What is the energy per mole for the combustion of octane?
Molar Heat of Combustion (molar enthalpy of combustion) of Some Common Substances Used as Fuels
| Substance (fuel) | Molar Heat of Combustion (kJ mol-1) | ΔHreaction (kJ mol-1) |
|---|---|---|
| ethane | 1560 | ΔH = -1560 |
| propane | 2220 | ΔH = -2220 |
| butane | 2874 | ΔH = -2874 |
| octane | 5460 | ΔH = -5460 |
What is the balanced equation for the combustion of octane?
Is 2 C8H18 + 25 O2 = 18 H2O + 16 CO2 correct? Yes, Yancarlo, you have it right. Completely burning a fuel that contains C produces CO2(g); if the fuel contains H, H2O(l) is also produced. Any oxygen that was present in the fuel will end up in the carbon dioxide and water.
What is combustion system?
Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture. In an internal combustion engine (ICE), the ignition and combustion of the fuel occurs within the engine itself. The engine then partially converts the energy from the combustion to work.
Which gas is released when human body is burned?
This assumption is based on the fact that sulphur dioxide is released when bodies are burned.
Which gas is released when human body is burnt?
However, gaseous emissions are by far the greatest source of cremation pollution. In addition to harmless compounds such as water vapor, emissions include carbon dioxide, carbon monoxide, nitrogen oxide, sulphur dioxide, hydrogen chloride gas, hydrogen fluoride, mercury vapour .
Can bones burn to ash?
It is important to note that the skeleton does not ‘turn to ash’ upon burning. Even within modern crematoria, which burn efficiently and at high temperatures, the skeleton will survive.
Which part of human body does not grow?
Stapes
