In an unknown liquid, the percentage composition with respect to carbon, hydrogen and iodine is 34.31%, 5.28% and 60.41% respectively.
Let the mass of liquid be 100 g thus, mass of carbon, hydrogen and oxygen will be 34.31 g, 5.28 g and 60.41 g respectively.
To calculate molecular formula of compound, convert mass into number of moles as follows:

Molar mass of carbon, hydrogen and iodine is 12 g/mol, 1 g/mol and 126.90 g/mol.
Taking the ratio:

Putting the values,

Thus, molecular formula of compound will be 
.
 
        
             
        
        
        
<u>Answer:</u>
The correct answer option is a) collisions between the particles and surrounding molecules.
<u>Explanation:</u>
The collisions between the particles and surrounding molecules causes the Brownian motion of particles in a colloid.
Brownian motion is the irregular movement of the microscopic particles in a fluid which bombard into each other.
It basically is the result of the molecules of a dispersion medium colliding with the dispersed particles of the phase.

Answer: Option (d) is the correct answer.
Explanation:
When two or more different substances are mixed together then it results in the formation of a mixture.
Mixture are of two types, that is, homogeneous mixture and heterogeneous mixture.
In homogeneous mixture, the constituent particles are distributed evenly throughout the mixture. 
Whereas in heterogeneous mixture, the constituent particles are non-uniformly distributed.
Thus, we can conclude that mixtures are classified based on the distribution of particles in them.
