AND OIL DEFINITION: Fats and oils‚ group of organic substances that form an important part of the diet and also are useful in many industries. The fats are usually solid‚ the oils generally liquid at ordinary room temperatures. Some tropical products‚ liquids in their sites of origin‚ become solids in cooler climates; in commerce these often retain the name originally given‚ e.g.‚ palm oil and coconut oil. Chemically fats and oils are either simple or mixed glyceryl esters of organic acids belonging

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

Manufacturing of Sunflower Oil Refined sunflower oil will be ready to consume after two manufacturing processes. They are raw oil manufacturing and refining processes. These two steps are charted below. Chart-I: Manufacturing of Raw Oil Chart-II: Manufacturing of Refined Oil Raw oil manufacturing consists of 2 stages. These are pressing and extraction stages. In the first stage‚ seed of sunflower becomes sunflower oil. Cleaning‚ breaking‚ separation‚ shimming‚ roasting and pressing processes

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

coconut oil due to its high levels of saturated fat. Advocacy against coconut and palm oils in the 1970s and 80s due to their perceived danger as a saturated fat caused companies to instead substitute trans fats‚ unaware of their health-damaging effects.[28] Coconut oil contains a large proportion of lauric acid‚ a saturated fat that raises blood cholesterol levels by increasing the amount of high-density lipoprotein (HDL) cholesterol[29] that is also found in significant amounts in laurel oil‚ palm

Lorenzo’s Oil Essay The film is based on the true story of Augusto and Michaela Odone and their son Lorenzo. In 1984 Lorenzo came down with adrenoleukodystrophy (ALD)‚ a rare inherited disease. Doctors said that he would lose all his functions and die within two to three years. Refusing to accept this grim verdict‚ the Odones set out on a mission to find a treatment for ALD and to save their child. In their quest for a treatment the Odones often clashed with doctors‚ scientists‚ and support groups

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
