Question

17gm of NH3 on decomposing gave 0.14 gm of N, and 366 ml of H2. at N.T.P. Show
that data illustrates the law of conservation of mass...
(note):22400ml of H2=2 gm.
​

Answer 1

2NH³⟶N²+3H²

$Moles \: of \: ammonia= \frac{17}{170} =10$

2 moles of ammonia will produce 1 mole of nitrogen and 3 moles of hydrogen.

10 moles of ammonia will produce 5 moles of nitrogen 15 moles of hydrogen.

5 moles of nitrogen=5×28=140g

15 moles of hydrogen=15×2=30g

Answer 2

2NH³⟶N²+3H²

2NH³⟶N²+3H²

ɱσℓεร σƒ αɱɱσɳเα = 17/170 = 10

2 moles of ammonia will produce 1 mole of nitrogen and 3 moles of hydrogen.

10 moles of ammonia will produce 5 moles of nitrogen 15 moles of hydrogen.

5 moles of nitrogen=5×28=140g

15 moles of hydrogen=15×2=30g
