Properties
The ability for one substance to be dissolved in another substance.
Solubility
Anything that has mass or takes up space.
Matter
What is the most basic building block of all matter?
Atom
What are unique characteristics that help identify a substance and helps tell one substance from another.
Properties
How many elements in H2O?
2 - Hydrogen and Oxygen
The temperature at which a substance melts.
Melting Point
The starting substances in a chemical reaction.
Reactants
What is a bunch of molecules that are bonded (stuck) together?
Molecule
True or False - The properties of a substance are always the same, no matter how much of the substance there is.
True
How many molecules in 3H2O2?
3
How hard a substance is compared to another substance.
Relative hardness
The final substances in a chemical reaction.
Products
A type of system where matter cannot be shared with its surroundings?
Closed System
What do we call it when the atoms of starting substances reactants) rearrange to form final substances (products)?
Chemical Reaction
How many atoms in NH3?
4
True of False - Mass and volume are properties of a subsatnce
False
What is made from only one material (atoms or molecules) all the way through?
Substance
A type of system where matter can be shared with its surroundings?
Open System
True or False - A phase change (example water evaporating into a gas) is a chemical reaction.
False

8
The property that can be calculated by dividing mass by volume (mass/volume).
Density
What is made up of more than one substance?
Mixture
A solid that forms during a chemical reaction
Precipitate
Atoms cannot be created or destroyed. in a chemical reaction, the number of atoms stay the same therefore what is conserved?
Matter?Mass
