How is beryllium turned into emerald?
Emerald is a form of the mineral beryl that gets its green color from trace amounts of chromium and sometimes vanadium. These impurities give the beryl crystal its vibrant green hue, transforming it into an emerald. Beryllium itself does not turn into emerald, but it is part of the chemical composition of beryl, which is the mineral that emerald is made from.
When water evaporates its chemical composition?
The chemical composition remain unchanged.

Does melting ice changes the chemical composition of water?
The chemical composition of water remain unchanged.
Why is emerald a sillacate mineral?
Emerald is classified as a silicate mineral because its chemical structure contains silicon and oxygen, which are the primary components of silicate minerals. Specifically, emerald is a variety of beryl, with the chemical formula Be₃Al₂(SiO₃)₆, indicating that it includes the silicate tetrahedra (SiO₄) as part of its crystalline framework. This silicate structure contributes to its unique properties, such as its distinctive green color, which is caused by trace amounts of chromium and vanadium. Thus, emerald's classification as a silicate is rooted in its composition and crystal structure.

What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
