Write a balanced chemical equation for the reaction of aqueous sodium carbonate with aqueous strontium chloride to form solid st
stira [4]

Answer:

The answer to your question is below

Explanation:

Data

Aqueous sodium carbonate = Na₂CO₃ (aq)

Aqueous strontium chloride = SrCl₂ (aq)

Solid strontium carbonate = SrCO₃ (s)

Aqueous sodium chloride = NaCl (aq)

Unbalnced Chemical reaction

                  Na₂CO₃(aq)  +   SrCl₂(aq)   ⇒  SrCO₃(s)  +  NaCl(aq)

                       Reactants               Elements        Products

                             2                       Sodium                  1

                              1                       Carbon                   1

                              1                       Strontium                1

                              2                       Chlorine                 1

                              3                       Oxygen                  3

Balanced Chemical reaction

                  Na₂CO₃(aq)  +   SrCl₂(aq)   ⇒  SrCO₃(s)  +  2NaCl(aq)

                       Reactants               Elements        Products

                             2                       Sodium                  2

                              1                       Carbon                   1

                              1                       Strontium               1

                              2                       Chlorine                2
