The heat of combustion refers to the energy that is released as heat when a compound undergoes complete combustion with oxygen under standard conditions. The heat of combustion of acetylene at 25 degrees Celsius is roughly around 1300 kJ/mol.

The complete combustion of acetylene C2H2g produces 1300 kJ of energy per mole of acetylene consumed How many grams of acetylene must be burned to produce enough heat to raise the temperature of?
The specific heat, or heat capacity, of the substance having its temperature raised will determine how much the heat affects its temperature. The units of heat capacity are a ratio of energy to the product of mass and temperature degree.
What is the heat of combustion of natural gas?
Natural gas is not just one type of hyrdocarbon, and so its heat of combustion (or enthalpy of combustion) will vary from sources. However, it is primarily formed from methane which has a "heat of combustion" of 889 Kilojoules per mole, you could use that value. Hope that's what you wanted!
What basis are heats of formation and combustion defined?
Combustion in defined in terms of 1 mole of reactant, formation is defined in terms of 1 mole of product
The heat of combustion for 1 mole of carbon to carbon dioxide is -410 kJ How many kJ of heat would be liberated from the complete combustion of 60.0 g of carbon?
60 g of carbon represents 5 moles of the element (Molar mass of C is 12). We can simply multiply the energy released by one mole by 5 to get the answer: 5 x -410 = -2050 kJ
How many moles of oxygen are required to react completely with 1.0 mole of c2h2?
2C2H2 + 5O2 ---->4CO2 + 2H2O so 1 mole of acetylene (ethyne) reacts with 2.5 moles of oxygen. Answer 2.5 moles

What do you call the heat released when 1 mole of a substance undergoes complete combustion?
You think probable to molar heat, expressed in J/mol.

Acetylene gas C2H2 reacts with oxygen If 2 moles of acetylene react completely with oxygen how many grams of carbon dioxide are produced?
First you need to work out the balanced equation. 2C2H2 + 5O2 -----> 4CO2 + 2H2O From this we see that 2 moles of acetylene produces 4 moles of carbon dioxide. 1 mole of carbon dioxide is 12 + 16 + 16 = 44g (adding the mass numbers of the component elements). If 1 mole = 44g then 4 mole = 176g
What is the heat of combustion of dimethyl ether?
I calculated it as approximately -341.76 kcal/mole
What releases water and energy?
Combustion of hydrogen gives a lot of heat and water. The stoichiometric reaction of hydrogen with oxygen is: 2H2(g) + O2(g) gives 2H2O(l) + 572 kJ Hydrogen's Enthalpy of Combustion is 286 kJ/mole
Is this reaction Endothermic The combustion of propane in oxygen to produce carbon dioxide and water vapor. And does methane or propane produce more energy combustion I just dont understand this?
All the combustion reactions I know of are exothermic because heat is released instead of absorbed. And propane gives more energy than methane cause it has more Cs and Hs to react with Oxygen, so one mole of propane will react more and form more product than one mole of methane and giving out more energy.

The combustion of titanium with oxygen produces titanium dioxide.?
When 1.310 g of titanium is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 25.00°C to 68.10°C. In a separate experiment, the heat capacity of the calorimeter is measured to be 9.84 kJ/K. The heat of reaction for the combustion of a mole of in this calorimeter is __________ kJ/mol. 5.97-0.154-3119.43-1.55 × 104
When 2.13 moles of C3H8 burn in excess oxygen how many moles of CO2 will be formed assuming complete combustion?
Out of one mole C3H8 three moles carbondioxide (CO2) are formed by complete combustion of it.So 2.13 mole C3H8 make 3*2.13 mole CO2 = 6.39 moleCO2
