Question 19

What are Matter and Atoms

Answer 19

Matter is anything with mass and volume
Atoms are the building blocks of matter

Question 20

Different types of atoms are called

A group of 2 or more atoms bonded together

Question 22

A compound is

Answer 22

a molecule with 2 or more different atoms/elements bonded together

Question 23

A mixture is a

Answer 23

material made up of 2 or more substances

Question 24

What are the Properties of Mixtures

Answer 24

1. Made of More than one type of Particle
2. The ratio of the different types of particles can vary
3. The properties of the Mixture are a synthesis of the properties of each substance

Question 25

What is a pure substance

Answer 25

A substance with a fixed ratio and anything made with one type of particle

Question 26

Mixtures are a combination of

pure substances that not chemically joined

Question 27

2 types of Mixtures are

Answer 27

Heterogeneous with vary in composition Homogeneous which have the same composition and when they are in a liquid are called solutions

Question 28

All mater is composed of

Answer 28

tiny particles that are in motion and transfer KE when they collide

Question 31

Density is the amount of

Answer 31

Mass per unit volume

Question 32

What is the Density Formula

Answer 32

Density = Mass/Volume Volume is measured in mL or cm cubed

Question 33

characteristic of a substance that can only be viewed when there is change

Question 37

Some examples of chemical properties are

Answer 37

burning, tarnishing, rusting, and decomposing

Question 38

What is a physical change

Answer 38

Changes the form or appearance not the type of substance

Question 39

4 signs of Physical changes are

Answer 39

the state of matter, often reversible, changes shape, no new substance is made

Question 40

A chemical change is when
