Acids/Bases
Metal Properties
Chem Numbers
Reactions
100
The scale on which acids and bases are measured.
What is pH?
100
When two metals are melded together, but no reaction has taken place to change the substances, it is known as this.
What is an alloy.
100
An amount of a substance (in atoms or molecules), equal to the number of atoms in 12 g of Carbon is called this.
What is a mole?
100
Metals become this type of ion. I'm positive.
What is a cation.
200
If a substance has a pH rating of 3, we would consider it to be this.
What is acidic?
200
Metals tend to have few of these, and frequently lose them in chemical reactions.
What are valence electrons?
200
The amount of mass in one mole of a substance is called this.
What is molar mass?
200
Sulfides and Oxides are examples of these types of ion. Don't be so negative!
What is an anion?
300
If a substance has a pH of 7, it would be considered this.
What is neutral?
300
This is the alloy of copper and zinc. (Remember the pennies)
What is brass?
300
6.022 x 10^23 number of atoms or molecules is considered a mole.
What is Avogadro's Number (or Constant)?
300
When 2 substances switch "partners" in a chemical reaction, it is called this.
What is a double-replacement reaction?
400
Acids exist when this ion is present.
What is Hydrogen? (H+)
400
Iron (or steel) heated to red hot and cooled quickly will become this.
What is hardened.

58.44 g
400
What will the products be of this double-replacement reaction? silver nitrate + potassium carbonate →
silver carbonate + potassium nitrate
500
What ion is present to make a substance be considered a base?
What is hydroxide? (OH-)
500
Iron (or steel) that is heated to red hot and allowed to cool slowly will become this.
What is annealed?
