Sodium carbonate is a reagent that may be used to standardize acids. In such a standardization it was found that a 0.498-g sample of sodium carbonate required 23.5mL of a sulfuric acid solution to reach the end point for the reaction.

Na2CO3 (aq) + H2SO4 (aq) ---> H2O (l) + CO2 (g) + Na2SO4 (aq)

What is the molarity of the H2SO4?

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
