+2 because CO3 has a charge of -2 and both they should equal to 0
Ni has a charge of +4. This is because each Cl has a -1 charge. Since each compound must be electrically neutral Ni has to be +4 in order to cancel out the 4 (-1) charges on the four Cl.
there are two ions. Ni and CO3.
3+
there are two ions. Ni and CO3.
No, NiCO3 is not likely to be soluble in water, it is in acid.
In pure water, there are no calcium ions.
The ions corresponding to the electrolyte i.e. both anions and cations are present in an electrolyte. These ions may be similar to the electrodes dipped in it.
The precipitation of solid nickel carbonate, NiCO3, in aqueous solution is represented by:Ni2+(aq) + CO32-(aq) NiCO3(s)From the Solubility Rules we know that:Carbonates and phosphates are NOT soluble except those also containing Na+, K+ or NH4+.And NiCO3 is NOT SOLUBLE.
there are two ions. Ni and CO3.
No, NiCO3 is not likely to be soluble in water, it is in acid.

The number of chloride ions present in a given substance depends on the substance size and the type of substance.
6
The answer is 0,325.10e23 ions.
9.03x10 23 ions
In pure water, there are no calcium ions.
