How does coal weather or erode?
Coal can weather and erode through physical and chemical processes. Physical weathering occurs when coal is exposed to temperature changes, leading to cracking and fragmentation. Chemical weathering happens when coal reacts with moisture and oxygen, resulting in the breakdown of its organic compounds. Over time, these processes can lead to the disintegration of coal deposits, especially in areas with significant environmental exposure.
When coal burns is it a chemical reaction?
Burning coal is a chemical process in which coal reacts with oxygen and forming carbon doxide and or monoxide.
Is this a chemical change or a physical change - when coal oil and natural gas are decomposed in landfills they produce methane gas?
it is chemical property. they use the word decomposition immaterially shows changein chemical composition.hence chemical change.
What is coals symbol?
Coal hasn't a chemical formula; the major and useful component of coal - carbon - has the chemical symbol C.
Is is a physical or chemical change when natural gas burns in a stove?
Natural gas, gasoline, fuel oil, coal, and LPG burning are all chemical reactions ( chemical changes ). The reactants ( fuel and oxygen ) react yielding primarily CO2 and H2O., which are different chemical species than the reactants.
Is breaking coal into pieces chemical or physical change?
Breaking coal into pieces is a physical change because it does not alter the chemical composition of the coal. The coal remains composed of the same elements before and after being broken into pieces.
Is mining coal a physical or chemical change?
Mining coal is a physical change because the act of extracting coal from the earth does not alter its chemical composition. The coal remains chemically the same before and after the mining process.
Is burning of coal a physical change?
Burning of coal is a chemical change, not a physical change. During the burning process, the chemical composition of coal changes as it reacts with oxygen to produce heat, light, and ash.
Is burning coal an example of a physical reaction or a chemical reaction?
Chemical. It is called combustion.
Is burning coal for a barbecue physical or chemical change?
Burning coal for a barbecue is a chemical change because the coal undergoes a chemical reaction with oxygen in the air to produce heat and light, along with byproducts like carbon dioxide and ash.
Is burning coal a physical change?
No. Burning anything is a chemical change.
Is coal dust chemical or a physical toxicant?
Coal dust is considered a physical toxicant because it can cause harm through its physical properties, such as being inhaled and causing respiratory issues or skin irritation. Chemical toxicants, on the other hand, refer to substances that cause harm due to their chemical properties or composition.
Is burning coal a chemical or physical reaction?
It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.
Is Burning coal physical or chemical change?
Burning coal is a chemical change because it involves a chemical reaction where the coal combines with oxygen to produce new substances like carbon dioxide, heat, and ash. This process results in the formation of different molecules with different properties from the original coal.
Is burning coal for a barbecue a physical change?
Yes, burning coal for a barbecue is a chemical change. This is because the combustion process results in a chemical reaction where the coal combines with oxygen to produce heat, carbon dioxide, and other byproducts.

Is the change of plants remains into coal a physical or a chemical change?
The change of plant remains into coal is a chemical change. This process, known as coalification, involves the chemical alteration of organic material under high temperature and pressure over millions of years, leading to the formation of coal with different properties.
