The answer to your question is:

a) Hydrogen

b) 850 g of NH3

c) 300 g of N2

Explanation:

                                       N2    +     3H2    ⇒    2NH3

N2 = 1000 g

H2 = 150 g

a. Identify the limiting reactant.

MW N2 = 28 g

MW H2 = 2 g        

MW NH3 = 17g                            

                                    N2    +     3H2    ⇒    2NH3

                                   28g  3(2)

                               1000 g   x

                              x = (1000 x 6)/ 28

                             x = 214.3 g of H2

Then, the limiting reactant is H2, because is necessary to have 214.3 g of H2 to react with 1000 g of N2, and there are only 150 g.

b. Calculate the theoretical yield in grams of NH3.

                                  N2    +     3H2    ⇒    2NH3                                

                                                    6g 2(17)g

                                               150g   x

                                              x = (150 x 34) / 6

                                              x = 850 g of NH3

c. Calculate the grams of excess reactant.

                                  N2    +     3H2    ⇒    2NH3

                                 28g  6 g

                                  x 150 g

                                 x = (150 x 28)/ 6

                                 x = 700 g of N2

Excess reactant = 1000g  - 700g

                          = 300 g of N2

i believe the answer is true.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
