+2 for Fe, +4 for C and -2 for each O
The oxidation number of Fe in FeCO3 is +2. This is because the overall charge of the carbonate ion (CO3^2-) is -2, so the iron (Fe) must have an oxidation state of +2 to balance the charge of the compound.
The oxidation number of C in FeCO3 is +4. This can be determined by assigning the oxidation number of +2 to Fe and -2 to each O atom, and then solving for C based on the overall charge of the compound.
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
The oxidation number of C in FeCO3 is +4. This can be determined by assigning the oxidation number of +2 to Fe and -2 to each O atom, and then solving for C based on the overall charge of the compound.
if iron has an oxidation state of +2 K2(CO3) + FeBr2 ---> KBr + FeCO3 if iron has an oxidation state of +3 3K2(CO3) + 2FeBr3 ----> 6KBr + Fe2(CO3)3
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.
