Which statement is correct for this reaction CH_3^- (g) + NH_3 (g) rightwardsharpoonoverleftwardsharpoon CH_4 (g) notequaltoto NH_2^- (g) CH_3^- acts as a base. CH_3^- is the conjugate acid of CH_4 NH_3 act as a base. NH_2^- is a conjugate acid of NH_3. Which is conjugate acid-base pair in the real N_2 H_4 (eq) + h_2 O rightwardsharpoonoverleftwardsharpoon N_2 H_5^+ (eq) + OH^- (eq) N_2 H_4. and H_2 O N_2 H_5^+. and N_2 H_4. and N_2 H_5^+ N_2 H_4 and The pH of four different solutions was determine then small amounts of strong acid (0.01 mol) we consecutively to equal volumes of each. solutions 1 and 3 are buffers but solution 3 has greater buffer capacity than 1. solutions 2 and 4 are buffers but solution 2 has greater buffer capacity than 4. solutions 3 and 4 are buffers but solution 4 has greater buffer capacity than 3. none of the four initial solutions is a buffer. Equal volumes of solutions of acids and their sodium salts are mixed to prepare a buffer. Th

Explanation / Answer

29)
CH3- is accepting H+. SO it is base
NH3 acts as acid
CH4 is conjugate acid of CH4-
NH2- is conjugate base of NH3

Answer: A

30)
N2H4 is accepting H+. SO it is base and N2H5+ is its conjugate acid
so, N2H4 and N2H5+ are conjugate acid-base pair

similarly H2O and OH- are conjugate acidi- base pair
