(N/A) Homogeneous mixture:
$1$. Its constituent particles cannot be seen easily.
$2$. There are no visible boundaries of separation in a homogeneous mixture.
$3$. Its constituents cannot be easily separated.
$4$. Examples: Alloys,solution of salt in water,etc.
Heterogeneous mixture:
$1$. Its constituent particles can be seen easily.
$2$. It has visible boundaries of separation between the constituents.
$3$. Its constituents can be separated by simple physical methods.
$4$. Examples: Mixture of sand and common salt,mixture of sand and water,etc.
