Explanation / Answer

1) (NH4)2CO3 and CoCl2 are ionic compounds, soluble in water and react to form CoCO3 and NH4Cl. CoCO3 is insoluble. NH4Cl decomposes into ions in an aqueous solution.

The total ionic equation is

2 NH4+ (aq) + CO32- (aq) + Co2+ (aq) + 2 Cl- (aq) --------> CoCO3 (s) + 2 NH4+ (aq) + 2 Cl- (aq)

Cancel out the common ions to get the net ionic equation as

CO32- (aq) + Co2+ (aq) --------> CoCO3 (s)

2) The oxidation state of F is -1. Let the oxidation state of Cl be x in ClF3. ClF3 is electrically neutral, i.e, carries an overall zero charge. Therefore, we must write for the charge balanced,

1*x + 3*(-1) = 0

====> x – 3 = 0

====> x = +3

The oxidation state of Cl in ClF3 is +3 (ans).
