What are the 3 elements that must be present in coal?
The three elements that must be present in coal are carbon, hydrogen, and oxygen. These elements make up the organic matter that was transformed and preserved through the process of coalification.
What element present in coal leads to acid rain?
Sulfur is the element present in coal that leads to acid rain when it combines with oxygen and water vapor in the atmosphere to form sulfuric acid. Burning coal releases sulfur dioxide into the air, which can then react with other compounds to create acid rain.
What elements are in coal?
it is a fossil fuel-the elements in coal are mainly hydrogen and carbon, with lower levels of hydrogen, oxygen, sulfur and nitrogen, yet some trace elements within coal are radioactive. These include Uranium, Thorium, Radon and Radium.
Which materials are absent when coal is formed?
When coal is formed, plant matter such as dead trees, leaves, and other vegetation is present. However, there is an absence of oxygen, intense pressure, and heat are crucial factors during the coal formation process.
What is the name of gas present in coal mine?
Methane is the gas present in coal mine.
The combustion of coal is a change?
The combustion of coal is a chemical change because it involves the chemical reaction of coal with oxygen to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. This process is irreversible and results in the formation of different substances than those initially present.
What element in the air is needed for coal dust to burn?
Oxygen is the element in the air that is needed for coal dust to burn. When coal dust is exposed to oxygen and heat, it can ignite and burn.
What is the equation for when coal reacts with oxygen?
The equation for when coal reacts with oxygen is: ( C + O_2 \rightarrow CO_2 ). This represents the combustion of coal where carbon in coal reacts with oxygen to form carbon dioxide.
What happens when coal is burn without oxygen?
When coal is burned without oxygen, it undergoes a process called pyrolysis where it decomposes into volatile gases, tar, and char. This can produce useful byproducts such as charcoal and coal gas, which can be used in various industrial processes.
Is oxygen present in fossil fuel?
Yes, fossil fuels like coal, oil, and natural gas were formed from organic matter that once contained oxygen. However, as the organic matter decays and undergoes heat and pressure over millions of years, much of the oxygen is removed, leaving behind mostly carbon and hydrogen.
Why is coal only found in certain places on earth?
Coal is formed from the decayed remains of plants in swampy areas with high vegetation growth. The presence of these specific conditions, such as a lack of oxygen and pressure, is necessary for the formation of coal. Therefore, coal deposits are only found in regions where these conditions were present millions of years ago.
What can clean coal power?
oxygen
