The real reason we don't burn road tar for fuel has to do with the efficiency of the reaction, not the total heat output based on the number of carbons. Reactions in the vapor phase maximize the combustion, so we need a gas or a volatile liquid. This gets mixed with air, then combusted. To use road tar, we would have to either heat the tar up to get it into the vapor phase or make very small droplets before combustion. Tar is more viscous, so it's not easy to make droplets.
The gasoline we use in cars is based on a variety of factors including ease and cost of extracting the components from the ground, refining them into the correct fractions, transport, transfer, and storage of the fuel, safety of the fuel for the public, and efficiency in an internal combustion engine. This is the realm of chemical engineers.
What else can I help you with?
Why alkane make good fuels?
Alkanes make good fuels because they have high energy content per unit mass, they undergo combustion reactions that release a large amount of heat energy when burned, and they are relatively abundant and easily obtainable from fossil fuel sources. Additionally, alkanes burn cleanly and produce less pollution compared to other fuel sources.
Where you can found alkanes in environment?
Alkanes can be found in natural gas deposits, petroleum reserves, and in fossil fuels such as coal and oil shale. They can also be produced by biological processes in anaerobic environments, such as in the digestive systems of animals.
Is the main use for alkenes fuel?
Yes, Alkenes are used for fuels - as they are one of our organic compounds in society. For example, fuel can be used for cooking and petrol.
What is a cracking of a oil fraction?
It is when you break large hydrocarbons/alkanes, into smaller more useful alkanes/alkenes. For example a large hydrocarbon in crude oil is Bitumen. By passing this substance over a hot catalyst, you can break it down into smaller hydrocarbons such as Petrol or Diesel
Hydrocarbons which have only single bonds between carbon atoms?
Alkanes are hydrocarbons that have only single bonds between carbon atoms. They are saturated hydrocarbons with the general formula CnH2n+2, where n represents the number of carbon atoms in the molecule. Alkanes are relatively inert and have straight or branched chain structures.
What are 3 uses of alkanes?
Three uses of alkanes are:used as organic solvents in labs when in liquid formused as a general anaestheticused as fuels because a large amount of energy is released when alkanes undergo combustion.
What is the process that converts large alkanes to small alkanes and alkenes is called?
The process that converts large alkanes to small alkanes and alkenes is called cracking. This process involves breaking down the larger hydrocarbon molecules into smaller, more valuable ones through the application of heat and sometimes a catalyst. Cracking is an important step in the production of gasoline and other valuable fuels.
Oil is and example of?
energy sources: fossil fuels chemistry: alkanes
Benefits of using alkanes as fuels?
i dont know dont ask me.
Why is using alkanes as fuels bad?
Using alkanes as fuels can be bad because they release carbon dioxide and other pollutants when burned, contributing to air pollution and climate change. Additionally, their combustion may lead to harmful effects on human health and the environment. Lastly, alkanes are non-renewable resources that contribute to the depletion of fossil fuels.
Why alkane make good fuels?
Alkanes make good fuels because they have high energy content per unit mass, they undergo combustion reactions that release a large amount of heat energy when burned, and they are relatively abundant and easily obtainable from fossil fuel sources. Additionally, alkanes burn cleanly and produce less pollution compared to other fuel sources.
What are the advantages of Alkanes?
Alkanes have low reactivity, making them stable compounds. They are used as fuels due to their high energy content. Alkanes are also relatively non-toxic and have low environmental impact when burned.
Why alkanes are use as a fuel?
because we use it
What the advantages of using alkanes?
Alkanes are, 1- good fuel, 2-higer alkanes are good lubricants, 3- they are antiseptic for external use.
Why are alkenes good fuels?
Alkenes are good fuels because they have high energy content due to their carbon-carbon double bonds. When burned, alkenes release a large amount of heat energy, making them efficient fuels for heating, transportation, and power generation. Additionally, alkenes are less dense than alkanes, allowing for easier storage and transportation.
Where you can found alkanes in environment?
Alkanes can be found in natural gas deposits, petroleum reserves, and in fossil fuels such as coal and oil shale. They can also be produced by biological processes in anaerobic environments, such as in the digestive systems of animals.
