The oxidation number is +2 for Ni.
in CO32- ion
O.S. of Carbon = +4
C is +4, each oxygen is -2
There is no compound by the name nickel(I) carbonate. Nickel(II) carbonate is however NiCO3
Using the periodic table of elements you can find the oxidation number of NaHCO3. Na has a charge of +1 so it's oxidation number is +1. H has a charge of +1 so again, the oxidation number is +1. CO3(carbonate) has an oxidation number of -2. As far as I know, you can find the oxidation number for CO3 because all charges together come out to be zero. With Na and H adding up to 2, CO3 can be seen to be -2. Also, CO3 is -2 because it's Lewis structure is two electrons short from being complete.
+4 oxygen has an oxidation of -2, so do 3 times -2=-6, i believe Ca is a +2 and you must get the numbers to equal 0. so the answer is a +4
Na2CO3(aq) + NiCl2(aq) --> NiCO3(s) + 2NaCl(aq)
C is +4, each oxygen is -2
there are two ions. Ni and CO3.

With the 2 oxidation state. NiCO3
Nickel carbonate is NiCO3 with the molar mass 118,7 g.
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
+4 oxygen has an oxidation of -2, so do 3 times -2=-6, i believe Ca is a +2 and you must get the numbers to equal 0. so the answer is a +4
Na2CO3(aq) + NiCl2(aq) --> NiCO3(s) + 2NaCl(aq)
No, NiCO3 is not likely to be soluble in water, it is in acid.
+2 because CO3 has a charge of -2 and both they should equal to 0
Carbon has an oxidation number of +4 in both carbonate and bicarbonate. Oxygen as usual has an oxidation number of -2, and hydrogen has an oxidation number of +1. Therefore, the ion CO3-2 has six negative charges from oxygen partly balanced by four positive changes from carbon for a net of -2, and HCO3-1 has six negative charges from oxygen partly balanced by one positive from hydrogen and needs for plus four from carbon for an overall value of -1.
