Combination and decomposition reaction | Chemical reactions and equations | Chemistry | Khan Academy

Reactions in which many reactants combine to give one product are called combination reactions whereas, in decomposition one reactant breaks down in many products

I am from Sri Lanka. This wonderful lesson is helpful for our chemical decomposition and chemical combination reaction lesson. Thank you sir🙏🏻🙏🏻🙏🏻🙏🏻

Thank uhh sir so much uhh are great 👍👍👍👍❣️

Thank you so much sir

Sir, will the weight of MgO be more as compared to the magnesium ribbon taken ?Since it is a combination reaction!

[@JkVerma-ld1xi]

VERY GOOD ACADEMY

[@tvasia2083]

Can you tell how are you finding the reaction of the two elements do we have to byheart it or there is way for finding the reaction

Great work

[@ishika6802]

Thanks a lot 😊 sir

[@AJ-lh9cg]

I have a question Why it happens that when we burn some substance in the air it always reacts with oxygen only because there are even more gases in the air except oxygen?

[@ishika6802]

Because combustion can happen only in the presence of oxygen

[@mahijha3114]

Because oxygen is the most reactive gas present in the atmosphere . Noble gasses are inert and carbon dioxide is also mostly inert . oxygen is also the most reactive non metal .

Hello I have a doubt In endothermic reactions we supply heat then mg + O2 should also be endothermic as we used heat then why it is exothermic

[@shreyanshtalks9276]

@@shivang5862 no it is exothermic bcoz Heat is released while this reaction takes place.. Heat released and absorbed is relative term.. Like if u r saying certain reaction is exothermic then it is not necessary that heat is not absorbed.. The primary reason is that The heat released is much more higher than the heat absorbed.. Hope O coud explain it to u:)

​@@shivang5862no dude it's exothermic reaction not endo.

[@vibhapathak4047]

​@@shivang5862we don't supply heat to it while it reacts heat energy releases
