at this post you will find chemistry exam for university entrance with year 2005, this exam (soal) 10 number with only 2 page of pdf, at this  exam or test you will find chemistry problem  such us  Avogadro law, what is that ? Avogadro law : ” Equal volumes of gases, at the same temperature and pressure, contain the same number of particles, or molecules.

Thus, the number of molecules in a specific volume of gas is independent of the size or mass of the gas molecules. As an example, equal volumes of molecular hydrogen and nitrogen would contain the same number of molecules.

where:

V is the volume of the gas.
n is the number of moles in the gas.
k is a constant.

The ideal gas constant has the same value for all gases.

and then about functional of isomer, koloid ,A Colloid or colloidal dispersion is a type of heterogeneous mixture . A colloid consists of two separate phases: a dispersed phase and a continuous phase. In a colloid, the dispersed phase is made of tiny particles or droplets that are distributed evenly throughout the continuous phase. The size of the dispersed phase particles are between 1nm and 1000nm in at least one dimension. Homogeneous mixtures with a dispersed phase in this size range may be called colloidal aerosols, colloidal emulsions, colloidal foams, or colloidal dispersions.
