Can you relate exothermic and endothermic reactions to the making and breaking of bonds?

Bond breaking is endothermic, which means it takes energy. An example would be breaking a window. Bond making is exothermic, which means it releases energy. An example would be burning a substance.

can you relate endothermic and exothermic reactions to specifically the making and breaking of bonds?
Breaking a chemical bond is endothermic and making a bond is exothermic.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
How is heat from the sun an exothermic reaction?
Exos= outside , thermos=temperature or heat So within the definition itself it can be known that in exothermic reactions heat is released. In chemical reactions the energy supplied is use in breaking of bonds, but energy is release by making bonds. In exothermic reactions, the energy supplied is sufficient for chemical reaction to occur (to break existing bonds) and the excess energy is given in the form of heat (from making new bonds).If the reaction is exothermic, it means that the total energy it took to break the bonds is less than the total energy released when forming new bonds -- so net energy is released in the form of heat. for example 2H2 +O2 ----> 2H20 which is exothermic reaction. Combustion reactions in general are exothermic reactions.
Is bond making exothermic or endothermic?
Bonds are both broken and made in an exothermic reaction, but in the end, the potential chemical energy of the products is less than the potential chemical energy of the reactants.
When iron rusts is it an endothermic or exothermic reaction?
It is an endothermic reaction because in endothermic reaction energy is added .In that reaction nitrogen does not react with oxygen without energy added in the shape current . In that reaction 3000`current is applieded to take reaction b/w nitrogen and oxygen

Breaking a chemical bond is endothermic and making a bond is exothermic.
Is bond breaking an endothermic or exothermic process?
Breaking bonds produces energy making it an exothermic process.
Is sparkler burning endothermic or exothermic?
Endothermic reactions take in heat from the surroundings (and make it cooler), exothermic reactions give out heat to the surroundings making it hotter. Get too close to a sparkler and you'll find it is very hot! This is because it is an exothermic reaction.
Is making microwave popcorn endothermic or exothermic?
endothermic :)
Is making aluminium by electrolysis exothermic?
No, it is endothermic
What happens in a exothermic reaction?
In an exothermic reaction, the total making and breaking of bonds results in a net release of energy.
Is thermal decomposition a endothermic or exothermic reaction?
Thedecompositionof water is endothermic since energy is required to break up the bonds between the hydrogen and oxygen in the water molecule. Therefore the decomposition of water absorbs energy, making the reaction an endothermic one.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
What else could exothermic and endothermic reactions be used?
They could be used for making science test or other things, per example: Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.

What is the difference between endothermicand and exothermic reaction?
An endothermic reaction absorbs energy, making its environment cooler. Ab exothermic reaction releases energy, making its environment warmer.
What is an exotherm?
In this process bond breaking always requires energy while bond making always release energy. The balance between these two processes result in two types of reactions exothermic and endothermic reaction. When the energy released by bond forming is greater than the energy consumed by bond breaking there is a net release of chemical energy. This type of reaction is called exothermic reaction+ it is a chemical reaction that releases energy in the form of light or heat.
