Splet(Ans. 1.5 mole) (c) How many moles of H2O are needed to make 12 moles of NH3? (Ans. 36 moles) (d) Calculate the mass of Ca(OH)2 that can be formed from the reaction of 10.0 g of Ca3N2 with an excess of H2O. Solution: moles Ca3N2 = 10.0 g Ca3N2 x = 0.06743 mole 1 mole Ca3N2 148.3 g Ca3N2 moles Ca(OH)2 = 0.06743 mole Ca3N2 x = 0.2024 mole 1 … Splet2H2O2 (aq.) ¾¾ ® 2H2O (l) + O2 (g) under conditions where one mole of gas occupies 24 dm3, 100 cm3 of XM. solution of H2O2 produces 3dm3 of O2. X is thus : (A) 2.5 (B) 1 (C) 0.5 (D) 0.25. 12. One mole of a mixture of CO and CO2 requires exactly 20 gram of NaOH in solution for complete conversion of.

Splet(a) needs 5 moles (5 electrons per N, times 2 to get N2 and then 0.5 moles = 5. (b), change in oxidation number is 4, 2 nitrogens to get N2O 0.5 moles = 4 moles of electrons. (c) … SpletWhen HNO3 solution is added to NaOH solution, then 0.2 mole of HNO3 solution will combine with 0.2 mole of OH- ions of NaOH solution.∴ Heat released= ∆H x 0.2 = 57 x 0.2 = 11.4 kJ.
