Answer

(a) 2 moles of NH3 (b) 6 molecules of H2 (c) 6 moles of H2

Work Step by Step

(a) 1 mole of N2 reacts with 3 moles of H2O; Products: 2 moles of NH3 (b) From the given equation, each molecule of N2 reacts with 3 molecules of H2. So, 6 molecules of H2 are required to completely react with two molecules of N2. (c) From the given equation, each mole of N2 reacts with two moles of H2 to form 2 moles of NH3. So, six moles of H2 are required to completely react with two moles of N2.
