During a chemical change, the particles of matter rearrange to form new substances with different chemical properties. Bonds between atoms break and reform, resulting in the creation of products that are different from the original reactants. The total number of atoms remains the same, as a chemical change does not create or destroy atoms.

What happens to the particles when a physical or chemical change occurs?
As a substance goes from the solid to liquid to gas state, the particles in it are getting farther and farther apart, because they are obtaining more energy, causing them to move around faster, collide more, and move apart. As a substance goes from the gas to liquid to solid state, the particles in it are getting closer and closer, because they are losing energy which causes them to slow down and get pushed tighter together.
What happens to energy when matter undergoes chemical or physical change?
During a chemical or physical change, the energy of matter can either be absorbed or released. For example, in chemical reactions, energy is exchanged in the form of heat or light as chemical bonds are broken or formed. In physical changes, such as melting or boiling, energy is used to break intermolecular forces between particles.
What happens to chemical bonds during chemical change?
During a chemical change, chemical bonds are broken between atoms in the reactants and new bonds are formed to create products. Energy is either released or absorbed during bond breaking and forming processes. The types and strengths of the bonds determine the overall energy change of the chemical reaction.
What happens to energy during a chemical change?
when a chemical change occurs, chemical bonds are broken up
What happens when a pure substance undergoes a chemical change?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
What happens to chemical change during a chemical change?
when a chemical change occurs, chemical bonds are broken up
What happens to matter and the particles of an object during physical change?
During a physical change, the matter remains the same, but the arrangement and position of the particles within the object may change. This can involve processes like melting, freezing, or evaporating, where the particles gain or lose energy to shift from one state to another while still maintaining their identity.
What happens at the atomic level during chemical change?
Atoms change the position from a molecule to another.

What indicates a chemical change happens while cooking?
The chemical composition of foods is changed during cooking.
What happens to mass during chemical and physical change?
it stays da same
What happens to matter during chemical change?
The chemical nature of the matter is changed; new compounds with new chemical formulas are formed.
What happens to mass during a chemical change?
Mass is conserved. This means it remains constant.

What happens to the bonds between atoms during a chemical change?
They break and new bonds are formed
What undergo no chemical change during a chemical change?
Catalysts doesn't undergo a chemical change during a chemical reaction.
