β 14y agoSubstance A is likely an element, as it cannot be broken down by a chemical change. Substance Z is likely a compound, as it can be broken down by a chemical change into simpler substances. From this information, it can be concluded that substances A and Z have different chemical compositions and properties.
Physical change because the molecules have not changed to form a new substance.
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
chemical
Compounds are broken down into elements by chemical change, where chemical bonds are broken and rearranged to form new substances. Physical changes do not alter the chemical composition of a substance.
A chemical change is a change in the composition or structure of a substance, resulting in the formation of new substances with different properties. This type of change is usually irreversible and involves the breaking and forming of chemical bonds.
No, it is a physical change as the identity of the substance remains the same. Broken glass is still glass.
Physical change because the molecules have not changed to form a new substance.
Hexane can be broken down by a chemical change because it can undergo reactions that change its chemical structure. These reactions can involve breaking and forming new chemical bonds, resulting in a different set of molecules compared to the original hexane compound. This is in contrast to physical changes, which do not alter the chemical composition of a substance.
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
chemical
The chemical properties of an object show what a chemical change did to that substance.
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
During a chemical change, the identity and composition of a substance are altered as new chemical bonds are formed or broken. This change is usually irreversible and produces a new substance with different chemical properties compared to the original materials. Examples include combustion, oxidation, and digestion.
chemical change is the change of one substance into another substance.
