When many were taught chemistry in the 1970s this was called a double decomposition reaction. It is now called a salt metathesis reaction and also double displacement reaction. There are examples and more information at the related link.
The reaction between SO42- and Ba2+ forms BaSO4. The chemical formula is BaSO4.
The balanced chemical equation for this reaction is: 2AlBr3 + 3Cl2 → 2AlCl3 + 3Br2.
In a chemical equation, the compounds represented by the letter "a" can vary depending on the specific reaction being described. It is a placeholder that can be substituted for the actual compound formula when balancing the equation. The coefficient of "a" indicates the number of moles of that compound involved in the reaction.
