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.

Definition of activation energy
The minimum extra amount of energy absorbed by the reactant molecule so that their energy becomes equal to threshold value is called activation energy.
This activation energy not only used for break preexisting bond it's also used to create new bonds in products.

What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
What new substances are formed during a chemical reaction?
The new substances formed during a chemical reaction are called Products.
What is the scientific word for a gas given off during a chemical reaction?
A reaction that emmits heat is called an exothermic reaction .
Why is a phase change not a chemical reaction?
Because chemical bonds are not formed or broken by a phase change.
Does energy decrease or increase during a chemical reaction?
Energy is only made not taken away. But during a chemical reaction, it depends on what kind of chemicals you put in there.
What happens to energy during a chemical reaction?
During a chemical reaction, energy gets used to break the existing bonds in order to create new bonds.
When new substances are formed from existing substances during a chemical reaction they are known as?
Products.
What happens to chemical bonds in a molecule during a chemical reaction?
The existing chemical bonds break and new bonds are created to give products.
What happens chemical bonds during a chemical reaction?
Some or all of the existing chemical bonds in the reactants are broken and new chemical bonds are formed in the products.
What happens to the atoms of an object or a substance during a chemical reaction?
The atoms involved in a chemical reaction have their bonds broken, new bonds formed, or existing bonds rearranged depending on the reaction type.
What is always formed during a chemical reaction?
a chemical reaction always converts reactants to products. Products are always formed otherwise it's not considered a chemical reaction.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
Is endothermic a chemical reaction?
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What happens to the bonds of the products during a chemical 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.
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
