biodegradable polymers
what are the examples of biodegradable polymers
Help me to solve this problem. 0.5 M of H2AO4 is diluted from 1 lire to 10 litre, normality of resulting solution is : (a)1 N (b) 0.1 N (c)10 N (d)11 N
Unit of measurement- These are also some systems for units: (1) C.G.S.
The relative lowering of vapour pressure of 0.2 molal solution in which solvent is benzene
Give me answer of this question. When a non-volatile solute is dissolved in a solvent, the relative lowering of vapour pressure is equal to: (a) Mole fraction of solute (b) Mole fraction of solvent (c) Concentration of the solute in grams per litre
Crystals of the covalent compounds always contain:(i) Atoms as their structural units (ii) Molecules as structural units (iii) Ions held altogether by electrostatic forces (iv) High melting pointsAnswer: (i)
Give me answer of this question. "Relative lowering in vapour pressure of solution containing non-volatile solute is directly proportional to mole fraction of solute". Above statement is: (a) Henry law (b) Dulong and Petit law (c) Raoult's law (d) Le-Chatelier's pri
Select the right answer of the question. If one mole of any substance is present in of solvent, then: (a) It shows molar concentration (b) It shows molal concentration (c) It shows normality (d) It shows strength.
