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

These complementariness principles do not only underlie current ideas on the structure of the nucleic acids‚ but they form the foundation of all speculations‚ more or less well- founded‚ on their physical properties (denaturation‚ hypochromic- ity‚ etc.)‚ on the transfer of biological information from deoxy- ribonucleic acid to ribonucleic acid‚ and on the role of the latter in directing the synthesis of specific

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
