What is the equation for burning hydrocarbons?
The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is: Fuel + O2 → CO2 + H2O.
What happens when a hydrocarbon is burned?
Burning hydrocarbons in the presence of oxygen (O2) produces carbon dioxide (CO2) and water (H2O). If there is too much carbon or too little oxygen present when hydrocarbons are burned, carbon monoxide (CO) may also be emitted. Sometimes unburned hydrocarbons are released into the air during incomplete combustion.
What do hydrocarbons react with when they burn?
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).
What is the chemical equation for fire?
As long as there is enough fuel and oxygen, the fire keeps burning. Fuel + oxygen (from the air) = combustion products (mainly CO2 + H2O) + heat energy.
Which formula represents unsaturated hydrocarbons?
(2) CH2=CH2. – Unsaturated hydrocarbon means the hydrocarbon which contains atleast one double or triple bond between two carbon atoms.
What is the chemical equation for photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What is a word equation in science?
A word equation represents a chemical reaction using the names of the substances involved. Word equations do not show any chemical symbols or formulae.
What is fuel chemical formula?
| Name | Molecular Formula |
|---|---|
| Gasoline is a mixture of many straight chain, branched, and aromatic hydrocarbon molecules in the range of C7 through C11 or 12. | |
| undecane | C11H24 |
| dodecane | C12H26 |
| Kerosene, jet fuel, and diesel fuel contain hydrocarbons in the range of C12 to C20. Fuel Oil has a range of hydrocarbons of C20 to C40. |
What is the chemical equation for hydrocarbon?
General chemical formulas. If a hydrocarbon molecule contains “n” carbon atoms, and the type of hydrocarbon is known, its general chemical formula can be written as follows: Alkane: C nH 2n+2. Cycloalkane : C nH 2n (assuming a single ring, with all the carbon atoms in the ring structure).
What is the incomplete combustion of hydrocarbon?
Incomplete combustion occurs when there is an inadequate or insufficient supply of the oxidant, which may be oxygen gas. An incomplete combustion of a hydrocarbon with oxygen as the oxidant will produce carbon monoxide instead of carbon dioxide.
What are the products of combustion of hydrocarbons?
When combustion occurs for a hydrocarbon fuel, the main products of the chemical reaction are Carbon Dioxide and water. There are also a number of secondary products that can occur. These can be Carbon Monoxide, Hydroxide ions, Nitrogen oxides, and others.
