Exothermic reactions release energy. Where is the energy used for these reactions to occur stored? .
Tanya [424]

Answer:

In the chemical bonds.

Explanation:

There are different types of chemical bonds, some store a TON of energy while others do not store as much. You can think of it like this: for bonds with low energy, it takes a LOT of force to pull them apart, meaning they are strong bonds. However, this way, you have to put energy into them to break the bonds and form a chemical reaction. This is an endothermic reaction, a reaction that absorbs heat from its surroundings.

Instead, bonds in exothermic reactions are BEGGING to form a more stable bond, and hence store a lot of potential energy. Due to the difficulty of maintaining these bonds, there is a lot of energy put into them. If you break them, however, (exothermic reaction) the energy is released, and hence the exothermic reaction happens.

Hope this helped. Please give Brainliest! :>

sdas [7]
B. Representative electrons

Firstly it is best to describe the shape and structure of an atom, an atom's system and structure is like of the solar planet, the heliocentric view where the sun is the neutrons and protons and the planets are the electrons. Moreover, the electrons are outside these neutrons and protons surrounding the entire system of its atomic structure. Its movement is like of a planet. 

<span>An energy level also known as electron shell, or just shell is a location around an atom where electrons with a specific  energy value,  or quantum number may be found.</span>
