Which is good fuel CH4 or C2H6?
the standard enthalpy kf formation of CH4,C2H6,CO2 and H2O are -74.8,-84.6,-393.5, -286KJ/mol. Dear student, For this question we have to calculate enthalpy of combustion for each specie. Clearly C2H6 is a better fuel as it releases maximum amount of energy.
What are the different types of fuel explain all types with examples?
Chemical
| Primary (natural) | Secondary (artificial) | |
|---|---|---|
| Solid fuels | wood, coal, peat, dung, etc. | coke, charcoal |
| Liquid fuels | petroleum | diesel, gasoline, kerosene, LPG, coal tar, naphtha, ethanol |
| Gaseous fuels | natural gas | hydrogen, propane, methane, coal gas, water gas, blast furnace gas, coke oven gas, CNG |
Would ch4 be an efficient fuel molecule?
Methane burns more efficiently than coal, making it a better option, carbon-cost-wise and air-pollution-wise, than coal.
What are good fuels?
GoodFuels is a pioneer, global market maker and market leader in truly sustainable biofuels. Our goal is to create a better world by accelerating the energy transition in these transport segments for which biofuels are one of the best or only viable alternatives in the foreseeable future.
What is the chemical name for c2h6?
ethane, a colourless, odourless, gaseous hydrocarbon (compound of hydrogen and carbon), belonging to the paraffin series; its chemical formula is C2H6. Ethane is structurally the simplest hydrocarbon that contains a single carbon–carbon bond.
Is CH4 polar?
Methane (CH4) is a non-polar hydrocarbon compound composed out of a single carbon atom and 4 hydrogen atoms. Methane is non-polar as the difference in electronegativities between carbon and hydrogen is not great enough to form a polarized chemical bond.
What is a good fuel class?
A good fuel is one which is cheap, easily available, easy to handle, transport, has proper ignition temperature and high calorific value.
Which is better fuel methane or ethane?
As a fuel? Liquid ethane has 70\% more BTUs per cubic foot than methane, and is low in sulphur. It releases less CO2 than gasoline, and you get twice the range with liquified ethane then methane.
What bond is CH4?
covalent bonds
Methane, CH4, is a covalent compound with exactly 5 atoms that are linked by covalent bonds. We draw this covalent bonding as a Lewis structure (see diagram). The lines, or sticks, as we say, represent the covalent bonds.
What is the heat of combustion of CH4 C2H6 C2 H4 and C2H2?
Heats of combustion of CH4,C2H6,C2H4 and C2H2 is – 212.8, – 373.0, – 337.0 and – 310.5 kcal respectively at the same temperature. The best fuel among these gases is:
Why is H2 closer to an ideal gas than AR?
Perhaps counterintutively, it is not Ar. H2 is closer to ideal gas. Ideal gas assumption that there are no interactions between particles is closer to true for H2, as evidenced by its boiling point of 20.3 K, whereas the bp of Ar is 87 K. The lower bp shows the intermolecular attractions for H2 are less than the interatomic attractions for Ar.
Why is ethane not an ideal gas?
Methane, at room temperature, is also closer to its boiling point, than He or H2, and gases, generally, approach ideal gas behaviour as their temperature becomes further and further away from their boiling points. Ethane is very far from being an ideal gas. It suffers from the same adverse properties as methane, only more so.
