It is an exothermic reaction. There are multiple ways to think about this. The reactants are in the gas phase and thus have a lot of energy within the molecules. When they react to produce a liquid, which has much less energy in its molecules. The energy must be released to the environment to lower the energy of the bonds.

∙ 13y agoI don't understand the question. Are you trying to ask what kind of reaction it is? It's a combustion reaction. You could also consider it a redox reaction, since the hydrogen is being oxidized and the oxygen is being reduced.

Is a road flare exthermic or endothermic?
Exothermic, because it releases heat as a form of energy.
If it absorbs heat is it exothermic or endothermic?
endothermic
Which of the following is described by the equation H2O l plus heat H2Og?
Evaporating -apex
What processes are endothermic?
During an endothermic process heat is absorbed.
Does the endothermic process take in heat from its surroundings?
Yes, an endothermic process requires heat.
Is a road flare exthermic or endothermic?
Exothermic, because it releases heat as a form of energy.
What heat transfer associated with a chemical reaction or pharse changs as either exthermic or endothermic?
to see your mom.
What is a chemical reaction that absorbs heat?
An endothermic reaction absorbs heat, an exothermic reaction releases heat.
What is an exthermic?
I think you meant Exothermic. Anways... that is a process releases energy usually in the form of heat.
Is vaporization exothermic or endothermic?
It is endothermic. Endothermic is to gain heat and Exothermic is to lose heat.
What happens in an endothermic reaction?
An endothermic reaction need heat to occur.
A reaction that absorbs energy is called?
Endothermic-take in Heat, as opposed to exothermic which gives off heat-like a fire or explosion.
Which of the following is described by the equation H2O l plus heat H2Og?
Evaporating -apex
If it absorbs heat is it exothermic or endothermic?
endothermic
What is the name given to reactions which take in heat?
An endothermal (or endothermic) process is the name of the process in which heat is taken in. In an exothermal (or exothermic) process, heat is released.
What contrast endothermic and exothermic changes?
Exothermic: release of heat Endothermic: absorption of heat
What processes are endothermic?
During an endothermic process heat is absorbed.
