Complete and balance the molecular equation, including phases, for the reaction of aqueous sodium sulfate, Na2SO4, and aqueous b
2 answers:
<u>Answer:</u> The balanced molecular equation is written below.
<u>Explanation:</u>
A molecular equation is defined as the chemical equation in which the ionic compounds are written as molecules rather than component ions.
When sodium sulfate reacts with barium nitrate, it leads to the formation of white precipitate of barium sulfate and an aqueous solution of sodium nitrate.
The balanced chemical equation for the above reaction follows:
By Stoichiometry of the reaction:
1 mole of aqueous solution of sodium sulfate reacts with 1 mole of aqueous solution of barium nitrate to produce 1 mole of solid barium sulfate and 2 moles of aqueous solution of sodium nitrate
Hence, the balanced molecular equation is written above.
