Particle Theory
What are the 3 states of matter?
Solid, liquid, and gas.
Name 3 types of physical properties.
Colour, state, malleability, hardness, viscosity, optical clarity, etc.
What is a Physical Change?
When the object changes shape, texture, temperature, or state
The periodic table displays what basic building blocks?
Elements
What is a mixture?
when there are 2 or more different kinds of particles in a substance.
Which state of matter is highest in energy?
Gas
Name 3 types of chemical properties
Reactivity in water, reactivity in air, reactivity in heat, combustion, etc.
State an example of a physical change.
Anything that I deem correct.
It is most reactive in this area.

Chocolate chip cookies. Pure or mixture

What are the 4 parts of the particle theory?
1. All things are made of particles
2. There is space between
3. Always moving
4. More energy increases space, and movement.
Describe 2 physical properties, and 1 chemical property of water.
What I deem correct.
What is a chemical reaction?
Particle move around and a new substance is formed.
It is least reactive in this area

What is a pure substance?
When there is only one kind of particle in a substance.
Using particle theory, how does a solid turn to a liquid.
The increase in energy, increases movement and space. Allowing for particles to move my each other.
Name 2 physical properties of wood, and 1 chemical property.
What I deem correct.
State an example of a chemical reaction. What evidence was there to say it was a chemical reaction? (think of what we did in class)
Anything I deem correct.
Looking at the periodic table, what is the most reactive element?
Francium or Fr
Distilled water. Pure or mixture
Pure
Using particle theory, explain how a gas goes to a liquid.
Decrease in energy, decreases movement, and space, causing particles to move closer, and not move past each other, but glide past each other.
Name 2 physical properties and 1 chemical property of copper.
What I deem correct.
Mixing a red fluid with a white fluid. We get a pink fluid. Is this a chemical reaction? Why?
No, it is now a mixture. It is not a new colour, it is what we get when we mix red and white.
What is the name of the non reactive group.
Noble Gases
A rusty nail. Pure or mixture?
Mixture
