AP Chemistry 8.10 A Explain the Relationship Between the Buffer Capacity of a Solution and the Relative Concentrations of the Questions question 1

[Maximum number: 1]

At high temperatures, N2(g)\mathrm{N}_{2}(g) and O2(g)\mathrm{O}_{2}(g) can react to produce nitrogen monoxide, NO(g), as represented by the equation above.

A second student makes a buffer by dissolving 0.100 mol of NaNO2(s)\mathrm{NaNO}_{2}(s) in 100. mL of 1.00MHNO2(aq)1.00 M \mathrm{HNO}_{2}(a q). Which is more resistant to changes in pH when a strong acid or a strong base is added, the buffer made by the second student or the buffer made by the first student in part (c) ? Justify your answer.
