Endothermic means that the net energy produced when chemical bonds reform is less that the energy required to break the original bonds. (It gets cold because it need more energy from the surrounding molecules)
Exothermic means that the net energy produced is more than the required energy to break the original bonds. (it gets hot because it releases energy)
Using logic and personal experiences, when you ignite something, such as methane, it burns. just the fact that it burns shows that it is releasing energy in the form of light/heat. this makes the combustion of methane Exothermic.

∙ 13y agoThis reaction is exothermic. When methane is combusted, energy is released. One way to tell this is that the products (H2O and CO2) are more stable than the reactant, methane.

Is a combustion reaction an endothermic reaction?
No, it is exothermic.
Are Ombustion reactions exothermic or endothermic?
Combustion reactions are exothermic.
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.

What is the incomplete symbol equation for combustion of methane ch4?
Incomplete combustion of Methane is....2CH4 + 2O2 --> CO + C + 4H2O
What is true about most combustion reactions?
They release energy (they are exothermic).
Is the combustion of methane endo or exothermic reaction?
Let's think about what happens in the combustion of methane. Take natural gas for example (methane) used to heat homes, or used in stoves. The product is heat, therefore heat is given off. Therefore EXOTHERMIC.
Is a combustion reaction an endothermic reaction?
No, it is exothermic.
Is the combustion of hydrogen exothermic or endothermic?
Exothermic.
Why is the burning of methane is an exothermic reaction?
Exothermic is a release of heat, so when methane burns, it must release heat to be exothermic.
Are combustion reactions exothermic or endothermic?
All combustion is exothermic. ( i love pie)
When clothes are drying is it an endothermic or an exothermic reaction?
The combustion is exothermic.
Is the Combustion of Hydrogen Endothermic?
It is Exothermic
Is combustion exothermic or endothermic?
exothermic reactions are the reactions which give out heat and endothermic reactions are the reaction which absorb heat.so combustion is an exothermic reaction.
Is ethanol combustion exothermic?
All types of combustions are exothermic.
Are Ombustion reactions exothermic or endothermic?
Combustion reactions are exothermic.
What kind of chemical changes produces heat?
Exothermic chemical reactions release energy in the form of heat and sometimes light. A common example would be the combustion (oxidation) of methane*:Methane: CH4 + 2O2 -----> CO2 + 2H2O + Energy (heat and light)* The combustion of methane (natural gas) is commonly used to heat water, cook, and to heat homes.
What is the experimental molar heat of combustion of methane?
The standard enthalpy of combustion for methane is -890 kJ/mol.
