Question

Find the Molecular, Complete Ionic, and Net Ionic of each combination:

AF, AE, AD, AC, AB, BF, BE, BD, BC, CF, CE, CD, DF, DE, EF

A) Na2CO3

B) BaCl2

C) CoSO4

D) KIO3

E) NAOH

F) CoCl2

Answer 1

Na2CO3(aq) +CoCl2 (aq) --------> CoCO3(s) + 2NaCl(aq)

2Na⁺(aq)+CO3^2-(aq) +Co⁺² (aq) +2Cl^- (aq) --------> CoCO3(s) + 2Na⁺(aq) +2Cl^-(aq)

removal of specter ions to get net ionic equation

CO3^2-(aq) +Co⁺² --------> CoCO3(s)

AE no reaction

AD

Na2CO3(aq) + 2KIO3(aq) --------------> 2NaIO3(aq) + K2CO3(aq)

2Na⁺(aq)+CO3^2-(aq) + 2K⁺(aq)+IO3^-(aq) --------------> 2Na⁺(aq)+2IO3^-(aq) + 2K⁺(aq)+CO3^2-(aq)

AC

Na2Co3(aq) + CoSO4(aq) -----------> CoCO3(s) + Na2SO4(aq)

2Na⁺(aq)+Co3^2-(aq) + Co⁺²(aq)+SO4^2-(aq) -----------> CoCO3(s) + 2Na⁺(aq)+SO4^2-(aq)

Netionic equation

Co3^2-(aq) + Co⁺²(aq) -----------> CoCO3(s)

AB

Na2CO3(aq) + BaCl2(aq) -------------> BaCO3(s) + 2NaCl(aq)

2Na⁺(aq) +CO3^2-(aq) + Ba⁺²(aq)+2Cl^-(aq) -------------> BaCO3(s) + 2Na⁺(aq)+2Cl^-(aq)

CO3^2-(aq) + Ba⁺²(aq)-------------> BaCO3(s)
