How much ammonia (NH3) can be obtained when 3.0g H2 reacts with 100g N2?

Answer 1

Mateo Aguilar

Approx. #8*g#.

We require (i) a plan of action:

#1/2N_2(g) + 3/2H_2 rarr NH_3(g)#

Additionally, (ii) the molar amounts of every reagent

#H_2#, #(3.0*g)/(2*g*mol^-1)# #=# #3/2*mol# #H_2#;

#N_2#, #(100.0*g)/(28*g*mol^-1)# #=# #3.3*mol# #N_2#;

Clearly, dihydrogen is in deficiency, and dinitrogen is in vast excess. So at most we can make #1/3# #xx# #3/2*mol# #=# #1/2# #mol# ammonia, # ~~# #8*g#.

Industrial ammonia synthesis involves large amounts of ammonia. Why is this reaction significant?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
