100

What determines the physical properties of matter?

The arrangement of atoms

100

100

Chemical equations are used to describe me 

chemical changes or chemical reactions

200
What is the difference between a hetergeneous mixture and a homogeneous mixture?
A heterogeneous is a type of mixture in which the individual substances are not evenly mixed. A homogeneous is a type of mixture in which the individual substances are evenly mixed.
200
How are elements related to compounds?
Each compound is made of atoms of two or more different elements chemically bonded together.
200

What are the three states of matter?

Solid, Liquid, Gas

200
What is deposition?
Deposition occurs when a gas changes into a solid without first becoming a liquid.
200

iron filings and sand can be separated by this physical property

magnetism

300
What is the difference between a physical property and a chemical property?
A physical property is a characteristic of matter that you can observe or measure without changing the identity of the matter. A chemical property is a characteristic of matter that can be observed as it changes to a different type of matter.
300
Describe the electrical charges of the particles in atoms?
Protons have a positive charge. Neutrons have no change. Electrons have a negative charge.
300

What determines the state of matter?

How close the particles are to one another in the matter and how fast they move.

300
What is sublimation?
Sublimation occurs when a solid changes directly into a gas without first becoming a liquid.
300

Color change, odor change, and bubbles are signs that what might have occurred. 

chemical change

400
Why is a physical change different than a chemical change?
The matter from a physical change stays the same and the matter from a chemical change tends to change into other substances with new physical and chemical properties.
400

Compare a solvent and a solute?

The solvent has greater quantity and does the dissolving. The solute is in smaller amounts and is what gets dissolved

400

What determines if a property is size-dependent?

A property is size-dependent if its value depends on the size of a sample?

400
What is the boiling point of matter?
The temperature at which a liquid changes into a solid.
400

What activity could be a sign that a chemical change has occurred? A) a solid melts B) a substance dissolves C) a liquid changes color D) an object change shape

C) a liquid changes color

500
What are the two characteristics of matter?
Substances and mixtures
500

What can you learn about a compound from its chemical formula?

You can determine the different atoms that make up compound. You also can determine how the atoms combine.

500

What change of state occurs when a substance reaches its melting point? What occurs when it reaches its boiling point?

A substance changes from a solid to a liquid when it reaches its melting point. It changes from a liquid to a gas when it reaches its boiling point.

500
Describe the movement of particles when thermal energy is added to a solid?
The particles speed up and move farther apart.
500
