Calculate the empirical formula and the molar formula.
Draw a mechanism to demonstrate how pyridine catalyzes the hydrolysis of acetic anhydride to two molecule of acetic acid. Is this reaction reversible? why or why not?
Discuss the probable reasons for the differences in flow patterns in a horizontal heated tube as compared to (i) vertical heated tube (ii) horizontal unheated tube?
The reaction that occurs here is the reaction of iodide ions with peroxydisulfate ions to produce iodine molecules and sulfate ions. Write the balanced net ionic equation for this reaction.
