What makes up a chemical change?
A chemical change involves the formation of new substances with different chemical properties than the original ones. This can involve the breaking and forming of chemical bonds, resulting in a change in the composition and structure of molecules. Evidence of a chemical change includes the release or absorption of energy, color change, formation of a precipitate, or production of gas.
Does breaking an ice cube change the identity of an ice cube?
Breaking an ice cube into smaller pieces does not change its identity as ice; it is still made of the same substance, which is water in its solid state. The physical arrangement of the ice cube has changed, but its chemical composition remains the same.
Can you bend a pencil without breaking it?
No, a pencil cannot be bent without breaking it because it is made of a rigid material like wood or plastic. Attempting to bend it will likely result in it snapping or fracturing.
What substance can only be broken down by chemical change?
A substance that can only be broken down by chemical change is a compound. Compounds are made up of different elements chemically bonded together, and breaking these bonds requires a chemical reaction. Physical changes, such as melting or dissolving, cannot break compounds down into their individual elements.

Does breaking a mirror cause a change of chemical properties?
Breaking a mirror does not cause a change in the chemical properties of the mirror itself. The act of breaking the mirror may result in physical changes, such as the mirror's fragments having sharp edges, but the chemical composition of the mirror remains the same. Mirrors are typically made of a layer of reflective material, like silver or aluminum, which is deposited on the glass surface, and breaking the mirror does not alter this composition.
