You are preparing an aqueous sodium hydroxide solution and notice that the volumetric flask gets quite warm while dissolving the solid. Answer questions 9-10 to analyze the situation. What is the balanced equation for the reaction that has taken place? A. NaOH(s) rightarrow Na^+(aq) + OH^-(aq) B. Na^+(aq) + OH^-(aq) rightarrow NaOH(s) C. NaOH(s) rightarrow Na^+(s) + 1/2O_2(g) + 1/2H_2(g) D. Na(s) + 1/2O_2(g) + 1/2H_2(g) rightarrow NaOH(s)
