Question

someone told me to post here because theres not enough people in physics.

4. Describe in detail the relationship between chemical bonds and energy. What must be true of the bonds for a reaction to be endothermic, and what must be true for the reaction to be exothermic?

Answer 1

and by physics you mean chemistry?

Answer 2

lol

Answer 3

lol :D

Answer 4

ok i can explain it for you :)

Answer 5

well I wasn't sure where to really post it @zzr0ck3r

Answer 6

I take M/J Comprehensive Science 3 V8 for 8th grade

Answer 7

ok listen

Answer 8

chemical bond is a force which binds the atoms while when we break that bond energy evolve

Answer 9

now those bonds in which when atoms combine with each other to make new compound and during this process if they lose heat into atmosphere then this bond will be exothermic .
and if you use the heat of atmosphere to be combined then this bond will be endothermic .

Answer 10

Any time that a bond is formed, energy is released. Likewise, any time that a bond is broken, energy must be supplied.

In an endothermic reaction, the energy required to break the bonds in the reactants must be greater than the energy released forming the bonds in the product.

For an exothermic reaction, the opposite will be true: More energy is released in forming the bonds of the product than is absorbed to break the bonds in the reactants.

Answer 11

in an endothermic reaction energy is consumed so the energy of bonds of products is higher than the bond energy of reactant. The consumed energy increases the bond energy of product.

in an exothermic reaction energy is given out so can u cmnt upon the bond energies of reactants nd products? :)

Answer 12

okay I think that should help. thank you guys @sohailiftikhar @RainbowBrony555 @imqwerty

Answer 13

np :)

Answer 14

no prblm :D

Answer 15

no problem ^_^

Answer 16
