Neither. It defines the substance but does not characterize it.
The chemical properties are the same. The physical properties are not.
Formula: X.7H2OX is a compound
For correction purposes the correct way to write this is H2O and it is the chemical formula for water.
If the steam is being produced by boiling water the physical property is gas and the chemical properties are H2O.
H2O is the chemical formula of water.
H20 has both chemical and physical properties.
The chemical properties are the same. The physical properties are not.
H2O is not a property, it is a substance with physical and chemical properties.
No. Ice is solid H2O, which is a substance, not a property. It has physical and chemical properties.
Physical change. The chemical formula of the steam still remains as H2O.
H2O is the chemical formula for water.
It's a physical change because the substance is the same before and after only changing form. In other words, water's chemical formula is H2O and ice's chemical formula is also H2O, so they are the same substance. Therefore it is a physical change.
H2O is the chemical formula of water.
a physical change, it's chemical formula is still H2O
It isn't. The melting of ice is a phase change, which is a physical change because the chemical composition of the water does not change.
Formula: X.7H2OX is a compound
When a physical change occurs, the compound stays the same. For example, if you boil water, the chemical formula still remains H2O and is a physical change. However, if you were to change the chemical formula, it would be a chemical change. If H2O were split into H2 and O2 gas, it would be a chemical change.
