Question

if 28 of N2 completely reacts with 4 gram of H2 amount of Nh3 formed will be N2+3H2----------->2NH3 (a)22.66g (b) 32g (c) 34g (t) 30g​

Answer 1

Answer:

I think the answer will be 30g

Answer 2

Answer: (a) 22.66 g

Explanation:

N2      +    3H2   --------------------->  2NH3

1 mole      3 mole                            2 mole

3 mole H2 produces 2 mole NH3.

Molecular mass of (H2, NH3) = (2, 14 + 3) = (2, 17)

Therefore, (3 x 2) g H2 produces (2 x 17) g NH3

             or, 1 g H2 produces 34/6 g NH3

             or, 4 g H2 produces 4 x (34/6) g NH3 = 22.66 g NH3
