Is combustion of Hydrogen gas Exothermic or Endothermic?
H2 + O2 = H2O
|
|
|
|
|
|
|
|
ur eqn shiud be H2+1/2 O2------>H2O
yes its exothermic and the heat of combustion is very high.so it is used in fuel cells,u will learn it in 11th and 12th.

be cool,
tomorrow is what we make it today,
so if u can dream it , u can make it .

no all combustion reactions are exothermic

FAILURE IS NOT FALLING IN LIFE BUT NOT RISING AGAIN AFTER FALLING!!!!!!
I LIKE WAVES NOT BECAUSE THEY RISE AND FALL..
BUT BECAUSE EVERYTIME THEY FALL THEY RISE AGAIN!!!!!!!

EXOTHERMIC
USED IN FUEL CELLS WHICH ARE USED IN INTERSTELLAR SPACESHIPS AND SPACE ROCKETS
AND THE BY PRODUCT WATER IS USED FOR DRINKING N IRRIGATION!!!!!!
THERE IS NO COMBUSTION REACTION WHICH IS ENDOTHERMIC
BUT YES COMBUSTION IS NOT SPONTANEUS IT REQUIRES ACTIVATION ENERGY IN FORM OF SPARK!
