How is a chemical bond usually broken?
Chemical bonds are both formed and broken during chemical reactions. For example, bonds are formed and broken in the synthesis reaction 2H2 + O2 = 2H2O. The bonds in both diatomic oxygen and hydrogen are broken, forming new bonds to form a water molecule.
How energy is made available by chemical reaction?
in chemical reactions, energy is absorbed or released when chemical bonds are broken and new ones are formed.
How are chemical bonds changed in reactions?
In any chemical reaction, at least one chemical bond is either broken or formed. However, particularly in organic chemical reactions, many bonds may remain intact from the reactants to the products, provided that at least one is broken or formed.
How are molecules built and broke down?
Molecules are formed by synthesis from elements; molecules are broken by chemical reactions.
When most chemical reactions take place some in the reactants must be broken a process that requires energy?
Catalysts
Are chemical reactions part of covalent bonding?
Covalent bonds can be formed because of chemical reactions.

What reaction is a process in which a covalent or ionic bond is broken or formed?
chemical reaction

In a chemical reaction bonds are broken or?
Chemical reactions can be either endothermic (that is, where bonds broken) or exothermic (i.e. where bonds are formed). The former requires thermal energy input; the latter releases heat energy as bonds are formed.
What happens to the bonds between atoms in a substance that undergoes a chemical reaction?
At least one electron from one of the atoms is transferred from an orbital where it occurs in a single atom to either an orbital in one of the other atoms, forming an ionic bond between the two atoms, or to a different orbital that can exist only under the influence of two atoms, forming a covalent bond between the two atoms. In the latter instance, but not the former, the atoms bonded can be atoms of the same element.

What is a substance formed in a chemical reactions?
a substance that is formed in a chemical reaction is called a product=)After a chemical reaction, new chemicals are formed. For an example:-NaOH + HCl = NaCl + HOH(H2O)Chemical substances are formed in chemical reactions.
What happens in a chemical reactions?
the change in the nuclei of the atoms.
What is name for a substance formed in a chemical reaction?
Products are formed from chemical reactions.
