Chemistry please help​

A. Process: I think it’s the Haber Process.

b. The substance represented by the letter C is Hydrogen.

c. The conditions represented by Y and Z needed for the process are 450 degrees Celsius and 200 atm, respectively.

d. i. The catalyst used is a finely divided iron (Fe) catalyst.
ii. I think the main ore from which the catalyst is extracted is Iron.

e. Balanced chemical equation for the reaction shown in the diagram:
N2(g) + 3H2(g) ⇆ 2NH3 (g)

f. One use of Ammonia is as a fertilizer.

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml
