Chemistry Introduction
It is the study of matter, its properties, how it behaves, how it is put together, and how it can be changed or rearranged
What is Chemistry?
Matter is defined as
Anything that has weight and take up space; anything that has mass and volume
What is the particle molecular theory of matter?
What all matter is made up of.
What is "small particles known as atoms"?
Out of the three common states of matter, the one with the most energy.
Whas is gas?
Give 2 examples of chemistry in everyday life
- Food
- Cleansing Agents
- Cosmetics
- Elements of the Body
The measure of how much space an object takes up.
What is Volume?
The number of assumptions made for the particulate theory of matter?
What is 5?
What pure substances have.
What are unique or specific particles?
State of matter where particles have enough energy for freedom of motion with no definite shape, as well as to spread out with no definite volume.
What is gas?
The number of branches of chemistry.
Give 3 examples of things that are NOT matter.
What are:
- gravity
- time
- love
- energy
- sound
- heat
It is the basic building block of matter.
What is an Atom?
True or False: particles attract each other and do not have spaces between them.
What is False?
Particles vibrate in a fixed position, has a fixed shape and the rate of diffusion is very low.
What is Solid?
What is "biochemistry"?
What is "biochemistry is the study of chemical substances and processes that occur in living things?"
What is False?
What are electrons, neutrons, and protons?
The assumptions proven based on the experiment done in class with the diffusion of potassium manganate.
- All particles are constantly in motion
- As temperature increases, particles of matter move faster
- Particles attract each other and have spaces between them
Describe the particle arrangement for Liquids. Draw a diagram as well.
Particles are close together with no fixed pattern, can move and slide past each other, fixed volume but no fixed shape, IMF is intermediate
The branch of chemistry responsible for studying compounds such as salts and minerals.
What is inorganic chemistry?
The measure of the amount of matter an object has; it depends completely on the molecules an object is made of.
What is mass?
The name given to the three particles that collectively make up an atom.
The name of the experiment that was made popular to help bring evidence in support of the particulate theory of matter
What is the reaction between Ammonia and Hydrochloric Acid?
Rank the states of matter from highest kinetic energy to lowest kinetic energy.
What is gas --> liquid --> solid
