What happens to the bonds between atoms in a substance that undergoes a chemical reaction?
At least one electron from one of the atoms is transferred from an orbital where it occurs in a single atom to either an orbital in one of the other atoms, forming an ionic bond between the two atoms, or to a different orbital that can exist only under the influence of two atoms, forming a covalent bond between the two atoms. In the latter instance, but not the former, the atoms bonded can be atoms of the same element.

Difference between a reactant and product?
A reactant is a substance that undergoes a chemical reaction, while a product is a substance that is formed as a result of that reaction. Reactants are consumed during the reaction, while products are the end result of the reaction.
What type of reaction is it when iron combines with oxygen to form a more complex substance?
The reaction between iron and oxygen to form a more complex substance is a chemical reaction known as oxidation. In this reaction, iron undergoes oxidation, gaining oxygen atoms to form iron oxide.
What is the difference between an oxidizing agent and a fuel?
An oxidizing agent is a substance that can accept electrons and cause other substances to lose electrons in a chemical reaction. A fuel is a substance that undergoes combustion to produce energy. In a chemical reaction, the oxidizing agent facilitates the combustion of the fuel by accepting electrons from it.
What is the burning of substance called?
Burning is an oxidation reaction - a reaction with oxygen.
Is a glow stick chemical change?
Yes, the glow stick undergoes a chemical change when it is activated. The chemical reaction between the components inside the stick creates the light emission.
Difference between a reactant and product?
A reactant is a substance that undergoes a chemical reaction, while a product is a substance that is formed as a result of that reaction. Reactants are consumed during the reaction, while products are the end result of the reaction.
Is cornstarch mixed with vinegar a chemical reaction?
Yes, when cornstarch is mixed with vinegar, it undergoes a chemical reaction. The reaction between the two creates a substance known as a suspension, where the cornstarch particles are dispersed in the vinegar, resulting in a thickened mixture.
What type of reaction is it when iron combines with oxygen to form a more complex substance?
The reaction between iron and oxygen to form a more complex substance is a chemical reaction known as oxidation. In this reaction, iron undergoes oxidation, gaining oxygen atoms to form iron oxide.
What do scientist call a substance that forms during a chemical reaction?
Scientists call a substance that forms during a chemical reaction a product. This product is the result of the chemical reaction between the reactants.
What is the difference between a catalyst and an inhibitor?
Catalyst: a substance which promote and help a chemical reaction. Inhibitor: a substance which greatly reduces the rate of a chemical reaction.
What process happens when a substance undergoes a chemical change?
During a chemical change, the substance's chemical composition is altered, resulting in the formation of new substances with different properties. Bonds between atoms are broken and rearranged to form new molecules. This process is typically accompanied by the release or absorption of energy.
What is the substance formed as a result of a chemical reaction called?
The substance formed as a result of a chemical reaction is called a product. It is the result of the reaction between the reactants, which undergo a chemical transformation to form one or more products.
How can we classify the reaction between iron and oxygen?
The reaction between iron and oxygen can be classified as a chemical reaction where iron undergoes oxidation to form iron oxide. This process is known as rusting.
Explain what a chemical change is?
A chemical change is when a substance undergoes a transformation that results in the formation of one or more new substances with different chemical properties. This typically involves the breaking and forming of chemical bonds between atoms. Examples of chemical changes include rusting of iron and burning of wood.
What is the difference between an oxidizing agent and a fuel?
An oxidizing agent is a substance that can accept electrons and cause other substances to lose electrons in a chemical reaction. A fuel is a substance that undergoes combustion to produce energy. In a chemical reaction, the oxidizing agent facilitates the combustion of the fuel by accepting electrons from it.
What is the burning of substance called?
Burning is an oxidation reaction - a reaction with oxygen.
Where in a substance is chemical energy stored?
Chemical energy is stored in the bonds between atoms and molecules within a substance. When these bonds are broken through a chemical reaction, the stored energy is released.
