Answer 1

2Na_2Co_3_(aq) + 3 CO(NO_3)_3(aq) rightarrow 6NaNo_3(aq) + CO_2(CO_3)_3 (s) The reaction between sodium carbonate and cobalt(III) chloride is as follows COCl_2_(aq) + Na_2CO_3(aq) rightarrow CoCo_3(s) + 2NaCl(aq) Ionic Equation, CO^+ 2(aq) + 2 Cl^-_(aq) + 2 Na^+ (aq) + CO_3^2- (aq) COCO_3(s) + 2Na^+(aq) + 2Cl^-(aq) Net Ionic Equation, CO^+ 2(aq) + CO_3^2- (aq) rightarrow COCO_3(s) BaCl_2(aq) + Na_2SO_4(aq) rightarrow BaSO_4(s) + 2NaCl(aq) complete ionic Equation, Ba^+ 2 (aq) + 2Cl^-(aq) + 2Na^+ (aq) + SO_4^2- (aq) BaSO_4(s) + 2Na^+(aq) + 2Cl^-(aq) Net ionic Equation, Ba^+ 2 (aq) + SO_4^2- (aq) rightarrow BaSo_4(s)
