How do you neutralize sulferdioxide gas in power stations?
Sulfur dioxide gas in power stations can be neutralized by using a process called flue-gas desulfurization (FGD), which involves reacting the gas with an alkaline solution, commonly limestone slurry, to form calcium sulfite or sulfate. This reaction removes sulfur dioxide from the gas stream, reducing its harmful effects on the environment.
What dissolves limestone to form caves?
Carbonic acid, a weak acid found in rainwater, dissolves limestone over time to form caves through a process known as chemical weathering. As carbonic acid percolates through the limestone, it reacts with the calcium carbonate in the rock, gradually dissolving it and creating underground cavities that can develop into caves.
What is the name of the process when limestone loses oxygen?
The process where limestone loses oxygen is called calcination. This involves heating the limestone to high temperatures, causing it to release carbon dioxide and leaving behind calcium oxide, also known as quicklime.
Limestone chips dissolve after they are placed in a beaker of dilute acid. Which geologic process is this most similar to?
This process is most similar to the natural weathering of limestone rocks by carbonic acid in the environment, a type of chemical weathering. Over time, carbonic acid dissolves the calcium carbonate in limestone, resulting in the formation of features like caves, sinkholes, and limestone pavements.
Does acid rain attack limestone?
Yes, acid rain can chemically attack limestone by dissolving the calcium carbonate in the stone. This process, known as chemical weathering, can deteriorate the surface of limestone structures over time.
Why are most caves made from limestone?
Most caves are made from limestone because limestone is a sedimentary rock that is easily dissolved by water. Over time, acidic groundwater seeps into the cracks and crevices, dissolving and eroding the limestone to form cave systems. The process is known as karstification and is responsible for the creation of many limestone caves.
Which agent of reosion can create a limestone cave?
Chemical weathering - the rock is dissolved by rain-water acidified slightly by absorbed atmospheric carbon-dioxide.
What chemical weathering process would a marble rock undergo?
Dissolution by water, especially water acidified by atmospheric carbon dioxide (producing carbonic acid) or soil acids. Marble is composed primarily of the mineral calcium carbonate, modified to crystalline form by metamorphism of the parent limestone. Therefore karst features can develop in marble just as they can in unaltered limestone.
Foreign substance neutralized by antibodies in the immune process is called?
Antigen

What is lime stone caves?
Caves formed in limestone by its dissolution by ground-water weakly acidified vbyy absorbed atmospheric CO2.. This covers thevast majority of the world's caves, including huge systems like Mammoth / Flint Ridge (the world's longest)
What is a neutralized citizen of a country?
A neutralized citizen of a country refers to an individual who has undergone the process of naturalization, gaining citizenship in that nation, typically after fulfilling specific legal requirements. This process may involve residency, language proficiency, and knowledge of the country's culture and laws. The term "neutralized" may also imply that the individual has renounced their previous citizenship, thereby completely integrating into the new country.
What is the name of the process of acids and bases undoing each other?
Neutralization. Both the acid and base is Neutralized.
How does the carbon in limestone get back into the atmosphere?
Carbon from limestone returns to the atmosphere through the process of weathering. Rainwater and carbonic acid break down the limestone, releasing carbon dioxide into the air. This process is a natural part of the carbon cycle.
How do limestone caverns form?
Dissolution of the rock's primary ingredient, calcium carbonate, by water slightly acidified by absorbed atmospheric carbon-dioxide and percolating through the rock bulk's joints and other discontinuities. Eventually the network of initial tiny conduits will start to coalesce and capture, leading to discrete passages forming.
What happens when ethanol is oxidised with acidified kmno4 solution?
When ethanol is oxidized with acidified KMnO4 solution, it undergoes complete oxidation to form ethanoic acid (acetic acid). The purple KMnO4 solution is reduced to green Mn2+ ions in the process.
