A chemistry student wants to see the effect of adding a specific buffer on the equilibrium position of a 0.1 M acetic acid (CH3COOH) and 0.1 M sodium acetate (CH3COONa) solution. If the initial pH of the solution is 4.7, what is the pH of the solution after adding the buffer? (Ka of acetic acid is 1.8 x 10^-5).

A chemist mixes 0.1 mol of hydrogen (H2) with 0.2 mol of nitrogen (N2) in a 2 L flask at 400°C. The reaction H2(g) + N2(g) ⇌ 2NH3(g) establishes equilibrium. Calculate the equilibrium concentrations of hydrogen, nitrogen, and ammonia if the Kc value of the reaction at this temperature is 1.5 x 10^-2.
