Chemistry Module 1

What is a mixture made of, and what is important to remember about them

Two or more substances physically combined, they are NOT chemically bonded, each substance keeps its own properties, and it can be separated using physical methods.

What are the types of mixtures, and some characteristics of them

Homogenous mixture:

Looks the same throughout, evenly distributed components. e.g sat water, air, vinegar

Heterogeneous mixture:

Visible different parts, components are not evenly distributed. e.g sand and water, oil and water

What is a volatile substance

Evaporates easily, with a relatively low boiling point

What is a non-volatile substance

does not evaporate easily, a low boiling point

What physical property does sieving take advantage of/ how does it work

The different meshes of the sieve allow smaller particles to pass through while larger particles are trapped.

What
