This is a VERY broad question, but the very basics is that it requires the input of energy in some form.
When bonds break and new bonds form, a chemical reaction has taken place.
Heat can sometimes break the chemical bonds of atoms.
the two bonds that must break is the adenine and chromosome
Bonds break in to reactants
It takes energy to break a bond. then the atoms rearrange and can form new bonds releasing energy.
Covalent bonds are the easiest to break, since they are the easiest to make. But no substance is made when bonds break.
Bonds can break under various conditions, such as heating, chemical reactions, or electromagnetic radiation. When bonds break, atoms or molecules are released from each other, leading to the formation of new compounds or species. The specific bonds that break depend on the nature of the substances involved and the energy input required for bond dissociation.
When water evaporates, it is the hydrogen bonds between water molecules that break, not the covalent bonds within each water molecule. The hydrogen bonds are weaker intermolecular forces that hold water molecules together. Breaking these bonds allows the water molecules to escape as vapor.
2H2 + O2 + 2H2O 2H-H + O=O = 2H-O-H..not shaped like this !! The bonds in the reactants break and the bonds in the products form. The bonds in the H2 and O2 break and the bonds in the water form.
One can break disulfide bonds effectively by using reducing agents such as dithiothreitol (DTT) or beta-mercaptoethanol. These agents break the sulfur-sulfur bonds in the disulfide bonds, allowing the protein or molecule to unfold or denature.
Yes you can break the bonds between atoms and after they are broken they can also reform themselfs.
A new molecule is formed after a chemical reaction.
