Calculate the mass of ammonia produced of 2g N2 reacts with 1g H2.

OpenStudy (anonymous):

@TheMind @ujjwal @ajprincess

OpenStudy (unklerhaukus):

have you got an equation for the reaction

OpenStudy (anonymous):

no

OpenStudy (unklerhaukus):

do you know the for mula for ammonia?

OpenStudy (unklerhaukus):

is it NH_3 ?

OpenStudy (anonymous):

nh3

OpenStudy (unklerhaukus):

so far we have \[N_2+H_2 \longrightarrow NH_3\] right?

OpenStudy (anonymous):

@@@UnkleRhaukus

OpenStudy (unklerhaukus):

can you balance the equation for number of H and N on each side?

OpenStudy (anonymous):

UR EQ IS NT APPEARING

OpenStudy (unklerhaukus):

oh,

OpenStudy (unklerhaukus):

N_2 + H_2 ⟶ NH_3

OpenStudy (unklerhaukus):

so to make the product we need thee time as much H as N

OpenStudy (ujjwal):

\[N_2+3H_2\rightarrow2NH_3\] You get no of moles required from this equation! Convert them in terms of weight.. Find limiting reactant (the reactant whose quantity is less than required)! limiting reactant will determine the amount of product formed!

OpenStudy (anonymous):

Is this always the case??

OpenStudy (anonymous):

ITS AGAIN APPEARING MATHS PROCCESING ERROR

OpenStudy (mayankdevnani):

i think ujjwal is right

OpenStudy (mayankdevnani):

N2 + 3H2 ---> 2NH3

OpenStudy (mayankdevnani):

So the moles are: For nitrogen, 28g/28g/mol = 1.0 mole N2 For hydrogen 25g/2g/mole = 12.5 moles @ujjwal right...

OpenStudy (unklerhaukus):

which is the limiting reagent ?

OpenStudy (mayankdevnani):

Obviously, hydrogen is in excess and nitrogen is the limiting reagant

OpenStudy (mayankdevnani):

@UnkleRhaukus

OpenStudy (unklerhaukus):

so according to the balanced equation the theoretical yield will be 2 moles of NH_3

OpenStudy (ujjwal):

yep! 2 mol of NH3 will be yielded!

OpenStudy (unklerhaukus):

the molar mass of ammonia is (1x14+3x1) g/mol

OpenStudy (unklerhaukus):

can you finish @Ruchi. ?

OpenStudy (anonymous):

@mayank i'm nt getting u properly

OpenStudy (anonymous):

@taylorrrr @ajprincess @imron07 @TheMind @Vikt0r hlp me out

OpenStudy (ajprincess):

Where are u stuck @Ruchi.?

OpenStudy (ajprincess):

Did u understand the part where the moles are calculated?
