Which property of physical changes explains why matter is conserved in a physical change? The arrangements of particles do not change, and the bonds between atoms do not break. Mass, not energy changes in a physical change.
Energy and mass change in a physical change.
The bonds between atoms do not break, it's only the arrangement that changes.

Mass is the amount of matter in an object, and weight is the downward pull on an object due to gravity. Which property of physical changes explains why matter is conserved in a physical change? The bonds between atoms do not break; it is only the arrangement that changes.

hope I helped! :)

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
