Chemistry

a) Ammonia, an important source of fixed nitrogen that can be metabolized by plants, is produced using the Haber process in which nitrogen and hydrogen combine.

N2(g) + 3H2(g) → 2NH3(g)

How many grams of nitrogen are needed to produce 325 grams of ammonia?

b)A 0.00100 mol sample of Ca(OH)2 requires 25.00 mL of aqueous HCl for neutralization according to the reaction below. What is the concentration of the HCl?

Equation: Ca(OH)2(s) + 2HCl(aq) → CaCl2(aq) + H2O(l)

  1. N 14 g/mol
    H 1 g/mol

    NH3 is therefore 17 g/mol, 2NH3 is 34
    N2 is 28 g/mol

    every 2 mol of NH3 requires 1 MOL OF N2
    so
    every 34 g of NH3 requires 28 g of N2
    so finally
    325 g NH3 (28 N2/34 NH3) = 268 g N2

  2. every .001 mol Ca(OH)2 needs .002 mol of HCl
    so
    we have .002 mol in 25*10^-3 liters
    .002/.025 = .08 mol/liter
