6. The Haber process for making ammonia (NH) gas from its elements was developed by Fritz Haber
during WWI. Haber hoped to use ammonia as
fertilizer to grow food for Germany during the
Allie's blockade. How many liters of hydrogen
would be required to produce 40.0L of ammonia at
STP? N+H, NH,

60 Liters

Explanation:

The equation for this reaction is given as;

N2 + 3H2 → 2NH3  

From the reaction;

3 mol of H2 produces 2 mol of NH3

At STP;

1 mol = 22.4 L

This means

67.2 L ( 3 * 22.4) of H2 produces 44.8 L ( 2 * 22.4) of NH3

How many L of H2 would produce 40 L of NH3

67.2 = 44.8

x = 40

Solving for x;

x = 40 * 67.2 / 44.8

x = 60 L

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

ok whats the question if not i cannot you i need question and need a thing to answer
