Endothermic reactions need energy to occur
When a fuel is combusted with dioxygen, typically an EXOTHERMIC reactions occurs, with the release of energy, and the energy can be used to do useful work:
CH4(g)+2O2(g)→CO2(g)+2H2O(g)+Δ
Where Δ=Energy.
This energy can be quantified on the basis of the amount of fuel used.
On the other hand, a reaction that requires energy, i.e. where energy is treated as a reactant is classified as an endothermic reaction.
CaCO3(s)+Δ→CaO(s)+CO2(g)
CO2(g)+Δ→C(s)+O2(g)

feel free to ask
well.. that's so stupid to ask doubt who have just copied the answer from net
if you didn't find it helpful its no use saying a thank you ask about it and understand it first
yeah i just pasted it from socratic but you know what endothermic reactions are an easy part and nobody wants to write that whole thing i can explain if you want though but if you're still think i cant help i just pasted an answer from the net feel free to avoid me
you can aldo understand it on the basis of activation energy from chemical kinetics
also*
that doesn't mean you will copy!
u know the answer mean you can answer on your own.. it doesn't make any sense to copy
u know the answer mean you can answer on your own.. it doesn't make any sense to copy
well nobody including me is going to write that long paragraph just for anyone else i just entered the community I'm not going to write a whole paragraph fir you I'll always make my task easier if there is any easy alternative i would choose it and if anyone has any doubts I can clear it and the answers on socratic are pretty good if you would be using it you would have known it but its okay
you have done it.... preety cool... but your answer will soon be deleted ... goodbye
ok sorry i dont have time complain dlete do whatever you want ok cool but just stop comenting now if you feel ofended by my any comment sorry but please end this I lose okay I lose yeah I did mistake copy pasting the answer

Howdy, buddy!
Reaction which requre energy to perform, is called as exothermic reaction.
Here are some examples of such reaction:
C(s) + O₂(g) → CO₂(g) + Heat energy
Zn + 2HCl → ZnCl₂ + H₂ + Heat
Hope it helps!
I think its partially wrong in exothermic reactions only a little activation energy is required like all other reactions but endothermic reactions require more energy to break the bonds and as it consumes heat energy
in exothermic reactions we get energy we don't need to have a constant supply of energy
