Answer:
That oxidation number of chlorine is -1 while that of oxygen is -2
Explanation:
When it comes to manganese chloride to stabilize the chlorine Ion. Two manganese ions shall be required. Hence the formula for the compound becomes [tex]M_nCl_2[/tex] while the formula for manganese (iv) chloride will be [tex]M_nCl_4[/tex] similarly.
When oxygen and magnesium oxide is considered the Two ions of Manganese will satisfy to ions of oxygen. Which cancels and becomes [tex]M_nO[/tex] while for manganese (iv) oxide the formula becomes [tex]M_nO_2[/tex].
Answer:
1) Manganese(II)chloride :[tex]MnCl_{2}[/tex]
2) Manganese(IV)chloride :[tex]MnCl_{4}[/tex]
3) Manganese(II)oxide :[tex]MnO[/tex]
4) Manganese(IV)oxide :[tex]MnO_{2}[/tex]
Explanation:
It is given that:
Oxidation number of chlorine (Cl) = -1
Oxidation number of Oxygen (O) = -2
1) Manganese(II)chloride :
The oxidation number of manganese (Mn) is indicated by the roman numeral II = +2
Oxidation number of chlorine (Cl) = -1
Since the molecule is neutral the sum of charges on the cation (Mn) and anion (Cl) should be zero. This is possible only if one mole Mn combines with 2 moles Cl. Therefore, the chemical formula is [tex]MnCl_{2}[/tex]
2) Manganese(IV)chloride :
The oxidation number of manganese (Mn) is indicated by the roman numeral IV = +4
Oxidation number of chlorine (Cl) = -1
Since the molecule is neutral the sum of charges on the cation (Mn) and anion (Cl) should be zero. This is possible only if one mole Mn combines with 4 moles Cl. Therefore, the chemical formula is [tex]MnCl_{4}[/tex]
3) Manganese(II)oxide :
The oxidation number of manganese (Mn) is indicated by the roman numeral II = +2
Oxidation number of Oxygen (O) = -2
Since the molecule is neutral the sum of charges on the cation (Mn) and anion (O) should be zero. This is possible only if one mole Mn combines with 1 mole O. Therefore, the chemical formula is [tex]MnO[/tex]
4) Manganese(IV)oxide :
The oxidation number of manganese (Mn) is indicated by the roman numeral IV = +4
Oxidation number of Oxygen (O) = -2
Since the molecule is neutral the sum of charges on the cation (Mn) and anion (O) should be zero. This is possible only if one mole Mn combines with 2 moles O. Therefore, the chemical formula is [tex]MnO_{2}[/tex]
