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.
The combustion of methane is exothermic, which means it releases heat energy. This is because the chemical bonds in methane and oxygen are broken and reformed to create new compounds, releasing energy in the process.
This 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, a combustion reaction is typically exothermic because it releases heat energy. Endothermic reactions absorb heat energy from the surroundings.
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?
The combustion of propane in oxygen is exothermic, meaning it releases energy in the form of heat and light. Methane typically produces more energy when combusted compared to propane, as it has a higher energy content per unit mass. Methane is also more efficient in combustion due to its simpler chemical structure, which requires less energy to break its bonds.
What is the incomplete symbol equation for combustion of methane ch4?
The incomplete symbol equation for the combustion of methane (CH4) is CH4 + O2 → CO + H2O.
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.
Are combustion reactions exothermic or endothermic?
All combustion is exothermic. ( i love pie)
Is the combustion of hydrogen exothermic or endothermic?
The combustion of hydrogen is exothermic because it releases energy in the form of heat and light during the reaction.
Is ethanol combustion exothermic?
Yes, ethanol combustion is an exothermic process. When ethanol reacts with oxygen during combustion, it releases energy in the form of heat and light, making it an exothermic reaction.
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 a combustion reaction an endothermic reaction?
No, a combustion reaction is typically exothermic because it releases heat energy. Endothermic reactions absorb heat energy from the surroundings.
What happens when methane combines with oxygen?
When methane combines with oxygen in the presence of heat or a spark, it undergoes combustion to produce carbon dioxide, water, and heat energy. This reaction is exothermic, meaning it releases energy in the form of heat.
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.
Is the Combustion of Hydrogen Endothermic?
No, the combustion of hydrogen is exothermic, meaning it releases heat energy. When hydrogen reacts with oxygen to form water, it releases energy in the form of heat and light.
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?
The combustion of propane in oxygen is exothermic, meaning it releases energy in the form of heat and light.

Methane is also more efficient in combustion due to its simpler chemical structure, which requires less energy to break its bonds.
What is the experimental molar heat of combustion of methane?
The experimental molar heat of combustion of methane is approximately -890 kJ/mol.
