Al3+ + S2- ------------> Al2S3
Al2S3 is the correct formula for aluminum sulfide.
Al2S3====
Al3+ and P3- form AlP Aluminum phosphide
Al3+ and CH3COO−
AlCl3 --> Al3+ + 3 Cl-
aluminum cloride
Al2S3 is the correct formula for aluminum sulfide.
Al2S3====
Al3+ and Br- together make, AlBr3
Al3+ and P3- form AlP Aluminum phosphide
AlI3 The algebraic sum of the oxidation numbers of the combining atoms must equal zero. The oxidation state of Al3+ is balanced by three ions of iodine (I-).
AL3 plus and O2 negative will form Aluminum Oxide. It has many names such as corundum and alumina. It is an amphoteric oxide.
Al3+ and CH3COO−
Al3+
Al2O3, aluminium oxide. Remember the numbers must be subscripts.
Al2S3 is the empirical formula
Al2O3
