aluminum chloride, usually seen as AlCl3
The name for AlCl2 is aluminum chloride. Aluminum chloride is a compound composed of one aluminum atom and two chlorine atoms, resulting in a chemical formula of AlCl2. It is a white or pale yellow solid that is commonly used as a catalyst in organic chemistry reactions.
Although Aluminum Chloride (AlCl2) does have polar bonds, since there is a difference in electronegativity between the aluminum atom and chloride atom, the three dipoles cancel each other out, since there are no excessive electrons on the Aluminum. The Molecular and Electronic Geometry of AlCl2 are Trigonal Planar, so the bond angle will be 120 degrees. Long story short, the dipoles cancel each other out, causing the molecule as a whole to be non-polar.
The formula for magnesium sulphate is MgSO4.You have not specified any reaction, so there is no way to write the equation for it!See the Related Questions to the left for how to write a balanced chemical reaction.
Assuming a reactive metal and acid combination are used (that is, ignoring things like passivation layers, oxide shields, etc) then the general reaction in aqueous media is: For metals producing monovalent cations (eg Na, K, Li etc) n.M + HnA > n M+ + An- + n/2. H2 For metals producing divalent cations (eg Ca, Mg, Ba) M + 2/n.HnA > M++ + 2/n.An- + n.H2 So, basically, you get the metal salt + hydrogen
Al + 2HCl --> AlCl2 + H2

The chemical equation is Al2(SO4)3 + 3BaCl2 --> 2AlCl3 + 3BaSO4. (I corrected the formulas containing aluminum.)
An element that can form a chloride with a general formula of MCl2 is considered to have a +2 oxidation state, and an element that can form a chloride with a general formula of MCl3 is considered to have a +3 oxidation state. Some examples include iron, with FeCl2 and FeCl3, and aluminum, with AlCl2 and AlCl3.

Aluminium(III) chloride, or AlCl3 - aluminum only has access to its 0 and 3+ oxidation states.
