Energy is added to break bonds, so there is your simple answer. But some bonus info for you:
Bond energy is the amount of energy it will take to break a bond (ironic, because it sounds like the amount of energy it will take to MAKE a bond, even though it's the opposite).
Energy is released when bonds form, and the same amount of energy is released when the bond is broken.
Metabolism
That process is called a chemical reaction.
Chemical weathering and physical weathering are two types of weathering involved in the phosphorus cycle. In chemical weathering, a chemical reaction causes phosphate rocks to break down and release phosphate into soil. Acid precipitation and the chemicals released by lichen can cause the chemical weathering. In physical weathering, processes like wind, rain, and freezing releases particles of rock and phosphate into the soil.
Indeed by the Law of Conservation of Mass, mass cannot be lost or gained through a reaction. Similarly, atoms cannot be lost, gained or somehow transformed themselves-only rearranged into different compounds. This means there are still going to be the same amount of Hydrogen atoms after a reaction as there were before.
It depends on the nature of the decomposition. if you are talking about biodegradeability in a substance, then no, its decomposition is mainly due to bacteria that will break down the various particles in the substance ("eat" them). There are, however certain chemical reactions which take place within the bacteria as the substance is being broken down, (much like those that happen in the human body) and the possibility of there being other products in the vicinity which may react to the substance (and degrade it) is always present. It could be said that decomposition is therefore a chemical reaction (or rather a series thereof), but with biodegradeability in mind it is not generally thought of as such.
Heat can be used to break compounds because there is a chemical reaction that takes place and it causes the particles in the compound to break
During a chemical reaction, energy gets used to break the existing bonds in order to create new bonds.
These structures are bonds. 100% positive.
The existing chemical bonds break and new bonds are created to give products.
During a chemical reaction, the bonds between the atoms of the reactants break, and new bonds form to make the products.
A chemical reaction can't break down an element, but it can break down a molecule.
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
In a chemical reaction, the bonds of the reactants are broken. The atoms will rearrange and new bonds will form.
In a chemical reaction, the bonds between the atoms of the reactants break, and new bonds are formed during the formation of the products.
do not break bonds
when atoms break their old links and form new links with other atoms it is called chemical reaction
This chemical reaction is called hydrolysis.
