Grapes are examples of chemical bonds because of the way they all stick together close. Just like a molecule (which is what atoms are once they bond to two or more).
Examples: ionic, covalent, metallic bonds.
Grapes is a chemical change because refrigerator.
Chemical energy is stored in the chemical bonds of molecules. When these bonds are broken through chemical reactions, the energy stored in them is released in the form of heat or light. Examples of chemical energy sources include food, gasoline, and batteries.
Sound energy, gravitational potential energy, and mechanical energy are non-examples of chemical energy. Chemical energy is specifically related to the potential energy stored in chemical bonds.
Chemical energy is contained in the bonds between atoms within molecules. When these bonds are broken or rearranged during a chemical reaction, energy is released or absorbed. Examples include the energy stored in food molecules like glucose and in fossil fuels like gasoline.
An example of an organism using weak chemical bonds is the binding of hemoglobin to oxygen in red blood cells. Hemoglobin contains iron atoms which form weak bonds with oxygen molecules, allowing for the transport of oxygen in the bloodstream. Another example is the formation of hydrogen bonds in the structure of DNA, which are important for maintaining the double helix shape.

Potential chemical energy is stored in chemical bonds.
The main types of chemical bonds are ionic bonds, covalent bonds, and metallic bonds. Ionic bonds form between a metal and a nonmetal through the transfer of electrons. Covalent bonds occur when atoms share electrons, typically between two nonmetals. Metallic bonds are found in metals and involve a sea of delocalized electrons surrounding positively charged metal cations.
This change is known as a chemical reaction, where the chemical bonds between atoms are broken and new bonds are formed to produce different substances with distinct properties. Examples include combustion, oxidation, and neutralization reactions.
In the chemical bonds of its monomers.
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
