Respuesta :

formation of ammonia by nitrogen and hydrogen is habers process wher 28g N2 results in formation of 34g NH3
so 35g N2 will form 34*35/28=42.5g NH3 where it given that reaction takes place in excess of H2
N2+3H2 gives 2NH3

Answer:

[tex]Mass_{NH_3}= 42.5775\ g[/tex]

Explanation:

Moles of [tex]N_2[/tex]:-

Mass = 35.00 g

Molar mass of [tex]N_2[/tex] = 28.014 g/mol

The formula for the calculation of moles is shown below:

[tex]moles = \frac{Mass\ taken}{Molar\ mass}[/tex]

Thus,

[tex]Moles= \frac{35.00\ g}{28.014\ g/mol}[/tex]

[tex]Moles_{N_2}= 1.25\ mol[/tex]

According to the reaction:-

[tex]N_2_{(g)} + 3H_2_{(g)}\rightarrow 2NH_3_{(g)}[/tex]

1 mole of [tex]N_2[/tex] on reaction forms 2 moles of [tex]NH_3[/tex]

1.25 mole of [tex]N_2[/tex] on reaction forms 2*1.25 moles of [tex]NH_3[/tex]

Moles of [tex]NH_3[/tex]  = 2.5 moles

Molar mass of [tex]NH_3[/tex] = 17.031 g/mol

The formula for the calculation of moles is shown below:

[tex]moles = \frac{Mass\ taken}{Molar\ mass}[/tex]

Thus,

[tex]2.5\ mol= \frac{Mass}{17.031\ g/mol}[/tex]

[tex]Mass_{NH_3}= 42.5775\ g[/tex]
