Covalent Bonds
A molecule that is formed when its outermost electrons are shared.
What is a covalent molecule?
Binary acids contain these.
What is hydrogen and one other element?
This bond is formed by a force that holds oppositely charged particles together.
What is an ionic bond?
R1 + R2 -----> P1 + P2
What is a chemical equation?
A + B ----> AB
What is a synthesis reaction?
These types of atoms form the majority of covalent bonds.
What are nonmetallic atoms?
The first word of a binary acid that is a prefix denoting hydrogen.
What is -hydro?
Its properties tend to be soft and flexible and do not conduct electricity.
What are covalent bonds?
In a chemical reaction, matter can neither be created nor destroyed,
What is the Law of the Conservation of Mass?
When this is present with O2, the products are always CO2 and H2O.
What is a hydrocarbon?
These prefer to exist together because they find more stability that way.
What are diatomic molecules?
An acid that contains both a hydrogen ion and an oxyanion.
What is an oxyacid?
This property is dependent upon free flowing ions in the liquid or molten state but not solid.
What is conductivity?
When balancing a chemical equation, this can never be changed.
What are subscripts?

What is a double displacement reaction?
A single covalent bond is known as this.
What is a sigma bond?
An oxyanion whose name ends in -ate will change its suffix to this in naming an oxyacid.
What is -ic?
They have strong intra-molecular forces that are nonpolar and are the same atom.
What is a truely (or nonpolar) covalent bond?
Coefficients are written in this manner.

The amount of energy required to break a specific covalent bond.
What is bond-dissociation energy?
The name of this oxyacid. HClO3
What is chloric acid?
Its boiling points are determined by weak inter-molecular forces known as Van der Waal forces.
