Any sort of combustion is exothermic.
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.
the answer is exothermic because heat is being released
because its simply a hydrocarbon. Hydrocarbons cannot produce and endothermic energy when reacted.
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Exothermic. Carbohydrates + oxygen (from respiration) yields CO2, H2O and heat.
Steam itself is not endothermic or exothermic - only chemical reactions can be labelled as exothermic or endothermic the reaction whithin the steam can only be exothermic or endothermic
Reactions with oxygen (air) involved, like burning paper, are exothermic. Exception: formation of many nitrogen-oxygen compounds (NOx) are endothermic.
endothermic because energy is being absorbed
It is endothermic!
It is endothermic. Endothermic is to gain heat and Exothermic is to lose heat.
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.
No. It is endothermic as it requires energy.
Silicon is an element - endothermic or exothermic is meaningless.
endothermic on formation exothermic on oxidation
aerobic respiration is exothermic and photosynthesis is endothermic
Like all burning reactions (with oxygen that is) burning wood is also exothermic.
exothermic- because exothermic gives off heat and endothermic is cold
