Which type of reaction is burning of coal?

Is burning of coal a combination reaction?

Combustion Reactions: Combustion of coal and combustion of hydrogen are examples of combination reactions.

Is burning of coal is an endothermic reaction?

Answer: Burning coal is a chemical change called combustion. A combustion is the chemical reaction (redox reaction) of coal with oxygen O2. It is exothermic, which means it releases energy : hence the heat.

Is burning coal and exothermic reaction?

To release this energy, we burn the coal. This is an exothermic chemical process called combustion. It releases energy stored in the chemical bonds that hold the molecules together. … Overall, the reaction is exothermic–energy is released.

What is the process of burning coal?

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Is burning coal complete combustion?

Complete combustion produces 394kJ/mol of heat energy which is three times of partial combustion which produces only 111kJ/mol of heat energy [36].

Is melting endothermic or exothermic?

Because the substance is melting, the process is endothermic, so the energy change will have a positive sign.

Is melting ice exothermic or endothermic?

Basically, melting ice is an endothermic reaction because the ice absorbs (heat) energy, which causes a change to occur.

Why is burning a fossil fuel exothermic?

During exothermic reactions (like combustion), bonds are broken, which allows the energy trapped in the bonds to be released and do work. During combustion of fossil fuels, the carbon compound in the fossil fuel reacts with oxygen in the presence of a heat source to form carbon dioxide (CO2) and water.
