Anything that has mass and takes up space.
What is matter?
100
This is the definition of "physical property."
What is "a characteristic of matter that can be observed or measured without changing the identity of the matter."
100
This is the definition of "physical change."
What is "a change in size, shape, form, or state in which the matter's identity stays the same."
100
This is the definition of chemical change.
What is "a change in which substances change into other substances with new physical and chemical properties"?
100
This is the formula for finding atomic mass.
What is the number of protons + number of neutrons?
200
This is the definition of an atom.
What is "a small particle that is a building block of matter."
200
This is the formula for density.
What is D=M/V?
200
This is deposition.
What is when matter skips from a state of gas to a solid without becoming a liquid?
200
These are three ways to increase the rate of a chemical reaction.
What are to increase the: temperature, concentration, or surface area?
300
The number of these always differs in atoms of different elements.
What are protons?
300
These are 5 of the 7 physical properties of matter listed in your textbook.
What are mass/conductivity/volume/boiling and melting point/density/solubility/magnetism?
300
This happens when thermal energy is added to a substance.
What is the particles get excited and start to move faster?
300
These are the 4 signs of a chemical change discussed in class.
What are bubbles, odor change, color change, and energy or temperature change?
300

These are examples of one: element, compound, and mixture.

400

This is the chemical formula for a compound with 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms.

What is C6H12O6 (use subscripts)

400
This is a physical property that usually can't be used to separate mixtures.
What is conductivity?
400
This substance has undergone sublimation in Mr Ewen's freezer.
What is water?
400
This is the definition of "concentration."
What is "the amount of a substance in a certain volume"?
400
These are two size-dependent physical properties.
What are mass and volume?
500

This is the difference between a heterogenous mixture and a homogenous mixture.

What is that a heterogenous mixture is unevenly mixed, while a homogenous mixture has different substances that can't be seen by the naked eye, such as solutions.

500
These are two size-independent properties of a matter.
What are density and melting point?
500
This is the law that led to our discussion of balancing equations in section 4, and its definition.
What is the Law of Conservation of Mass: "Matter is neither created nor destroyed"?
500
This is the balanced chemical equation for creation of starch from carbon dioxide and water during photosynthesis.
What is 6CO2 + 6H2O -> C6H12O6 + 6H2O?
500
This is a way to separate a mixture of sand, sugar, and water.
What is to filter the sand from the sugar/water mixture then to boil the mixture and leave the sugar behind?
