1). A virus is a piece of genetic material‚ RNA or DNA‚ surrounded by a protein coat. To replicate‚ a virus must infect a cell and direct its cellular machinery to produce new viruses. A virus cannot

Separation of Amino Acids by Paper Chromatography Chromatography is a common technique for separating chemical substances. The prefix “chroma‚” which suggests “color‚” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment‚ chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate and identify amino acids‚ the building blocks of proteins

United by Similarities‚ Separated by Differences “Man has been studied more carefully than any other organic being‚ and yet there is the greatest possible diversity among capable judges whether he should be classed as a single species or race‚ or as two‚ as three...or as sixty-three” (Darwin‚ 83). In The Descent of Man Darwin argues whether humans are one species or if the races of the world make up their own respective species. Darwin considers both the differences and similarities between races
