Chemical reactions can be either endothermic (that is, where bonds broken) or exothermic (i.e. where bonds are formed). The former requires thermal energy input; the latter releases heat energy as bonds are formed.

What is a formed or broken apart during a chemical reaction?
chemical bond
Is heating copper sulfate pentahydrate a chemical reaction?
No, it is not a chemical reaction. The added heat only drives the water molecules out of the crystal structure. No bonds are made or broken. Actually, it is a chemical change, because there are bonds between the water and CuSO4. by heating, these bonds are broken, there is a color change not coming from the reactant.
A chemical reaction in which bonds are broken is usually associated with blank?
A chemical reaction in which bonds are broken is usually associated with the release of energy. Stable bonds are responsible for releasing energy as they are formed.
What does chemical reaction have to do with making and breaking bonds?
Bonds in the reactants are broken, and bonds in the product are formed.
What initiates chemical reactions by breaking bonds in the reactants?
That process is called a chemical reaction.
What is broken before a chemical reaction take place?
They are called chemical bonds, or just bonds.
What is formed or broken in a chemical reaction?
Some bonds between atoms are broken and new bonds are formed.
They are broken before a chemical reaction takes place?
Chemical Bonds
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 chemical reactions the type of chemicals bonds being broken are?
This is a chemical reaction.
What is it called when chemical bonds are broken rearanged and reformed?
A chemical reaction occur.
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 always happens to the atoms within molecules undergoing a chemical reaction?
In a chemical reaction sometimes old bonds are broken and new bonds are formed.
What is a chemical reaction that harvests energy when chemical bonds are broken?
It always takes energy to break chemical bonds. Similarly, energy is released when bonds are formed. When the new bonds formed are weaker than the old ones broken, the reaction consumes energy and is called endothermic.
When old chemical bonds are broken and new ones are formed this is called?
A chemical reaction.
When old chemical bonds are broken and new ones formed this is called what?
A chemical reaction.
