The immense amounts of sulphur dioxide emitted into the air causes high levels of acid in the atmosphere. ... As with sulphur dioxide in rain, mercury is also discharged into the water. ... Acidic soil causes the carbon dioxide respiration process to decelerate. In order for plants to perform photosynthesis, they require carbon dioxide. ... The acid rain corrodes the thin, waxy layer, which coats and protects the leaves which in turn blocks the absorption of carbon dioxide and "suffocates" the leaves. ...

The EPA has confirmed that sulfur dioxide, carbon dioxide, and nitrogen are the major causes of these hazardous depositions. ... When these fuels are released into the air they are transformed into sulfur dioxide, carbon dioxide, and nitrogen. ... This blockage will prevent the leaf from pulling carbon from the air which is needed for trees to make food. Without carbon, trees cannot produce oxygen for animals to breathe in. ... He has not regulated the release of sulfur dioxide, one of the main causes of acid rain, and carbon dioxide as required by the Clean Air Act. ...

"By far the most common cause of acid rain is sulphur dioxide, which is believed to cause 70 percent of acid rain, with various oxides of Nitrogen (NOX) causing the remaining 30 percent"(4). ... This study explains that Congress had made amendments to the Clean Air Act in 1990, that was supposed to cut the sulfur dioxide and nitrogen oxide emissions in half in coal-fired power plants and other industries(2). ... By reacting sulfur dioxide with calcium oxide to form calcium sulfite is a way of preventing escape of sulfur dioxide form industrial operations. ... Calcium Carbonate can also react w...

The acidity of rain is determined by the pH of pure water in reaction with atmospheric concentrations of carbon dioxide, resulting in carbonic acid. ... A bicarbonate atom is an ion formed by one hydrogen atom, one carbon at atom, and three oxygen atoms, and is very effective in natural waters at neutralizing hydrogen ions and reducing acidity. ... Rain less than 5.7 is considered 'acid rain', meaning it has reacted with acidic atmospheric gases other than carbon dioxide, such as sulfur dioxide and nitrogen dioxide. ... These hydroxyl radicals are responsible for oxidizing sulfur dio...

Zyklon B is an insecticide and it released HCN, Hydrocyanic acid - a gas. It usually comes in small pellets or disks and the HCN is what causes the death. Zyklon B is extremely poisonous to humans and it's used in the execution chambers in the US. There were two types of chambers in Auschwitz - tho...

Unpolluted rainfall is slightly acidic, with a natural pH of about 5, due to naturally occurring constituents of the atmosphere, such as carbon dioxide, but acid rain has a pH of about 4. ... Since passage (1970) of the Clean Air Act, U.S. emissions of sulfur dioxide have been reduced substantially, due to the burning of low-sulfur oil and coal, installation of costly scrubbers in smokestacks (see smoke) and electric plants, use of pollution controls by metal processors, reduction of diesel-fuel sulfur contents, and the installation of catalytic converters to clean automobile exhausts. ...

Did you ever wonder why rocks dissolve over generations or why chalk disappears in certain liquids? Well so did I until I came up with an inventive experiment to figure it out. I wanted to figure out why an acid would react with a base. I had to think of a way to demonstrate this. However, this expe...

Review the effect of acid rain on the local distributions of fish and aquatic invertebrates. What are the biological reasons for the disappearance of these animals as pH falls? Humans produce about 160% of the natural emissions of sulphur. This is compared with about 5-10% in the case of carbon...
