The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. This is because each chlorine atom has an oxidation number of -1, and there are three chlorine atoms bonded to the aluminum atom, resulting in a total charge of -3 for the chlorine atoms. For the compound to be neutral, the aluminum atom must have an oxidation number of +3.
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. Aluminum typically has an oxidation number of +3 when it forms ionic compounds.
The oxidation number of aluminum in aluminum bromide is +3. In this compound, aluminum has transferred three electrons to bromine to form the ionic bond, resulting in an oxidation state of +3 for aluminum.
The oxidation number of nitrogen in the ammonium ion NH4+ is -3, and the oxidation number of hydrogen is +1. In ammonium chloride NH4Cl, the net charge on NH4 is +1 because the chloride ion Cl- has an oxidation number of -1.
The oxidation number for iron in ferric chloride (FeCl3) is +3. Chlorine has an oxidation number of -1, and since there are three chlorine atoms in ferric chloride, the overall charge must be balanced by the iron atom having an oxidation number of +3.
The oxidation number of aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. Aluminum typically has an oxidation number of +3 when it forms ionic compounds.
The oxidation number of Al is +3.
The oxidation number of aluminum in aluminum bromide is +3. In this compound, aluminum has transferred three electrons to bromine to form the ionic bond, resulting in an oxidation state of +3 for aluminum.
The oxidation number of nitrogen in the ammonium ion NH4+ is -3, and the oxidation number of hydrogen is +1. In ammonium chloride NH4Cl, the net charge on NH4 is +1 because the chloride ion Cl- has an oxidation number of -1.
In aluminum oxide (Al₂O₃), the oxidation number of aluminum (Al) is +3. This is determined by considering that oxygen typically has an oxidation number of -2. Since there are three oxygen atoms contributing a total of -6, the two aluminum atoms must have a combined oxidation number of +6, leading to an individual oxidation state of +3 for each aluminum atom.
The oxidation number for iron in ferric chloride (FeCl3) is +3. Chlorine has an oxidation number of -1, and since there are three chlorine atoms in ferric chloride, the overall charge must be balanced by the iron atom having an oxidation number of +3.
The oxidation number of aluminum (Al) in Al2S3 is +3, while the oxidation number of sulfur (S) is -2. Each aluminum atom has an oxidation number of +3, and each sulfur atom has an oxidation number of -2 in order to balance the charge in the compound.
+3 for each Al; +4 for each C; -2 for each O
In the compound Al₂O₃, aluminum has an oxidation number of +3, and oxygen has an oxidation number of -2. This gives a total charge of zero for the compound, as it should be electrically neutral.
In the reaction of aluminum with oxygen to form aluminum oxide (Al + O2 -> Al2O3), the oxidation number of aluminum changes from 0 to +3, while the oxidation number of oxygen changes from 0 to -2. This indicates that aluminum is undergoing oxidation, while oxygen is undergoing reduction in the reaction.
Chlorine has an oxidation number of +1 in compounds with metals such as sodium chloride (NaCl) or potassium chloride (KCl).
Aluminum has only oxidation numbers.They are zero and +3.
