Complete and balance the molecular equation for the reaction of aqueous sodium sulfate, Na2SO4,Na2SO4, and aqueous barium nitrate, Ba(NO3)2.Ba(NO3)2. Include physical states. molecular equation: Na2SO4(aq) Ba(NO3)2(aq)⟶Na2SO4(aq) Ba(NO3)2(aq)⟶

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced molecular equation for the reaction of aqueous sodium sulfate, and aqueous barium nitrate is :

sry but any answer choices

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
