Sulfur dioxide

The specter of nuclear, biological, chemical (NBC) attack or accident has loomed over our society for generations. Of the family of chemical agents, is the class of vesicants – also known as Blister Agents. Though there are different types of blister agents, their mechanism of action against their victims are the same. A wide spectrum of protective equipment and detection devices are commercially available for first responders in contending with a blister agent incident. Weaponized blister agent…

(s) + H2. This is a single replacement reaction. This reaction most commonly occurs through contact with hydrogen sulfide in the air - although direct contact with substances that contain sulfur can cause tarnishing. Silver tarnishes very quickly when it is exposed to air that contains high levels of ozone, sulfur, or hydrogen sulfide. Silver tarnish appears as a discoloring over the surface of the metal. Rather than the usual shiny or soft appearance of silver, the item’s color could range…

ABSTRACT: Acid mine drainage has a prominent and damaging effect on the environment. This paper outlines the environmental impact, the chemistry behind the acid generation, and methods of treatment. The objective of this paper is to educate the reader about acid mine drainage, and what can be done to reduce this pollutant. INTRODUCTION/BACKGROUND: Acid mine drainage (AMD) often occurs at abandoned mining sites. Acid generation is the result of combining certain minerals, water, and an oxidant.…

Equilibrium Paper There are multiple ingredients used to make baked goods rise; baking powder and baking soda are among them. The difference between single and double-acting baking powders is simple. Single-acting releases the carbon dioxide bubbles when mixed with a liquid ingredient and double-acting soda releases bubbles when the baked item is placed in heat. Baking soda and baking powder are remarkably similar, yet there are distinct differences. One is that baking soda is a strong base,…

Coal power plants are one of the top polluting sources of carbon dioxide in the world, just behind vehicle emissions. The article ‘Coal power: pollution, politics, and profits’ states that the “Negative health effects on the nearby human population, plant life, and wildlife have been hard to quantify precisely and thoroughly, and are generally not included in the cost of coal power to the consumer” (Laskowski). Due to this, the general population is not aware of how destructive this power source…

2016). Therefore, more nitrogen in the air is reacting with the oxygen, producing nitrogen dioxide, which then dissolves in rainwater, producing nitric acid. Nitric acid is one of the main mineral acids that contribute to…

However, it also brings some unwanted side effects, such as air pollution and water pollution. In order to develop industries, the consumption of fossil fuels increases. Burning of fossil fuels emits lots of air pollutants, such as sulfur dioxide, nitrogen dioxide, carbon dioxide, and other particles. Private cars and other vehicles also discharge a large amount of air pollutants. Increasing air pollutants in the atmosphere make it difficult to breathe and cause many other problems in China,…

What is acid rain? Acid rain is a form of deposition in which chemicals with an acidic pH level are taken out of the atmosphere through precipitation. When we pollute the air by burning fossil fuels, we create different chemicals that end up in our atmosphere. A few of these have chemical reactions with the water in clouds, and form (depending on the chemical) sulfurous and nitrous acids. When it rains, this acid is taken back to the ground. While pure water has a neutral pH level of 7,…

introduction, transitions to Dante’s Peak, which is a Composite volcano (Stratovolcano). Dante’s Peak starts indicating signs that an eruption is coming; different types of earthquakes, volcanic activity in the hot springs, carbon dioxide (CO2) levels in the air, sulfur dioxide (SO2) in the water supply and acidic lake levels. From here, the movie does a really great job of illustrating…

Sulfur dioxide promotes heart disease and asthma. Coal-burning plants are industrial polluters States producing about one-third of our carbon dioxide (CO2, a major contributor to GLOBAL WARMING), 40% of our mercury (highly TOXIC if ingested), one-quarter of our nitrogen oxide (found in smog) and two-thirds of our sulfur dioxide (a part of acid rain). But yeah, let’s all continue using this source of energy because…
