17 янв. 2019 г. · Breaking a bond, in isolation, never releases energy. Bonding is a stable state compared to the unbonded species, where opposite charges are ...

13 авг. 2020 г. · It is easy to understand that breaking a bond requires energy because it can be viewed in many ways like breaking a wood into pieces requires energy.

1 апр. 2019 г. · Still, energy is not released when a bond is broken, even in an exothermic reaction. You need to separate two atoms which have an attractive ...

17 сент. 2014 г. · Energy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process.

25 апр. 2015 г. · The potential energy of a system increases when the bonds present in it are broken (ie, when a solid turns into a liquid.)

13 авг. 2014 г. · Breaking chemical bonds does not turn their potential energy into kinetic energy. All bond dissociation enthalpies are positive (for stable bonds that actually ...

24 мая 2019 г. · If you break a bond in a diatomic molecule then all that can happen is that the two atoms move away from one another with the excess energy used ...

5 дек. 2016 г. · As a general rule, bond-breaking is indeed endothermic (requires energy applied to break the bonds) whereas bond-making is exothermic (outputs energy).

6 дек. 2021 г. · Better is to say "Energy released by forming bonds of combustion products is bigger than the energy needed to break bonds of combustion ...

28 дек. 2017 г. · Bond breaking does NOT release energy!! In the course of a chemical reaction, you typically break some bonds and form some new bonds.
