A) Oleates B) stearates C) Palmitates D) Myristates Solution Answer Oleates Oils are liquids at room temperature since they contain higher percentage of oleates, it’s is monounsaturated omega 9 fatty acid.
A) 0.05 B) 0.04 C) 0.02 D) 0.01 Solution Urea = Mass/ mol mass. 3/60. = 0.05 Water= Mass/ mol mass. 45/60. = 2.5 By relative lowering of vapour pressure ∆P/Po. =. X(water) 0.05/0.05+2.5 = 0.0196 = 0.02 is the answer
A) no definite compound B) Insoluble in polar solvent C) small difference in electronegativity D) Low melting point Solution Answer A No definite geometry is not a characteristic of a covalent compound. The covalent compound has definite geometrical shape, because of the bond forms.
A) low osmotic pressure B) No osmotic pressure C) High osmotic pressure D) Very High osmotic pressure Answer All colloidal dispersion have low osmotic pressure. The osmotic pressure is a colligative property and depends on the number of solute particles. If number of solute particles in solution is low, the osmotic pressure is low. So … Read more
A) negative deviation from Raoult’s law B) positive deviation from Raoult’s law C) No deviation from Raoult’s law D) postive or negative deviation from Raoult’s law depends upon the composition Answer negative deviation from Raoult’s law
A) 48% B) 73 % C) 42 % D) 60 % Solution Lets assume Total 5 articles (sold at 100) Then 5 x100 —–500 2 x 100 —–200 But sold at 12 % loss 200x 12/100 = 176 3—-300 As per question total is % profit 500x 18/100 = 590 But already 2 sold at … Read more
A) 7804 B) 6335 C) 6405 D) 7605 Solution Mohit = 25% = 1/4 (1= profit; 4= sp) Cp =3. Sp = 4 profit=1 Soma 30% 3/10 (3 profit ; 10 cp) Cp =10 sp = 13. Profit = 3 CP. SP Mohit. 3. 4. (13) Soma. 10. 13. (4) As per question sp to … Read more
