# Frequent question: What is the equation of burning of coal?

Contents

Burning any material, has the same equation: fuel + ignition source + oxygen equals combustion. Fuel can be coal, wood, gasoline. Anthracite (hard) coal will produce 14K but per pound or 6 pounds will produce about the same heat as a Therm of natural gas or a gallon of propane.

## What is the chemical equation of burning of coal?

Following chemical reactions takes place in the combustion of coal with the release of heat: C + O2 = CO2 + 8084 Kcal/ Kg of carbon (33940 KJ/Kg) S + O2 = SO2 + 2224 Kcal/Kg of sulfur (9141 KJ/Kg) 2 H2 + O2 = 2 H2O + 28922 Kcal/Kg of hydrogen (142670 KJ/Kg)

## Is burning of coal a combination reaction?

Answer. Answer: A combustion reaction is when a chemical reacts with oxygen and releases energy. Fuels are burnt to produce energy when these fuels burn, the atoms in the fuels combine with oxygen from the air to make new molecules, that is the reason why the burning of coal is a non-reversible chemical change.

## Which gas is formed by burning of coal?

carbonic oxide (CO)

## What happens when coal is burned in air?

Charcoal reacts with oxygen of the air at a glowing red heat to form colourless carbon monoxide gas, which then burns with a blue flame with more oxygen from the air to produce carbon dioxide gas. … Unburned carbon monoxide gas can be given off by burning charcoal.

## Does coal burn with glow?

(i) A coal or charcoal burns with just a glow red and gives out heat without flame however LPG burns with flame, this is because a flame is produced only when gaseous substances burn.

## Does coal ignite easily?

Coal, and particularly brown coal, is very reactive to oxygen, and will generate CO2 and that creates heat. As the coal gets hotter it will eventually get to flame temperature and that coal will burn.”

## Is burning coal reversible?

Burning of coal is a chemical change. When coal is burnt, the chief component, carbon is changed to carbon dioxide. This process cannot be reversed.

## What happens when coal is burned?

What Happens When We Burn Coal? When coal is burned, it reacts with the oxygen in the air. This chemical reaction converts the stored solar energy into thermal energy, which is released as heat. But it also produces carbon dioxide and methane.

## Which is the best quality of coal?

Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter.

## What is the chemical name for coal?

It contains mostly methane, a simple chemical with the formula CH4. That means there are four hydrogen atoms for each carbon atom, the maximum a single carbon atom can accommodate. Coal’s chemical formula is far more complex (as we’ll see later).

## Is coal a pure carbon?

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.

## At what temperature does coal ignite?

Ignition temperature of coal and other dust is not affected by particle size. A big difference is made by the way coal dust comes in contact with a heat source. Thus, layered powder of coal can ignite at a much lower temperature (160°C approx.), whereas a cloud of coal dust will need 450–650°C to ignite.

anthracite coal

## Why is coal bad for the environment?

The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. … Coal-fired power plants release more greenhouse gases per unit of energy produced than any other electricity source (1).
