(ii) Mg₃N₂ + H₂O →
(iii) K₂Cr₂O₇ + conc. HCl →
(iv) CH₃COONa + NaOH (soda lime, Δ) →
(Given : H = 1, C = 12, N = 14, O = 16, Cl = 35.5)

Question

Consider the given reactions and write the sum of the molecular weights of the products which are gases at room temperature :

(i) H₂O₂ + KMnO₄ (acidic medium) →

(ii) Mg₃N₂ + H₂O →

(iii) K₂Cr₂O₇ + conc. HCl →

(iv) CH₃COONa + NaOH (soda lime, Δ) →

(Given : H = 1, C = 12, N = 14, O = 16, Cl = 35.5)

TestHub · Accepted Answer

(i) O₂ (32) ; (ii) NH₃ (17) ; (iii) Cl₂ (71) ; (iv) CH₄ (16). Sum = 32 + 17 + 71 + 16 = 136.
