In the reaction \(2\,\mathrm{NaCl} + \mathrm{H_2SO_4} \rightarrow \mathrm{Na_2SO_4} + 2\,\mathrm{HCl}\), 5.0 g of NaCl are mixed with 4.0 g of \(\mathrm{H_2SO_4}\). Determine which reactant is the limiting reagent, calculate the mass of \(\mathrm{Na_2SO_4}\) that can be formed, and state the percent excess of the other reagent.

Answer Options

A. Limiting reagent: \\(\\mathrm{NaCl}\\); \\(\\mathrm{Na_2SO_4}\\) formed = 5.80 g; NaCl excess = 0 %
Correct Answer B. Limiting reagent: \(\mathrm{H_2SO_4}\); \(\mathrm{Na_2SO_4}\) formed = 5.80 g; NaCl excess = 4.6 %
C. Limiting reagent: \\(\\mathrm{NaCl}\\); \\(\\mathrm{Na_2SO_4}\\) formed = 4.90 g; NaCl excess = 2.1 %
D. Limiting reagent: \\(\\mathrm{H_2SO_4}\\); \\(\\mathrm{Na_2SO_4}\\) formed = 6.30 g; NaCl excess = 3.8 %
Correct Answer
B
Correct Option:
Limiting reagent: \(\mathrm{H_2SO_4}\); \(\mathrm{Na_2SO_4}\) formed = 5.80 g; NaCl excess = 4.6 %
