A new molecule is formed after a chemical reaction.
Endothermic reactions require energy input in order to take place. This energy is needed to break the existing bonds in the reactants before new bonds can be formed in the products. Examples of endothermic reactions include baking, photosynthesis, and the reaction between citric acid and sodium bicarbonate in a baking soda volcano.
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.
Energy is required for evaporation to take place. This energy, in the form of heat, is needed to break the bonds between liquid molecules so they can escape into the air as gas.
yes its a non living thing its present in the cell but all chemial reactions take place here
When bonds break and new bonds form, a chemical reaction has taken place.

It is possible to break bonds between oxygen by supplying heat and this process takes place in all burning / oxidation reactions.

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.
When you see flames, it means that there is a chemical reaction taking place that involves the rapid oxidation of a material in the presence of heat, fuel, and oxygen. The release of energy in the form of heat and light is what we perceive as flames.
To purchase I bonds from Treasury Direct, you need to create an account on the Treasury Direct website, provide your personal information, link a bank account for funding, and then place an order for the I bonds through the online platform.
In order to have some fun. Or crack something to cheat, break in, or fix something.
