Chapter 2 REACTIONS AND PERIODICITY

Nonelectrolytes substances

________ that do not conduct an electrical current when dissolved in water.

Single displacement

________ (replacement) reactions are reactions in which atoms of an element replace the atoms of another element in a compound.

acceptors

Bases are defined as proton ________ or electron- pair donors.

Redox

________ is a term that stands for reduction and oxidation.

Reduction

________ is the gain of electrons, and oxidation is the loss of electrons.

universal solvent

Water is called the ________, because it dissolves so many substances.

Law of Conservation

________ of Matter, which says that in ordinary chemical reactions matter is neither created nor destroyed.

coordination compounds

In reactions involving ________, the metal acts as the Lewis acid, while the ligand acts as a Lewis base.

Combustion reactions

________ are redox reactions in which the chemical species rapidly combines with oxygen and usually emits heat and light.

equivalence point

The ________ is that point in the titration where the number of moles of H+ in the acid solution has been exactly neutralized with the same number of moles of OH- Common Mistakes to Avoid.

insoluble product

If at least one ________ is formed, the reaction is classified as a double displacement (replacement) or metathesis reaction.

Acids

________ are defined as proton donors or electron- pair acceptors.

Ions

________ can attract the polar water molecules and form a bound layer of water molecules around themselves.

Coordinate covalent bonds

________ are covalent bonds in which one of the atoms furnishes both of the electrons for the bond.

chemical equation

Balancing the ________ shows which chemical species are the reactants and which species are the products.

titration

A(n) ________ is a laboratory procedure in which a solution of known concentration is used to determine the concentration of an unknown solution.

Decomposition reactions

________ are reactions in which a compound breaks down into two or more simpler substances.

complex ion

A(n) ________ is composed of a metal ion bonded to two or more molecules or ions called ligands.

Single Displacement

Electrolysis, in which an electrical current is used to decompose a compound into its elements: ________ Reactions.

Acids

________ react with bases to form a salt and, usually, water.

Ions

________ which are not actually involved in the chemical reaction taking places are called spectator ________.

Acids

________ and bases may be strong, dissociating completely, or weak, partially dissociating and forming an equilibrium system Acid- Base Reactions.

Ionic

________ compounds that dissolve in water (dissociate) form electrolyte solutions, which conduct electrical current owing to the presence of ions.
