The chemical formula of an ionic compound that contains aluminium and chlorine is aluminium chloride - AlCl3.
Chlorine atoms, which are present as chloride ions.
The compound contains the two elements Potassium and chlorine it is an exothermic chemical reaction because it releases heat energy when formed.
Since aluminum is a chemical element it contains no other substances.
MgCl2 contains the elements magnesium and chlorine.
Cl2
The chemical formula of aluminum sulfate is Al2(SO4)3, consequently this compound contain aluminum, sulfur and oxygen.
Cl3
This compound is calcium chloride - CaCl2.
because it contains two or more chemical things on it. like salt is a compound because it contains sodium and chlorine.
Sodium chloride (NaCl) contain sodium and chlorine.
Chlorine atoms, which are present as chloride ions.
Aluminum chloride is not a metal. When a metal (Aluminum) is compounded with a nonmetal (Chloride) the resulting compound is no longer a metal.It is an example of an inorganic compound that "cracks" at mild temperature, reversibly changing from a polymer to a monomer.
The diatomic chemical formula of chlorine is Cl2.
Every chemical compound is unique and different from the ELEMENTS it contains
ClO4 is not a compound, it exists as ClO4-, which is a polyatomic ion called the perchlorate ion. Some positive ion such as potassium or ammonium must be present to balance the charge and form a compound.
The compound contains the two elements Potassium and chlorine it is an exothermic chemical reaction because it releases heat energy when formed.
Since aluminum is a chemical element it contains no other substances.
