It is an endothermic reaction because in endothermic reaction energy is added .In that reaction nitrogen does not react with oxygen without energy added in the shape current . In that reaction 3000`current is applieded to take reaction b/w nitrogen and oxygen

Is combustion of magnesium reaction with exothermic or endothermic?
If you mean the enthalpy of formation then no, it is exothermic.
What is 2 examples or an exothermic reaction?
Burning wood is exothermic and photosynthesis is endothermic.
How does the reaction between wet iron filings air and salt happen to produce heat?
It is the oxidation of Iron to Iron oxide. An exothermic reaction.
Why do endothermic reactions need additional energy to keep going while exothermic reactions don't?
Ipso facto. An endothermic reaction "absorbs" energy (uses it to create high-energy bonds), so this must be constantly supplied from an external source. An exothermic reaction "releases" energy, and this energy can be used to continue the reaction until there are no reactants remaining.This is why stellar cores cannot fuse massive quantities of elements heavier than iron. The reactions are not self-perpetuating as they are absorbing energy rather than releasing it. A large, inert iron core is the result.
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
Is the chemical reaction for aluminum exothermic or endothermic?
Yes it is. When these two chemicals react, the container they are in becomes heated. Exothermic refers to a release of heat and energy.
Is combustion of magnesium reaction with exothermic or endothermic?
If you mean the enthalpy of formation then no, it is exothermic.
What is 2 examples or an exothermic reaction?
Burning wood is exothermic and photosynthesis is endothermic.
Is rusting metal exothermic or endothermic?
It is an exothermic reaction. However, rusting of iron liberates only a small amount of heat as compared to other forms of metal corrosion.
Is fusion an endothermic reaction?
It depends on what is being fused. Fusion usually takes place with elements lighter than iron, mostly hydrogen. in those cases it is exothermic. Fusin elements heavier than iron is endothermic.
Is reduction of hematite to iron endothermic?
This reaction is endothermic.
Is iron rusts a physical or chemical reaction?
Iron rusting is a chemical change.
Is iron rusts chemical or physical?
Chemical reaction from water
What chemical reaction takes place when an iron nail rusts?
Rusting is an oxydation reaction.
Is melting of iron in furnace exothermic?
Neither endothermic nor exothermic. These two terms apply to chemical reactions, wether they require or produce energy (heat). Melting iron isn't a chemical but a physical reaction, a change of phase, solid to liquid. Iron is solid at room temperature, we heat it to melt it, so heat is added (which is the same as the principle of endothermic, heat is absorbed, it must be heated)
Is rusting of iron an endothermic process?
According to the definition of an exo/endo-thermic compound, all metallic oxides (rusty metals) are exothemic compounds, since their forming reaction starting from elemenets (Me + O2) is called rusting as an example of an exothermic reaction.
Is iron rusting a exothermic reaction?
the tune of Iron from about -60 to -190 kcal/mol, substantial amount of heat gnerated so the reaction is exothermic.
