how can you seperate two immiscible liquids ?
(d) Sol is a liquid-solid colloid and Gel is a solid-liquid colloid
state some examples of diffusion in solid, gases, liquid
(d) Blood is a compound and sea water is a mixture
is air a mixture or compound? give 3 reasons.
what is crystallization?
the spaces between the constituent particles are maximum in gases
(a) How can we separate a mixture of two miscible liquids ?
10 difference between 3 states of matter
what is the difference between distillation and fractional distillation in tabular form?and dont tell mw that go to this link . give me this answer by typing in tabular form.
What is the dispersed phase and the dispersion medium in milk?
How can you distinguish between a salt solution and a pure liquid without tasting it?
why is crystallization technique better than evaporation
5g of sugar is dissolved in 250 ml of solution.Calculate its mass % by volume
why do liquids flow ? Explain .
State three reasons why you think air is a mixture and water is a compound.
Differentiate between miscible and immiscible liquids..
what mass of water must be added to 5g of Nacl to make 5% mass by mass percentage of the solution ?????????.............
difference between aqueous and non aqueous solutions?
Beakers A and B contains a solution of potassium permanganate and a mxiture of chalk powder in water . Mention one point of difference that you would observe in the two mixtures . On the basis of the observation categorise the two as homogeneous and hetrogeneous mixture.
define aerosol, emulsion, sol, gel
List out the difference between Solution,Suspension and Colloidal Sollution in all aspects.

(d) Blood is a compound and sea water is a mixture
is air a mixture or compound? give 3 reasons.
it is a white crystalline solid
upon keeping in air it slowly becomes black.
it does not dissolve in water even upon heating
its constituents cannot be easily separated
it decomposes when exposed to sunlight to evolve a greenish yellow gas with pungent smell.
Based on above information answer the foll
a) Is the substance element or compound
b) Which gas is evolved on exposing A to sunlight?
c)What is the nature of reaction when the substance A is exposed to sunlight?
d)Identify the substance A

(a) How can we separate a mixture of two miscible liquids ?
10 difference between 3 states of matter
whether compound or a mixture.
what is the difference between distillation and fractional distillation in tabular form?and dont tell mw that go to this link . give me this answer by typing in tabular form.
a) a true solution of common salt, sugar and alum
b) a suspension of soil, chalk powder and fine sand in water
c) a colloidal solution of starch in water and egg albumin/milk in water and distinguish between
these on the basis of
? transparency
? filtration criterion
? stability
