Acid rain is considered precipitation in the form of rain‚ snow‚ or fog. It is not regular precipitation. It is precipitation that is polluted by acid. Emissions of sulfur dioxide and nitrogen oxide into the atmosphere cause this precipitation to become acidic. These emissions are released into the atmosphere by human activity‚ such as automobiles‚ industries‚ and electrical power plants that burn fossil fuels like coal and oil. When these gases are released‚ they mix with water vapor in the clouds

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

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 of reaction‚ the time taken for a small piece of magnesium ribbon to dissolve (disappear) can be measured. This is a “clock reaction” and the reaction rate is proportional to 1/time taken SAFETY Dilute hydrochloric acid is harmful. Wear safety spectacles

Suggested time allotment: 5 to 6 hours MODULE 2 ACIDS AND BASES In Module 1‚ you identified common properties of solutions using different methods. You learned how to report the amount of the components in a given volume of solution. You also found out that not all solutions are liquid. Some of them are solids and others are gases. Towards the end of the module‚ you investigated the factors that affect how fast a solid dissolves in water. Most of the solutions you studied in Module 1

Jennifer Everett Phase 4 DB Instructor: Clement Yedjou 3/10/2015 Acid rain Acid rain is a result of air pollution that is harmful to the environment‚ generally caused by fuels being burnt. When any type of fuel is burnt‚ many different chemicals are produced. These gases that are released react with the water in clouds‚ and the rain from these clouds is acid rain. This type of acid disposition can appear in many other forms besides just rain‚ such as sleet‚ snow‚ and fog (Editorial Board‚ 2013)

GIVEN: TO DESIGN A 1000TPD CAPACITY H2SO4 ACID PLANT BASIS: 1 HOUR OF OPERATION. PURITY: PRODUCT WHICH IS TO BE MANUFACTURED IS ASSUMED TO HAVE STRENGTH OF 98% ACID. 1000TPD implies that we have Acid 1000 x 10 / 24 = 41666.67 Kg/Hr of 3 With 98% purity‚ the acid that is produced per hour = (98 x 41666.67) / 100 = 40833.34 Kg/Hr Kmoles of Sulfuric acid to be produced = 40833.34 / 98 = 416.667 Kmoles/Hr It’s assumed that overall absorption of the acid is 100 % = 416.667 / 1.0 Then‚ SO3 required

Acid Rain and the Effects of our Monuments and Churches The two controlled experiments that I chose to do‚ do not involve trees or plants‚ which I think a lot of people will be doing. I wanted to explore the devastation that acid rain does to our historic monuments and beautiful churches. My first controlled experiment is based on the Statue of Liberty. It is made of copper so I am using pennies in my experiment. (nps.gov. n.d.) My observation is that acid rain corrodes metals

Introduction: Acid rain has proven to be a big problem for Connecticut. It has had a great impact on builders‚ wildlife‚ and the water sources. Acid rain has many components in it such as pollutants from plants to sulfuric acid from burning coal. Problem: Which stone is the most resistant against acid rain? Hypothesis: If we test the different stones against acid rain then red sand stone would be the best because it is heavier and cannot be easily broken. Independent variable: Type of stones

of Muscle Proteins to Infer Evolutionary Relationships of Mammals‚ Fish and Birds Abstract This experiment used electrophoresis to examine the makeup of muscle proteins from two mammals (cow‚ Bos taurus; bear‚ Ursus americanus)‚ two aves (chicken‚ Gallus gallus; turkey‚ Meleagris gallopavo)‚ and two fish (King Salmon‚ Oncorhynchus tshawytscha; Albacore Tuna‚ Scombridae unclassified). The hypothesis was that as species have diverged evolutionarily‚ the makeup of their muscle proteins has also

After calculating‚ this meal came to 225 grams of carbohydrates. It was enough to keep my blood sugars regulated without feeling overly stuffed. For lunch‚ if I am being completely honest‚ I did not take my blood sugars. I figured since I was feeling fine and well‚ I was hungry that I would be okay skipping one reading and/or dose of insulin. I prepared myself another 75 gram carbohydrate meal that included one turkey sandwich with mustard‚ one cup of my leftover chili
