Sulfur trioxide

Sulfanilamide, also referred to as sulfa, was a drug sold in powder and tablet form used to treat infections such as pneumonia, meningitis, and strep throat. In the 20th century, these bacterial infections could easily take the life of anyone. That is why sulfanilamide became so popular throughout the country. Sulfanilamide was invented by a German microbiologist, Gerhard Domagk. It was a red dye derivative that he had discovered that would cure the contagion. The drug was safe until a salesman from

Does the amount of surface area of a roughly 1 millimetre thick piece of magnesium metal in equiangular quadrilateral cuboid or ”strip” form and of mass close enough to assure a relatively low measure of standard deviation when compared with other specimens from the pre-determined collection of magnesium metal it came from proportionally affect the magnitude of the rate of its reactions when surrounded by a solution of hydrochloric acid? I believe that yes, the amount of surface area of a piece

Mercury: The element mercury has the chemical symbol Hg; it is a silver colour and is a liquid at room temperature. Mercury has a high density and surface tension and can easily break up into small droplets. Mercury can dissolve some metals resulting in amalgams, metal alloys of mercury. It is not soluble in water or most other liquids, but will dissolve in lipids (fats and oils). With fluctuations in temperature, mercury expands and contracts evenly with these changes and is classed as a non-combustible

carbon, nitrogen and sulfur that can harm our environment greatly. These oxides can be produced naturally and industrially. Sulfur dioxide is produced when organic matter decomposes and forms hydrogen sulphide which then oxidises to the oxide: 2H2S (g) + 3O2 (g) 2SO2 (g) + 2H2O. The natural sources of sulfur dioxide are in volcanic gases, bushfires, sulfur rich geothermal hot springs releasing gases and the decomposition of organic matter. The industrial sources of sulfur dioxide such as in processing

Acid Rain's Effects on the Environment Acid rain causes damage to limestone bulidings. Scientists are concerned that increased air pollution may cause an increase in the concentration of acid in the rain. If this is the case then it would increase the damage done to limestone bulidings. Acid rain is caused when we burn fuels. When we burn these fuels we make a gas called sulphur dioxide. This gas goes into the air. The sulphur dioxide reacts with the oxygen and then

made acidic by Sulfur DiOxide ( SO2 ) and other pollutants. Acid rain is formed by the release of ( SO2 ) and ( NO2 ) into the atmosphere. Then the chemicals are absorbed into the rainwater and create acid rain. Acid rain , mostly comes from the chemicals emitted into the air by coal fired power plants. Now there is a big push for clean coal and these power plants have mostly accomplished that. The power plants have scrubbers, covered in limestone that remove or “ scrub” the sulfur oxide, nitrogen

Acid Rain Acid Rain is a common term to describe how acid falls from the atmosphere onto the earth. The real term is acid deposition; this term refers to acidic rain, fog, and snow. Acid Rain occurs when the two gases sulfur dioxide (SO2) and nitrogen oxides (NOx) react with each other in the atmosphere with water, oxygen, and more chemicals to form many acidic compounds. Scientists measure acid rain by using a scale called a pH scale. What they do is measure the normal rain. Normal rain is slightly

INTRODUCTION: The dictionary definition of acid rain is “’rainfall made so acidic by atmospheric pollution that it causes environmental harm, chiefly to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulphur and nitrogen oxides which combine with atmospheric water to form acids.” In Northern Europe and North America millions of trees have died because of the causes of acid rain. Some lakes contain so much acid that all

The world we live in today has become a nest for pollution, toxic waste and environmental deterioration. In order to improve our planet, acid rain is a main factor to be considered and must be controlled before the damage worsens. In order to understand what acid rain is, we must first understand the term “acidity”. Acidic is a way to describe chemical compounds and it is measured on the pH scale, a logarithmic measure of the concentration of hydrogen ions (H+) in precipitation (1). This scale

droplets that are unusually acidic because of atmospheric pollution, most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Acid deposition can be causes by natural sources like volcanoes, but it is mainly caused by the release of sulfur dioxide and nitrogen oxide during fossil fuel combustion. When these gases are discharged into the atmosphere
