What chemical compounds are needed for combustion to occur?

Three things are required in proper combination before ignition and combustion can take place—Heat, Oxygen and Fuel.

• There must be Fuel to burn.
• There must be Air to supply oxygen.
• There must be Heat (ignition temperature) to start and continue the combustion process.

What are those chemical that will create a fire?

Fire is the result of a chemical reaction called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced. Flames consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen.

What are the 4 products of combustion?

Products of Combustion

• Carbon Dioxide.
• Carbon Monoxide.
• Sulfur Dioxide.
• Nitrogen Oxides.
• Lead.
• Particulate Matter.

What do explosions have in common with burning?

All explosions, regardless of their source, are characterized by a large release of energy, the production of gas molecules that expand quickly, and a rapid rate of reaction. Burning sugar—chemically known as sucrose (C12H22O11)—produces energy almost immediately.

What causes the fire to burn continuously?

Because of the continual reactions taking place between fuel and oxygen, which generate surplus amounts of heat energy, the flame will always be hot enough to keep the fuel at ignition temperature. Therefore, the fire will continue to burn as long as there is enough fuel and oxygen available.

What are the ingredients of a fire triangle?

Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

What is the composition of air?

Nitrogen — 78 percent. Oxygen — 21 percent. Argon — 0.93 percent. Carbon dioxide — 0.04 percent.

What polluting compounds come from combustion?

Some of the common pollutants produced from burning these fuels are carbon monoxide, nitrogen dioxide, particles, and sulfur dioxide. Particles can have hazardous chemicals attached to them. Other pollutants that can be produced by some appliances are unburned hydrocarbons and aldehydes.

When a hydrocarbon burns in the air what component of air reacts?

Hydrocarbon fuels burn when they react with oxygen in the air. As all hydrocarbons only contain the elements carbon and hydrogen, the only products will be oxides of these elements. So as long as enough oxygen is present for complete combustion, the two products formed will be carbon dioxide (CO 2) and water (H 2O).

Does lithium require oxygen burning?

2. Can lithium-ion batteries burn without oxygen? The lithium-ion battery or Li-ion battery fire does not need any oxygen to burn at all, because it can do that without any oxygen at all. The kind of fire and the expulsion it can cause is unmatched, and very hard to get control over.
