What is the % yield of 7.50g of nitrogen reacted with 1.30g of hydrogen and 5.75 g of ammonia is produced

how to use Molecular orbital theory to determine the hybridization of the metal centre in the complex.

1. [RhCl3(OH)3]3-

2. [Cr(en)2(PMe3)2]

Determine the hybridization of the metal centre in the complexes below using Ligand Field Theory.

1. [RhCl3(OH)3]3-

2. [Cr(en)2(PMe3)2]

Given the following data:

2 H2 (g) + C (s) → CH4 (g) ΔG° = -51 kJ

2 H2 (g) + O2 (g) → 2H2O (ℓ) ΔG° = -474 kJ

C (s) + O2 (g) → CO2 (g) ΔG° = -394 kJ

Calculate ΔG° for CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H2O (ℓ).

Calculate the volume of 10.0 carat diamond (1 carat at = 200.0mg). The density of diamond is 3.51g/ml?

Balance the following reaction using changes in oxidation number,with steps

A mixture of 0.300 mol H2 and 0.300 mol N2 was placed in a 1.00L stainless-steel flask at 430°C. The equilibrium constant Kc for the following reaction is 0.65 at 395°C. The gas constant R=0.08206 L.Atm/mol.K
N2(g) + 3H2(g) = 2NH3(g) (PS: please take the = sign to mean a reversible reaction).
a) what's the value of Kp for this reaction?
b) what's the value of the equilibrium constant Kc for
2NH3(g) = N2(g) + 3H2(g)
c) What's the value of the equilibrium constant for Kc for
1/2N2(g) + 3/2H2(g) = NH3(g)
d) What are the values of Kp for the reactions described in (b) and (c)
Thanks!!!!!!!!
