Introduction: In science there are two kinds of properties: chemical and physical. A physical property is something which is observed using the five senses, in reference to the state of matter, density, melting/freezing point, and boiling point. This is also referred to as qualitative. The other kind of property is chemical. This is a reference to the chemical identity. Examples of these properties are solubility, flammability, acidity, toxicity, …show more content…
This was proven to be affirmative. A piece of magnesium ribbon was placed into a graduated cylinder with Copper (II) Sulfate and started reacting right away. The chemical substance started tearing at the metal, causing copper to be reduced into copper atoms which were then precipitated down. Then the magnesium ribbon was oxidized and underwent the aqueous phase, which caused copper to be eliminated effectively. Magnesium sulfate collides and copper separates, experiencing a chemical
