_____ is the study of the composition of matter and the changes that matter undergoes.
What is Chemistry?
100

These types of matter can be physically separated, not chemically separated.

What are mixtures.

Compounds must be chemically separated, not physically separated.

100
is a characteristic of a substance that can be observed or measured without changing the identity of the substance.
What is Physical Property
100
is a physical blend of two or more components, each of which retains its own identity and properties
What is Mixture?
100

describes the ability of a substance to undergo a chemical change.

What is Chemical Property?

200

Elements are made up of these small particles

What are atoms

200

In this phase change a solid changes directly into a gas.  Like dry ice (solid carbon dioxide)

sublimation

200

Carbon dioxide, water, sodium chloride are all examples of a

What is Homogeneous?
200
a process that occurs when one or more substances are changed into one or more new substances
What is Chemical Reaction?
300

This is the amount of matter or stuff in an object

What is mass

300

This law states that the mass of the reactants and the mass of the products is the same in a chemical reaction.

300
solid, liquid, and gas are?
What is States of Matter
300

a method of separating a mixture based on differences in size of the particles (like sand and water)

What is Element
400

Name the 2 types of mixtures and give an example of each.

Homogeneous - solution, salt water

Heterogeneous - sand and water

400

Density is an extensive property.  True or False

False, density does not change based on the size of the sample

400

is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not.

What is Physical Change

400
a pure substance containing two or more elements that have been chemically combined in a fixed proportion.
What is Compound?
400

Name 3 things that tell you that a chemical change probably occurred.

What is change in color, temperature, formation of a gas, light, noise, formation of a precipitate

500

Matter can be separated into these 2 types of PURE substances

What are elements and compounds

500
a solid product that forms from a reaction and settles out of a liquid mixture.
What is precipitate?
