100
Anything that has mass and takes up space.
What is matter?
100
Energy an object has because of its motion.
What is Kinetic Energy?
100
The smallest particle of an element that retains all the properties of that element.
What is an atom?
100
-Color Change -Odor change -Formation of a gas -Formation of a solid (precipitate) -Creation of heat -Creation of light
What are signs of a chemical reaction?
200
A characteristic of a substance that doesn’t involve a chemical change. This can be observed or measured without changing the matter’s identity.
What is a physical property?
200
Energy an object has because of its position, shape, or condition.
What is Potential Energy?
200
Metals, nonmetals, and metalloids.
What are the three major classes of elements?
200
One releases energy, the other kind absorbs it.
What is the difference between endothermic and exothermic reactions?
300
These describe a substance’s ability to participate in chemical reaction. This property of matter can only be observed during a change in the matter’s identity.
What is a chemical property?
300
Fahrenheit, Celsius, and Kelvin.
What are the three temperature scales?
300
Bonds that form between metals and nonmetals and forms when valence electrons are transferred.
What are Ionic Bonds?
300
Concentration, surface area, temperature, catalysts, and inhibitors.
What are things that affect the rate of a chemical reaction?
400
All matter is made up of atoms or groups of atoms (or molecules) and they are in constant motion.
What is the Kinetic Theory of Matter?
400
Wind energy, geothermal energy, and solar energy all fall under that category.
What are some kinds of renewable energy?
400
An atom that has an electric charge.
What is an Ion?
400
Biological catalysts that allow reactions to occur at body temperature.
What is an enzyme?
500
-Gravity/centrifuge- lets parts settle out -Filtration- filter traps larger sized particles -Magnetism- magnets can attract magnetic minerals -Evaporation- liquid portion evaporates leaving solids -Distillation- separate liquids with different boiling points, heat mixture up until one becomes gas, remove gas and allow to cool and become a liquid.
What are some ways you can separate mixtures?
500
Coal, Fossil Fuel, Natural Gas, and Nuclear Energy.
What are some different kinds of nonrenewable energy sources?
500
Ionic bonds, covalent bonds, and metallic bonds.
What are the three kinds of bonds?
500
A molecule made only of hydrogen and carbon.
What is a hydrocarbon?
