Changing dodecane into smaller molecules is useful for several reasons. Smaller molecules are often more reactive and easier to manipulate in chemical reactions, making them valuable intermediates for producing a variety of products such as fuels, solvents, and chemicals. Additionally, smaller molecules have lower boiling points and are easier to transport and store. The process of breaking down dodecane into smaller molecules can also help improve the overall efficiency and sustainability of the chemical industry.

How did chemistry change crude oil to useful materials?
Crude Oil is a mixture of various chemicals, the vast majority being 'hydrocarbons' made from Hydrogen and Carbon atoms only. When they are all mixed together, they have no particular use (crude oil without refining is pretty useless!). However,these hydrocarbon molecules form in chains a bit like necklaces, the longer the chain, the the higher the boiling point (longer chains tangle up). This means that they can be separated by using a process called 'fractional distillation'. Once separated, each hydrocarbon fraction has different properties. In general terms, the smaller the chain, the more useful it will be. Smaller molecules would have a lower boiling point (separate more easily), be more flammable (they need less Oxygen to burn) and be less viscous (all as a result of being made from smaller molecules which don't 'tangle' together). The longer chains like bitumen, can actually be 'cracked' into smaller chains in order to make more useful products like propane. This also forms molecules with 'double bonds'. These can actually be stuck back together to form unnaturally long molecules in a process called polymerisation. This forms molecules not found in nature which can have useful properties. Plastics and man made fibres can be made in this way.
Why are models of atoms and molecules useful in understanding the behavior of matter?
Models of atoms and molecules are useful in understanding the behavior of matter because they help us visualize and predict how atoms and molecules interact with each other. These models provide a simplified representation of complex structures, allowing scientists to study and explain various properties and behaviors of matter at a molecular level.
What are three of charged biomolecules that electrophoresis is particularly useful in separating?
Electrophoresis is an analytical technique used to separate charged molecules based on the migration of molecules in an electric field. It is particularly useful in separating molecules such as: Deoxyribonucleic acid (DNA) Ribonucleic acid (RNA) ProteinsIt is commonly used as a diagnostic tool for detecting genetic mutations determining DNA sequencing and diagnosing certain diseases.
What type of reaction is cracking?
Cracking is a type of thermal decomposition reaction where larger hydrocarbon molecules are broken down into smaller, more useful molecules like alkenes and shorter-chain hydrocarbons. It is commonly used in the petroleum industry to produce gasoline and other valuable compounds from crude oil.
Why is hydrocarbon important?
it makes smaller molecules which is more useful.
The controlled process by which hydrocarbons are broken down or rearranged into smaller more useful molecules is called?
The controlled process by which hydrocarbons are broken down or rearranged into smaller, more useful molecules is called catalytic cracking.
Why is cracking useful?
cracking is useful because large hydrocarbon molecules are broken into smaller ones. And these are needed for petrol and are more reactive.
Why are cracking large hydrocarbon molecules more useful than the original large molecules?
Cracking large hydrocarbon molecules produces smaller molecules that are lighter and have higher demand in the market, such as gasoline, diesel, and jet fuel. These smaller molecules are more volatile and easier to transport and utilize in various industries like transportation and manufacturing. It also helps to maximize the yield of valuable products from crude oil.
What is a process where molecules are split into smaller more useful molecules?
The process you are referring to is called chemical degradation or breakdown. By breaking down larger molecules into smaller, more useful molecules, this process helps to release energy, provide building blocks for biosynthesis, or allow for easier excretion of waste products. Key examples include digestion of food in the body or breakdown of organic matter in composting.
Are anabolic reactions called synthesis reactions?
Catabolism is breaking molecules down into smaller molecules (to get energy). You can remember this if you've ever had a cat -- they break things. Anabolism is the opposite: building things up (to make useful stuff). Now look up the definition of synthesis.

What is achieved in the process of cracking?
For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in. Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules. Cracking is an example of a thermal decomposition reaction." Sources:http://www.bbc.co.uk.education2020.us/
