The energy needed to break an existing chemical bond is called activation energy, also written as Ea
Activation energy can be decreased with the help of a catalyst, which helps to facilitate chemical reactions.
The substances you have at the beginning of a chemical reaction are called the reactants.
Energy is often absorbed during a decomposition reaction because the reactant breaks down into smaller molecules or atoms. This process typically requires energy input to break the existing chemical bonds.
A reaction that emmits heat is called an exothermic reaction .
A chain reaction typically involves three steps: initiation, propagation, and termination. During initiation, the reaction is triggered by an initial event. In propagation, products from the initial reaction continue to react, creating more products. Termination occurs when the reaction eventually stops due to the depletion of reactants or other factors.
During a chemical reaction, new substances called products are formed as a result of the rearrangement of atoms in the reactants. These products have different chemical properties from the original reactants, and the reaction may involve the breaking and forming of chemical bonds.
Products.
The existing chemical bonds break and new bonds are created to give products.
Some or all of the existing chemical bonds in the reactants are broken and new chemical bonds are formed in the products.
The atoms involved in a chemical reaction have their bonds broken, new bonds formed, or existing bonds rearranged depending on the reaction type.
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
Chemical bonds are formed or broken apart during a chemical reaction. Bonds between atoms are either created or destroyed, resulting in the formation of new compounds or the breakdown of existing ones.
a chemical reaction always converts reactants to products. Products are always formed otherwise it's not considered a chemical reaction.
A catalyst undergoes no chemical change during a chemical reaction.
The substances you have at the beginning of a chemical reaction are called the reactants.
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
This chemical reaction is called dehydration.
