energy must be added
Solids must be dissolved
During a chemical change, chemical bonds are broken and reformed to produce new substances.
A new molecule is formed after a chemical reaction.
Energy is the key for any reaction to take place. To break the bonds of a substance, a fixed amount of energy is required which is called bond energy. For some substances the bond energy is low and they do not require external energy and start reaction on their on there own whereas for some substances we have to provide external energy for the reaction to take place.
Chemical reactions are driven by the amount of energy used to break the bonds in the reactants ( the activation energy) and the energy released by making new bonds in the products. The stronger the forces holding together the molecules of products, the more readily the reaction takes place. The difference between the energy produced in making the bonds and breaking the bonds is called ENTHALPY. The reaction can also be driven if the products have a greater degree of disorder (ENTROPY) than the reactants.
yes its a non living thing its present in the cell but all chemial reactions take place here
It is used to break hydrogen bonds so that water molecules can escape the liquid state.
When bonds break and new bonds form, a chemical reaction has taken place.
A new molecule is formed after a chemical reaction.
It is possible to break bonds between oxygen by supplying heat and this process takes place in all burning / oxidation reactions.

Hydrogen bonds break and two double stranded DNA molecules are synthesized.
a simple kind of pipette is made up of plastic or glass with a small containing ,is used to transfer chemial from one place to another
In order to have some fun. Or crack something to cheat, break in, or fix something.
The spark provides enough energy to break the bonds of reacting molecules and get the reaction started.
