What is the fibre which is a byproduct of burning coal?
The fiber that is a byproduct of burning coal is called coal ash. Coal ash is a fine powder consisting of mineral particles that are produced when coal is burned at power plants.
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 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 reversible or irreversible change?
Burning coal is an irreversible change because it undergoes a chemical reaction, transforming the coal into ash, carbon dioxide, and other byproducts which cannot be easily reversed to their original form.
What does coal ash form into when burned?
When coal is burned, coal ash forms into a residue that contains various minerals, metals, and other impurities like silica, iron, aluminum, calcium, and magnesium. This residue is commonly known as coal ash or fly ash and is often collected and disposed of at coal-fired power plants.

What you might see when coal is burning to show that a chemical reaction is happening?
Coal changes to ash, flames with heat coming out.
What is another name for a piece of burning wood?

Burning coal is an irreversible change because it undergoes a chemical reaction, transforming the coal into ash, carbon dioxide, and other byproducts which cannot be easily reversed to their original form.
What are benefits of using coal?
One benefit to using coal energy is that the leftover ash from burning coal, called fly ash, can be used to make a cement paste when mixed with alkaline chemicals like sodium hydroxide (NaOH).
What does coal ash form into when burned?
When coal is burned, coal ash forms into a residue that contains various minerals, metals, and other impurities like silica, iron, aluminum, calcium, and magnesium. This residue is commonly known as coal ash or fly ash and is often collected and disposed of at coal-fired power plants.
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.
How many tons of ash Do scrubbers remove each year from the smoke stacks of coal burning?
Scrubbers in coal burning plants can remove millions of tons of ash each year from smokestacks, depending on the size and capacity of the plant. The precise amount removed varies by facility.
Is burning coal a reversible change?
No, burning coal is an irreversible change as it involves a chemical reaction that transforms the coal into new substances such as carbon dioxide and ash. Once coal is burned, it cannot be reverted back to its original form.
What happens to the coal after it is burned?
After coal is burned, it turns into ash. The ash is typically disposed of in ash ponds or landfills, or it can be recycled for use in materials like concrete or asphalt. Burning coal also releases gases and particles into the air, contributing to air pollution and climate change.
