Answer:

d) 2.7 mol

Explanation:

  • 3 H2 + N2 → 2 NH3

limit reagent is H2:

∴ Mw H2 = 2.016 g/mol

∴ Mw N2 = 28.0134 g/mol

⇒ moles NH3 = (4.0 moles H2)×(2 mol NH3/3mol H2)

⇒ moles NH3 = 2.666 mol

⇒ moles NH3 ≅ 2.7 mol

Explanation:

Data

Chemical reaction

                   (NH₄)₂CO₃  ⇒   NH₃  +  CO₂  + H₂O

               Reactants    Elements     Products

                      2            Nitrogen             1

                       1            Carbon                1

                       8           Hydrogen            5

                       3           Oxygen                3

This reaction is unbalanced

                   (NH₄)₂CO₃  ⇒   2NH₃  +  CO₂  + H₂O

               Reactants    Elements     Products

                      2            Nitrogen             2

                       1            Carbon                1

                       8           Hydrogen            8

                       3           Oxygen                3

Now, the reaction is balanced,

The coefficient for Carbon dioxide is 1
