x N2(g) + y H2(g) → z NH3 Which of the followings about the given reaction is wrong? (N:14 g/mol, H: 1 g/mol) O A) If 1.5 moles of N2 reacts with enough H2, 51 gr NH3 is produced. B) To produce 68 gr NH3, 6 gr H2 is needed in the presence of excess N2. O) If equal number of N2 and H2 molecules react, N2 remains after the reaction. ) D) x:1; y:3; z:2 O E) Molecular geometry of NH3 is triangonal pyramidal.

In the reaction 2NH3 + CO2 - -- > CO(NH2)2 + H2O, 8 moles of NH3 react with 8 moles of CO2, the obtained amount of CO(NH2)2 in moles will be: O 10 8. O 4 O 2
