You probably mean H2SO4, where H +1; S +6;O-2.
H2SiO4 does not exist. If it did the oxidation numbers of the constituent elements would be H +1; Si +6; O -2. The compound silicic acid is H4SiO4 (not isolatable) with H +1, Si +4 and O -2.
H: +1
s: +6
o: -2
+1/2
oxidation number of I is -1. oxidation number of F is +1.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
Zn has oxidation number +2; S has oxidation number -2
Potassium's oxidation number is +1. Chromium's oxidation number is +6. Oxygen's oxidation number is -2.
oxidation number of I is -1. oxidation number of F is +1.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
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.
The oxidation number for silicon dioxide (sand) is typically +4 for the silicon atom and -2 for the oxygen atoms. This results in an overall neutral charge for the compound.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
Potassium's oxidation number is +1. Chromium's oxidation number is +6. Oxygen's oxidation number is -2.
The oxidation number of lithium metal is +1. As an alkali metal, lithium tends to lose its outermost electron to achieve a stable electron configuration.
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
The oxidation number for Kr is 0. As a noble gas, krypton does not readily form compounds and exists in its elemental form with a full outer shell of electrons.
The oxidation number of Fe in FeO (iron oxide) is +2. This is because oxygen typically has an oxidation number of -2, and in a neutral compound like FeO, the oxidation numbers must balance out to zero.
