Explanation / Answer

Answer

37) liquid D

38) liquid C

39) liquid D

Explanation

Compounds which having the stronger inter molecular force having higher boiling point

Compounds having which having lower vapour pressure will have lower boiling point

Compound having which having higest boiling point is least valotile

40)

Answer

104.94g

Explanation

N2(g) + 3H2(g) ------> 2NH3(g)

Stoichiometrically, 2moles of NH3 comes from 3moles of H2

No of mole of H2 = mass of H2/Molar mass of H2

= 18.62g/2.014(g/mol)

= 9.245mol

No of mole of NH3 produced =( 2/3) × 9.245mol =6.163mol

   mass of NH3 = mole of NH3 × molar mass of NH3

   = 6.163mol × 17.028g/mol

   = 104.94g
