Question

question 8. match each example to its correct classification. a) air b) vegetable c) oxygen (o) d) helium (he) e) salad f) glucose (c₆h₁₂o₆) g) carbon dioxide (co₂) h) milk :: element :: compound :: homogeneous mixture :: heterogeneous mixture

Explanation:

a) Air is a homogeneous mixture as it has a uniform composition of gases like nitrogen, oxygen etc. throughout.
b) Vegetable oil is a homogeneous mixture as it has a consistent composition of various fatty - acid esters.
c) Oxygen (O) is an element as it consists of only one type of atom.
d) Helium (He) is an element as it is made up of only helium atoms.
e) Salad is a heterogeneous mixture as it contains different components like vegetables, dressings etc. that are not uniformly distributed.
f) Glucose ($C_6H_{12}O_6$) is a compound as it is made up of different elements (carbon, hydrogen, oxygen) chemically bonded together.
g) Carbon dioxide ($CO_2$) is a compound as it consists of carbon and oxygen atoms chemically combined.
h) Milk is a homogeneous mixture when well - mixed, as its components like fats, proteins, and water are uniformly distributed.
