Question

An industrial manufacturer wants to convert 175 kg of methane into HCN. Calculate the masses of ammonia and molecular oxygen required for this synthesis.

Answer 1

There are two industrial processes for the pruduction of HCN using methane.
\[2CH _{4}+ 2NH _{3} + 3O _{2} \rightarrow 2HCN + 6H _{2}O\] Andrussow oxidation
\[CH _{4} + NH _{3} \rightarrow HCN + 3H _{2}\] Degussa process

Answer 2

The Andrussow oxidation is the more popular method though.

Answer 3

And oh yeah. I didnt see the oxygen in your question, so it is indeed the first equation

Answer 4

mole ratio of methane and ammonia is 1 : 1
Find the number of moles of methane in 175kg.
That will also be the number of moles of ammonia required.
convert that to mass of ammonia required.

Answer 5

mole ratio of methane and oxygen is 2:3
Find the number of moles of methane in 175kg.
convert it to number of moles of oxygen required using the 2:3 mole ratio.
convert the number of moles of oxygen needed to mass of oxygen needed

Answer 6

you will need the molecular mass of ammonia, methane and oxygen.
\[no. of moles = \frac{ mass }{ M _{r} }\]
