2. A classification of matter wherein the components cannot be identified from one
another?
_ OM _ GE _ _ O _S
ans: HOMOGENEOUS
3. A type of change in matter wherein the identity and properties of matter are retained.

4. QUESTION
1. what is common to the picture shown?
2. how about the difference among them?
3. What type of solution is present in each sample of solution?
MATTER is classified as puresubstance or mixture.
Pure substance= definite composition,distinct properties
Mixture+combination of different substances that retain its own properties
Properties of matter
physical+=properties that can be determine without changing the composition of the msterial.example; codor ordor mass , length
Chemical properties:
On the basis of physical states of solvent and solute can be categorized as solid, liquid and gaseous solutions.
In solid solutions, solute and solvent are in the solid-state. For example ceramics, and polymer blends. In liquid solutions, solid, gas or liquid is mixed in a liquid state. Gaseous solutions are usually homogenous mixtures of gases like air. Depending upon a number of solutions and solute, it can be classified into dilute and concentrated solutions.

Because this definition places no restriction on the nature of the substances involved, we can distinguish six types of solutions, depending on the original states (solid, liquid, or gas) of the solution components. Table 13.1 gives examples of each of these types.
