What is the concentration of NaCl in a solution if titration of 15.00 mL of the solution with 0.2503MAgNO3 requires 20.22 mL of the AgNO3 solution to reach the end point?
AgNO3(aq) + NaCl(aq)⟶AgCl(s) + NaNO3(aq)

(f)\(Rb{O_2}\), rubidium superoxide
(g)\(HF\)
Write a balanced equation for the decomposition of ammonium nitrate to form molecular nitrogen, molecular oxygen and water. (Hint Balance oxygen last, since it is present in more than one molecule on the right side of the equation)
Outline the steps needed to solve the following problem, then do the calculations. Ether,\({\left( {{C_2}{H_5}} \right)_2}O\), which was originally used as an anesthetic but has been replaced by safer and more effective medications, is prepared by the reaction of ethanol with sulfuric acid.\(2{C_2}{H_5}OH + {H_2}S{O_4} \to \left( {{C_2}{H_5}} \right)2O + {H_2}S{O_4} \cdot {H_2}O\)What is the percent yield of ether if 1.17 L (d = 0.7134 g/mL) is isolated from the reaction of 1.500 L of C2H5OH (d = 0.7894 g/mL)?
What volume of 0.600 M HCl is required to react completely with 2.50 g of sodium hydrogen carbonate?
\({\rm{NaHC}}{{\rm{O}}_{3(aq)}}{\rm{ + HC}}{{\rm{l}}_{(aq)}}{\rm{ }} \to {\rm{ NaC}}{{\rm{l}}_{(aq)}}{\rm{ + C}}{{\rm{O}}_{2(aq)}}{\rm{ + }}{{\rm{H}}_2}{{\rm{O}}_{({\rm{l}})}}\)
