Question

. Two packets contain brass and sand. Classify
them into homogeneous and heterogeneous mix-
tures. Justify your answer.
​

Answer 1

$\textcolor{green}{Answer :-}$

Brass is a homogeneous mixture.

Sand is a heterogeneous mixture.

$\textcolor{red}{Explanation :-}$

Brass is an alloy of Cu(copper) and Zn(zinc). Brass is prepared by combining/mixing these two metals. Hence, brass is a homogeneous mixture because it has the same composition throughout it or it looks the same throughout.

Sand consists of different proportions of silt, humus and other materials at different layers. Hence, it is a heterogeneous mixture because it does not have a uniform composition and appearance throughout it.
