This is a levis acid.Al Shows the +3 as theoxidation number.
To form aluminum fluoride, each aluminum atom donates three electrons to three fluorine atoms. The oxidation number of aluminum ions is +3. Fluoride ions have -1 as oxidation number.
-1 for each F, +3 for Al.
oxidation number of I is -1. oxidation number of F is +1.
Formula: AlF3
Zn has oxidation number +2; S has oxidation number -2
The oxidation number for H is +1, and the oxidation number for O is -1.
-1 for each F, +3 for Al.
oxidation number of I is -1. oxidation number of F is +1.
Formula: AlF3
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
Al(FlO3)3. Al has a charge of +3 and FlO3 has a charge of -1 so 3 fluorate ions are needed for every Al ion to balance the charge of the compound. ***extra--if you didn't know what fluorate was.... A well known ion, ClO3 (the chlorate ion), has a charge of -1. Fl is in the same group as Cl so the fluorate ion will have the same number of oxygens and the same charge as ClO3.
Zn has oxidation number +2; S has oxidation number -2
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
The oxidation number for H is +1, and the oxidation number for O is -1.
Oxidation number of Si is +4.Oxidation number of O is -2.
Carbon atoms oxidation number is +2.Hydrogen's oxidation number is +1.Oxygen's oxidation number is -2.
Potassium's oxidation number is +1. Chromium's oxidation number is +6. Oxygen's oxidation number is -2.
Oxidation number of Li is +1. Oxidation number of oxygen is -2.
