Why is enthalpy of chemisorption higher than physisorption?
Chemical bonds in chemisorption are much stronger.
What is the ability of a substance to combine chemically with another substance called?
The ability to combine chemically through the formation of chemical bonds with another substance is a chemical property.
The strength of the chemical bonds holding the atoms together affects which of the following.?
For example are affected the melting point, boiling point, density, reactivity, etc.
What chemical bond possess low latent heat of fusion?
Latent heat of fusion (or enthalpy of fusion) is a characteristic of a substance, rather than a chemical bond. If you mean enthalpy of reaction then the lowest absolute values are for the bonds in H2, F2, and Cl2 as gases, which are zero. One low (and negative) value is for cuprous sulphate. Please see the link.
Where was the energy that is released in an endothermic reaction originally stored?
Energy is released during an exothermic reaction. The energy released was enthalpy. This includes quantities such as the attraction between molecules, the lattice energy, the chemical bonds... depends on the reaction.An endothermic reaction absorbs energy in the enthalpy of solution. It comes from the surroundings.

What is Energy stored in chemical bonds of molecules.?
Energy stored in chemical bonds of molecules is referred to as chemical energy.This is known as 'enthalpy'.The type of energy that is stored in a molecules bonds is potential energy. This energy can also be called bond energy.It is important to know the different kinds of energy. Potential energy is the energy that is stored in chemical bonds.
Name two properties of minerals that depend on chemical bonds?
Examples: chemical reactivity, toxicity, flammability, stability.
What is stored molecular energy called?
Energy stored in chemical bonds of molecules is referred to as chemical energy.This is known as 'enthalpy'.The type of energy that is stored in a molecules bonds is potential energy. This energy can also be called bond energy.It is important to know the different kinds of energy. Potential energy is the energy that is stored in chemical bonds.

What is standard enthalpy change of atomization?
the breaking down of elements into atoms. it is the energy required when 1 mole of a substance completely decomposes into its gaseous atoms i.e endothermic reaction, delta H is +ve meaning breaking bonds

What happens to chemical bonds when new compounds are formed in a chemical reaction?
the bonds get larger and more bonds are created
What substance helps make or break a chemical bond?
A chemical reaction involves the making and breaking of strong chemical bonds. Explanation: Chemical reactions are characterized by the formation of new substances, and the making and breaking of strong chemical bonds. In practice it is usually fairly easy to discriminate between a chemical change, new substances formed, and a phase change, where bonds may have been broken but no new substances formed. Examples of chemical reactivity where chemical bonds are manifestly formed include hydrocarbon combustion, the which drives our industrial society, and in which C − C and C − H bonds are clearly broken, and O − H and C O bonds are clearly formed in the products.
