Predict the formula of a compound formed by aluminium and sulphur.a)Al...
The compound formed by aluminium and sulphur is aluminium sulphide (Al2S3).
Explanation:
1. Determine the oxidation states:
Aluminium typically has an oxidation state of +3 (Al3+), while sulphur typically has an oxidation state of -2 (S2-).
2. Determine the number of atoms needed to balance the charges:
Since the oxidation state of aluminium is +3 and the oxidation state of sulphur is -2, we need to balance these charges. This can be done by combining two aluminium ions with three sulphur ions.
3. Write the formula:
The formula for the compound formed by aluminium and sulphur is Al2S3. This indicates that two aluminium ions combine with three sulphur ions to form the compound.
4. Check the formula for consistency:
To confirm that the formula is consistent, we can determine the total charge of the compound. The charge of two aluminium ions (+6) should balance the charge of three sulphur ions (-6).
Summary:
The compound formed by aluminium and sulphur is aluminium sulphide (Al2S3). This formula indicates that two aluminium ions combine with three sulphur ions to form the compound. The oxidation state of aluminium is +3, and the oxidation state of sulphur is -2, so the charges are balanced in the compound.
