Is the change between sodium and chlorine a physical change or chemical?
chemical
Is dissolving sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
When sodium melts is it a physical or chemical change?
When sodium melts, it undergoes a physical change. This is because the change in state from solid to liquid does not alter the chemical composition of the sodium itself. It remains as sodium in both the solid and liquid states.
When a pellet of sodium is sliced in half is that a physical or chemical change?
Slicing a pellet of sodium in half is a physical change because it does not alter the chemical composition of the sodium. The sodium is still sodium before and after slicing, just in smaller pieces.
When sodium carbonate is crushed it is physical or chemical change?
It is only a physical change.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
if a pellet of sodium is sliced in half is it a chemical or physical change?
It is a physical change as
Is dissolving sodium chloride a chemical or physical change?
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
Is a pellet of sodium is sliced in two a physical change or a chemical change?
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
A pellet of sodium is sliced into two. Physical or chemical change?
It's a physical change
