The standard enthalpy of formation of propene c3h6 is 20.6 kj per mole What is the heat of combustion of one mole of c3h6 the heats of formation of co2g and h2ol are -394 kjmole and -285.8?
Just set up the balanced equation to solve this. C3H6 (s) + (9/2)O2(g) ---> 3CO2(g) + 3H2O (l). Now it is only a matter of adding and subtracting the appropriate formation values.
Give an example of where you can see a chemical reaction take place when a hot air balloon flies?
A chemical reaction takes place every time a hot air balloon flies. Specifically, a combustion reaction occurs when the fire from the propane tank heats the air inside the balloon.
What heats faster water or copper?
copper
Which heats faster iron or copper?
iron
What happens when it is heated?
"It" heats up,unless you were talking about that.
What is the formula for finding heat formation?
Heat of combustion of a hydrocarbon is based on the reaction: fuel + oxygen --> carbon dioxide + water (unless you have some nitrogen or sulfur in the fuel, in which case it gets a little more complex) The heat of formation of O2 is zero (O2 is the reference state) The heat of formation of CO2 is the same as the heat of combustion for carbon The heat of formation of H2O is the same as the heat of combustion for hydrogen To find the heat of formation of the fuel, you subtract the heat of combustion from the heats of formation - (weighted with the stoichiometric coefficients from the balanced reaction equation).
How can stoichiometry be used in tandem with heats of formations to calculate the energy of a reaction?
Through the application of Hess's Law (of Constant Heat Summation) one can use heats of formation to find the overall energy release or requirement. The overall reaction energy is equal to the difference between total heats of formation of the products and the total heats of formation of the reactants.
What does a combustion controller maintain?
A combustion controller maintains how quickly an item heats up, and possible the size of the fire it produces.
What are stages of combustion in CI engines?
Intake, compression, power/combustion, exhaust. Same as a standard SI (Spark Ignition) CI (Combustion Ignition) is how diesel operates. They contain no spark plugs. The compression heats the fuel to the point of SELF COMBUSTION .

Why does kindling make it easier to start a fire?
Kindling has a low mass, thus it heats up to its combustion temperature quickly, and has a high surface area exposed to oxygen, thus allowing free combustion.
Which phase change results in the formation of the tail of a comet?
upon the distance of the sun as it heats up and releases the material on the comet
Why is there a difference in temperature between the intake and exhaust?
Because air outside is generally cooler than where a heat causing engine is. The combustion chamber inside super heats the air
What heats the lava in a volcano?
The lava of a volcano originates from Earth's mantle, which is very hot due to a combination of radioactive decay and residual heat from Earth's formation.
What has the author Albert Marion Hughes written?
Albert Marion Hughes has written: 'Heats of combustion of hydrazine, hydrazine hydrate, and related compounds' -- subject(s): Hydrazines, Thermal properties
What is a protoplanet?
A whirling cloud of gas or dust that becomes a planet by condensation during formation of a solar system. As the central body, or protostar, of the system contracts and heats up
Is friction responsible for the formation of a star?
No. A star forms when gravity causes a nebula to collapse. As the gas compresses it heats up. eventually, the heat and pressure ignite nuclear fusion.
