Reaction Types Flashcards
reactions where two or more reactants form one product
combination reaction
Where a compound breaks down into two or more substances, usually as a result of heating or electrolysis
decomposition
A specific process that causes the decomposition of a compound by passing an electric current through the reactant
electrolysis
Reactions where an atom or ion of one compound is replaced by an atom of another element
single-replacement
reaction written so that only the species that participate in the reaction are shown; no spectator ions
net ionic reaction
In double displacement reactions also called __ ___, elements from two different compounds ___ each other to form two new compounds, This type of reaction occurs when one of the products is removed from the solution as a ___ or ____, or when two of the original species combine to form a _ ____ that remains ____ in solution
metathesis reactions, displace, precipitate, gas, weak electrolyte, undissociated
Specific type of double replacement that occurs when an acid reacts with a base to produce salt and water
neutralization reaction
Reaction involving the transfer of electrons from one species to another
oxidation reduction reaction
The number of charges an atom would have in a molecule if electrons were completely transferred in the direction indicated by the difference in electronegativity
oxidation number
The oxidation number of a free element is ____. The oxidation number for a ___ ___ is equal to the charge of the ion.
0, monoatomic ion
The oxidation number for each group in group 1A is ____ and in 2A is ___. The oxidation number of each halogen is ____, except when combined with an element of higher ____.
+1, +2, -1, electronegativity
The oxidation number of hydrogen is generally ___. However, the oxidation number can be ___ when H is placed with groups __ and ___, in other words, less electronegative elements.
+1, -1, 1A, 2A
In most compounds, the oxidation number of oxygen is ___. In elements that are more electronegative, its state is ____. In _____ the oxidation number is ___.
-2, +2, peroxides, -1
The sum of the oxidation numbers of all the atoms present in a neutral compound is ___. The sum of the oxidation numbers of the atoms present in a __ __ is equal to the charge of the ion
0, polyatomic ion
Fluorine has an oxidation number of ___ in all compounds because it has the ___ ___ of all the elements,
-1, highest electronegativity
___ elements only have positive oxidation numbers, however, ____ elements may have a positive or negative oxidation number
metallic, nonmetallic
To balance a redox reaction in an acidic solution, separate the two ____, and balance the atoms of each except __ and ___. Next, add ___ to balance the O atoms and ___ to balance the H atoms. Then balance the ____ of each half reactions. Then combine the half reactions, making sure they have the same number of electrons that will ___ each other out. Simplify the final equation
half-reactions, H, O, H2O, H+, electrons, cancel
To balance a basic redox reaction, do the same as the acidic, then add _____ to neutralize the added H+ This is because in a basic solution ___ should not appear as a ___ since it is not readily ___. Then combine the added H and OH into ____. Simplify the final equation
OH-, H+ reactant, available, water
