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

Flowers and Acid Call them freaks‚ the underground‚ the counterculture‚ flower children‚ or just simply hippies‚ they are all loose labels for the youth culture of the 60’s that transformed life in the West as we knew it‚ introducing the spirit of freedom‚ of hope‚ of happiness‚ of change‚ and of revolution (Miles 9). The years that made up the 1960’s were some of the most exciting and turbulent years in American history. The post World War II baby boomers grew up. A president and

A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are proton (H+) donors. They are the most common type of organic acid. Among

structures and properties of amino acids know the groups of amino acid What are amino acids? Amino acids are molecules that when combined with each other proteins. Amino acids contain a central tetrahedral carbon atom (α-carbon) amine group‚ carboxyl group‚ R-side chain The R-side chain determines the different amino acids There are 20 common amino acids Amino acids can join via peptide bonds Several amino acids occur only rarely in proteins Some amino acids are not found in proteins 3D

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor. Any

Nitric acid is a highly reactive oxidizing agent used in making fertilizers‚ explosives‚ and rocket fuels‚ and in a wide variety of industrial metallurgical processes. It is also a component of acid rain. Its chemical formula is HNO3 and it has been known as “aqua fortis”‚ which means strong water‚ to alchemists. It is a transparent‚ colorless to yellowish‚ fuming corrosive liquid. Nitric acid is a strong acid and therefore it completely dissociates in water. It has a gravity of 1.41 and the concentration

Cause and Effect on Acid Rain Introduction Beautifully crafted statues are now worn out or severely damaged‚ aquatic wildlife population are dying off‚ forests have lost the leaves that protect their trees and produce food‚ and the rates of lung diseases in humans are rising around the world. The cause of all of these problems can be linked back to acid rain. Most people don’t understand the concept or science behind acid rain. The common belief is that it’s a natural process‚ but it’s actually
