As upon dissolution of NaCl
NaCl (s) ====> Na+ (aq) + Cl -(aq)
As there is hydrolysis means cation ad anion are sorrounded by solvent water by dipole ion force and previous ion ion forces between cation and anion are now broken. So new hydrated specie is formed so its a Chemical reaction
And these hydrated ion given conductivity to solution when voltage is applied
So and is last option I, III & IV

Write ionic equations, similar to the one above, that describe
how NaNO3 and NaCH3CO2 each
dissociate as they dissolve in water. Include heat as a reactant or
product in each equation.
Here is what I answered:
NaNO3 (s) = Na+ +
NO3- + heat
NaC2H3O2 + Heat =

g of sodium nitrate (NaNO,) dissolves in 100 g of water at 20°C. Is this solution saturated or unsaturated? Wha t would happen if you added ten more grams of sodium nitrate to the solution? What would if you added the ten grams and raised the temperature to 40 C? lution is unsaturated. Adding ten additional grams of solute (NaNO,) would result in a homo geneous solution. Raising the temperature of the solution by 20°C would not affect the solution...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
