Science - CLASSIFICATION OF MATTER

Can you separate this item by physical means? (E.g temp, filter, density, spinning) if yes, it is a:

Mixture

How many phases in a mixture?

2 or more

If a mixture is uniform, is it homogeneous or heterogeneous

Homogenous

If a mixture is NOT uniform, is it heterogeneous or homogeneous?

Heterogeneous

What are the 2 types of homogeneous?

Solution, suspension

What is one type of heterogeneous?

Mechanical mixture

What’s a solute

a substance that can be dissolved into a solution by a solvent.

What’s a solution

a mixture of substances that are evenly mixed

What’s this

Solution

What’s a solvent

a substance that dissolves a solute, resulting in a solution.

Does solute have more or less substance?

has less % of a substance than a solvent in a solution.

Solute example

Salt, sugar

Does solvent have more or less substance?

Has more % of a substance than solute in a solution.

Example of solvent

Alcohol, water

What is a suspension?

Only separates by spinning

Examples of suspensions:

Laundry detergent, milk

What is a mechanical mixture?

A mechanical mixture cannot be mixed to form another substance.

Examples of mechanical mixtures

Sand + water, oil + water

What does m=

Slope

What is mass over?

Volume

Do you divide by mass or volume

Mass / volume

Solve image

10 - 5=5, 6-4=2, 5/2 = 2.5 g/m3

What’s the temps true when the time reaches 700?

60

What’s this

What does density equal

Mass/volume

What’s this

Erlenmeyer flask
