100
Mass of the atom
What is the nucleus?
100
Classification of elements along the stairstep line
What are metalloids? (metals to the left, nonmetals to the right)
100
Chemical reaction producing carbon dioxide and water
What is combustion? (remember these are all listed in the reference materials)
100
The part that is in the greater amount in a solution
What is the solvent? (can be any state of matter)
100
Ions produced by a base
What are hydroxide ions? (Acid = H+, base = OH-)
200
Number of electrons in an electrically neutral atom of carbon.
What is 6? (Protons = Electrons when neutral)
200
Highest for ionization energy
What is Helium? (electronegativity is F, atomic radius is Fr)
200
Numbers that represent the number of atoms in a given formula
What are subscripts? (Subscripts are found using the prefixes for covalent, the charges for ionic)
200
Solution with sour taste and pH of 5
What is acid? (review properties of acids and bases)
200
Used to lower the activation energy but not to change the reaction
What are catalysts? (can speed up the reaction)
300
Ion formed by losing electrons.
What is cation? (Anions are negative from gaining electrons. Cations left side of table, anions right)
300
Valence electrons can be determined this way
What is group number? (for representative element groups only)
300
Numbers used to balance chemical reactions in order to abide by the Law of Conservation of Matter
What are coefficients? (Coefficients can also be used to make mole ratios)
300
Solubility of this state of matter increases with decreasing temperature
What are gases? (solid in liquid dissolves more at higher temperatures where gas in liquid dissolves more at lower temperatures)
300
Solid formed when two solutions are mixed and can indicate a chemical reaction has taken place
What is precipitate? (solubility rules to determine if a precipitate will form are in the reference materials)
400
Used to determine protons and order the elements on the table
What is atomic number? (Represented by the symbol Z)
400
Charge on alkaline earth metals
What is +2? (memorize the group charges on the table)
400
In order to convert from grams to moles you must first calculate this
What is the molar mass? (remember the molar mass is the mass given on the table multiplied by the subscript)
400
Using the molarity and volume of a known base to determine the molarity of an unknown acid
What is a titration? (review indicators such as phenolpthelein which is pink for bases)
400
Relationship between pressure and volume
What is inverse? (use the combined gas law in the reference materials to determine all gas law problems)
500
If magnesium-24 was to undergo alpha radiation this is the result.
What is neon-20? (Alpha radiation is the release of a helium particle so the atomic number decreases by 2 and the mass by 4)
500
Group that is most stable due to complete octets
What are noble gases? (they are INERT - unreactive)
500
A chemical reaction with the energy of the products lower than the energy of the reactants
What is exothermic? (Exo, low products, hot... Endo, high products, cold)
500
Properties of solutions that can change due to the amount of solute added
What are colligative properties? (BP elevation, FP depression, vapor pressure lowering)
500
A change that can sometimes be chemical but also could be physical
What is color change? (mixing is just physical but color can indicate chemical, remember bubbles forming can be chemical as well, unless it is just the release of gas from a solution, which would be physical)
