(D) on hydrolysis gives again gas (B). This discussion on Which of the following gives propyne on hydrolysis a. Al4C3 b. Mg2C3 c. B4C d. La4C3. The ion when subjected to hydrolysis gives methylacetylene. ... {P4O6}?$ A. What could be the formulae of calcium carbide and the two products of hydrolysis? is done on EduRev Study Group by NEET Students. (B),(C) and (D) are respectively Carbonates of beryllium and Aluminum are unstable. M g 2 C 3 + 4 H 2 O → C H 3 C ≡ C H + 2 M g ( O H ) 2 . Question 40. Uses of Alkaline Earth Metals Calcium Carbonate. Carbide of Be – beryllium carbide (Be 2 C) and Al – aluminium carbide (Al 4 C 3) give methane on hydrolysis. The pure form is made by: … Share Tweet Send [Deposit Photos] Al₄C₃ is a bi­na­ry com­pound of alu­minum and car­bon which is bro­ken down quite eas­i­ly by wa­ter (hy­drolyzes) or by di­lut­ed so­lu­tions of acids. calcium carbide products A Ca2C CaO and C2H4 Both form carbide, that on hydrolysis yields Methane. Multiplying the volume in L by the molarity in mol/L gives moles of HCl: 25.0 mL (1 L / 1000 mL) (0.200 mol HCl / 1 L) = 0.00500 mol HCl in the solution For each answer choice, perform the same calculation to identify the correct match: 12.5 mL (1 L / 1000 mL) (0.400 mol HCl / 1 L) = 0.00500 mol HCl 9 C. 10 D. 12 I went for options A and B as in cold water $1$ mole of $\ce{P4O6}$ on hydrolysis give ... inorganic-chemistry hydrolysis pnictogen.
