Write balanced molecular, ionic, and net ionic equations for the reaction occurs when (a) a bacl2 (barium chloride) is mixed with a solution of na2so4 (sodium ) hbr (hydrogen bromide) with ba(oh)2 (barium hydroxide)(c) hno2 mixed with ba(oh)

A.) We write the molecular equation for the chemical reaction as:

BaCl2(aq)+Na2SO4(aq)→BaSO4(s)⏐+2NaCl(aq)

Alternatively, we could write the net ionic equation:

Ba2+ + SO2^−4→ BaSO4(s)⏐

B.)We write the molecular equation for the chemical reaction as:

Ba(OH)^2 + 2HBr → BaBr2 + 2H2O

The ionic equation can be written as;

Ba^2+ + 2OH^- + 2H^+ + 2Br^- →

Ba^2+ + 2Br^- + 2H2O

the net ionic equation can be written as;

2OH^- + 2H^+ → 2H2O

Alternatively, we could write the net ionic equation

OH^-(aq) + H^+(aq) → H2O(l) net ionic equation.

C.) We write the molecular equation for the chemical reaction as:

2 HNO2(aq) + Ba(OH)2(aq) 

→ Ba(NO2)2(aq) + 2 H2O(l)

Net ionic equation

HNO2(aq) + OH-(aq) → NO2-(aq) + H2O(l)

Alternatively, we could write the net ionic equation as:

2H^+ + 2OH → 2H2O

your answer would be “dry”
