Firstly, I will begin by stating that for every chemical reaction there is an activation energy. This means, a reaction requires energy to undergo; however, this energy is most often take from the environment, such as in the form of heat. In some cases, the reactants require a great deal of energy and are thus supported by energy providers like ATP or reaction facilitators such as enzymes. In the area of bonds, many reactions entail a change in the bonds contained in the molecule produced. For example, when glucose is broken down to produce ATP, it's bonds are removed and its atoms placed onto new molecules. Thus, for this reaction and most others, the bonds are broken and replaced. Moreover, in the production of disaccharides, only one bond is broken on each monosaccharide, by way of a dehydration reaction. The leftover ends of each molecule, wanting to bond and this achieve a less reactive state, then attach. Thus, bonds are broken and replaced here as well. As such, it can be concluded that in a chemical reaction, the reactants' bonds are changed, not always totally, but in the removal of done bonds and addition of others.

MaxineReactants must come into close proximity to each other for bonds to form. Additionally, reactants must possess enough energy to overcome the activation energy barrier for bond formation. The alignment of atoms or molecules in the correct orientation is also crucial for successful bond formation.

What is energy is a minimum amount of energy required for substances to react?
Activation energy is the minimum amount of energy required for substances to react. It is necessary to break the existing bonds in the reactants before new bonds can form in the products.
What structures break in reactants?
In a chemical reaction, bonds between atoms are broken in reactant molecules. These bonds can be covalent or ionic bonds, which hold the atoms together in the reactant molecules. When these bonds are broken, new bonds can form between atoms, leading to the formation of products.
Why do Magnesium and Hydrochloric acid have an exothermic reaction?
When magnesium reacts with hydrochloric acid, it forms magnesium chloride and hydrogen gas. This reaction is exothermic because it releases energy in the form of heat. The formation of new chemical bonds in the products releases more energy than is required to break the bonds in the reactants, resulting in the release of heat.
In exothermic reactions the energy required to break the bonds in the reactants is greater than the energy released as the products form?
In exothermic reactions, the energy needed to break the bonds in the reactants is higher than the energy released when the products are formed. As a result, the excess energy is released to the surroundings in the form of heat. This results in a net release of energy during the reaction.
Look at the chemical reaction How does the chemical energy of the reactants compare to the chemical energy of the products?
In a chemical reaction, the chemical energy of the reactants is typically higher than that of the products. This is because energy is needed to break the bonds in the reactants to form new bonds in the products. The difference between the energy of the reactants and the products is often released or absorbed as heat.
