STUDY THE GIVEN PRESENTATION ATTACHED HERE AND ANSWER THW GIVEN QUESTIONS.
1. differentiate substance and mixture.
2. identify the types of mixture.
3. what does homogenous and heterogenous mean?
4. give the characteristics of solution.
5. what are the components of solution? give examples. ​

Sagot :

Explanation:

1. In chemistry: a pure substance consists only of one element or one compound. a mixture consists of two or more different substances, not chemically joined together.

2. Mixtures can be classified into three types: suspension mixture, colloidal mixture or solution.

3. In most technical applications homogeneous means that the properties of a system are the uniform throughout the entire system; heterogeneous (also inhomogeneous) means that the properties change within the system. ... For example, homogeneous systems have the same composition, density and pressure throughout.

4. Characteristics of Solutions

It is a homogeneous mixture.The size of solute particles in the solutions is extremely small. ...The particles of a solution cannot be seen even with a microscope.The particles of a solution pass through the filter paper. ...It is very stable.

5. Components of solutions

A solvent constitutes the larger component of the solution. For example, a solution of sugar in water is solid in the liquid. Here, sugar is the solute and water is the solvent. Solute: The component of the solution which dissolves in the solvent is called solute.
