Except where otherwise noted, data are given for materials in their (at 25 °C [77 °F], 100 kPa). Y ( Y N?) Decane is an with the C 10H 22.

The second product is an alkene, so it will follow the rule C nH 2n. C 16H 34 is an alkane which can be used as the starting chemical in cracking. One of the products of cracking this compound is an alkane which has 10 carbon atoms in it. Write a balanced symbol equation for this cracking reaction. A brief description of the difference between thermal and catalytic cracking of alkanes. This is done by passing decane over a powdered aluminium oxide catalyst at 500°C. I) Balance the equation: Decane ethene + octane C10H22 C2H4 +. [1] ii) Suggest why the decane MUST be heated before cracking can occur.

Although 75 structural are possible for decane, the term usually refers to the normal-decane (' n-decane'), with the formula CH 3(CH 2) 8CH 3. All isomers, however, exhibit similar properties and little attention is paid to the composition. These isomers are. Decane is a component of (petrol). Like other alkanes, it is a solvent, does not dissolve in, and is readily combustible.

Although it is a component of fuels, it is of little importance as a chemical feedstock, unlike a handful of other alkanes.

What is the Chemistry of the Cracking of Hydrocarbons? This means that large hydrocarbon molecules break into smaller molecules when they are heated. The hydrocarbons are boiled and the hydrocarbon gases are either mixed with and heated to a very high temperature or passed over a hot powdered aluminium oxide. The catalyst works by providing the hydrocarbon gases with a for the cracking to take place. For example, decane (an with 10 carbons) can be cracked to produce octane and ethene.

Decane octane + ethene. C 10H 22 (g) C 8H 18 (g) + C 2 H 4 (g) Octane is used as. Is used in the manufacture of. Cracking an produces a smaller alkane plus an. If you add up the number of hydrogen atoms in the above reaction, you will see that there are 22 on each side. An alkene is produced because the original alkane does not have enough hydrogen atoms to produce two more alkanes.
