It depends on the fuel. If it is a fossil fuel you are always going to get carbon dioxide (CO2) and sometimes sulfur dioxide and other gases. But if you burn fuels like bio-gas you get less carbon dioxide emitted (released) and water vapour.
Glucose is the primary fuel burnt in cellular respiration. It is broken down in a series of steps to produce energy in the form of adenosine triphosphate (ATP) which cells use for various functions.
When fuel is burnt, the chemical reaction typically involves the combustion of hydrocarbons (such as octane in gasoline or methane in natural gas) with oxygen from the air to produce carbon dioxide (CO2) and water (H2O) as the main products.
A burnt out piece of coal is one that has already undergone combustion and no longer contains enough energy or fuel to burn effectively. It appears as a charred, blackened fragment that is no longer useful for producing heat or fire.
Fuel is burned to release energy in the form of heat, which can be used to generate power or propel vehicles. The process involves combining the fuel with oxygen in a controlled manner, resulting in a chemical reaction that releases heat energy. This energy is harnessed for various purposes, such as heating buildings, generating electricity, or powering engines.
If it's a fossil fuel, then the gases produced are mainly CO2 (carbon dioxide). Other gases include sulphur and sometimes methane
Fuel is mixed with air, compressed then ignited.
It is burnt.
The wooden houses were the main fuel for the fire.
Fossil fuel is bad because it is not reusable. Once we take all of it from the earth, there won't be any left. To make energy, the fossil fuels must be burnt. The smoke that is released after it is burnt has carbon dioxide and other chemicals that are harmful to nature.
