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

Among the most harmful and dangerous non-metal compunds are nitrogen oxides‚ sulphur dioxide‚ carbon dioxide‚ carbon monoxide‚ and hydrogen sulphide. These can cause devastating effects to human beings‚ plants‚ animals and the environment. Matals are generaly less harmful‚ although lead is extremely toxic. Hydrogen sulphide is a highly toxic gas. It has a very bad smell‚ often identified in rotten eggs and stink bombs. Hydrogen sulphide interferes with cellular respiration. If inhaled‚ Hydrogen

Introduction : Copper(II) sulphate‚ is a type of salt which it is formed by combining both copper ion and sulphate ion through the experiment of double displacement between dilute sulphuric acid ‚ and copper(II) carbonate ‚ . Through this process‚ the copper ion will displace the hydrogen ion as it is more electropositive and sulphate ion will displace carbonate ion as it is more electronegative. The resulting copper (II) sulphate solution when cooled can easily crystalize

Act recognizes sulfur as a contributor to the acid rain problem and enacted a goal to reduce total national sulfur dioxide emissions to half of 1990 levels. The Act describes the cap and trade approach whereby companies are permitted to pollute a certain amount of sulfur dioxide compared to levels of electricity output they produce. Rainwater is naturally acidic with a pH of around 5.7. Acid rain can be defined by anthropogenic acidification caused by nitrogen compounds and sulfur dioxide‚ formed

Harvard Business School 9-792-060 Rev. April 28‚ 1993 Acid Rain: The Southern Company (A) Early in 1992‚ managers at the Southern Company were reexamining their strategy for complying with the acid rain provisions of the 1990 amendments to the Clean Air Act. The Southern Company was a holding company; its operating units were electric utilities in Georgia‚ Alabama‚ Mississippi‚ and Florida. The largest Southern subsidiaries‚ Georgia Power and Alabama Power‚ provided most of the electricity

1.) Explain why the following substances are added to soil by gardeners and farmers. a.) Lime CaO It increases the pH of soil.Soil that is too acidic presents two different problems for crops. First‚ the amount of necessary minerals in the soil such as potassium and calcium decreases. Second‚ aluminum and manganese levels increase to potentially toxic levels below a pH of roughly 5.5.Calcium oxide‚ addresses the problem. It reacts in water to release calcium ions and hydroxide ions‚ which raise

it is made of. Both sulfur dioxide and sulfur trioxide are chemicals that are called acidic oxides. They react with water to form their corresponding acids- sulfurous acid and sulfuric acid. The increasing concentration of these molecules in the atmosphere in recent years has caused the environmental problem we know as acid rain. There are a number of sources of sulfur dioxide. A natural source is volcanic eruptions. Many metals in nature are in a combined form with sulfur. When smelting or roasting

Research 1. Assess evidence‚ which indicates increases in atmospheric concentration of oxides of sulfur and nitrogen. Thorough collection of data‚ surveys‚ and tests from the 1950’s indicate a rising trend in atmospheric concentrations of oxides of sulfur and nitrogen. An enhancement in funding‚ technological and information resources‚ has led to wider and more detailed analyses of oxides of sulfur and nitrogen concentrations‚ and as the diagrams indicate (see diagrams) there is a clear rise in
