The chiral carboxylic acid A (C5H6O2) reacts with 1 mol of hydrogen gas on catalytic hydrogenation. The product is an achiral carboxylic acid B (C5H8O2). What are the structures of Compounds A and B?
Compute how many ml of C2H3NaO2(0.2 M) need to be added to 200 mL of 0.1 M CH3COOH to make a buffer of pH 5 and also find out what would be the total concentration of C 2 H 3 O 2 be in this (acetate + acetic acid) solution ?
If the reaction 2H2S(g) ↔ 2H2(g) + S2(g) is carried out at 1065°C, Kp = 0.0120. Starting from pure H2S introduced into an evacuated vessel at 1065°C.
