Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is the formula for dinitrogen pentoxide?

Back

N2O5

Front

How do you determine the chemical formula for magnesium chloride?

Back

Magnesium has a charge of +2 (Mg^2+) and chloride has a charge of -1 (Cl^-). To balance the charges, two chloride ions are needed, resulting in MgCl2.

Front

What is the name of the compound with the formula CuSO4?

Back

Copper(II) sulfate.

Front

Explain how to write the formula for calcium hydroxide.

Back

Identify calcium as Ca^2+ and hydroxide as OH^-. To balance the charges, you need two hydroxide ions, resulting in Ca(OH)2.

Front

What is the correct name for FeCl3?

Back

Iron(III) chloride.

Front

What is the significance of the Roman numeral in copper(II) sulfate?

Back

The Roman numeral indicates the oxidation state of the copper ion, which is +2 in this case.

Front

What is the difference between a molecular compound and an ionic compound?

Back

Molecular compounds consist of molecules formed by covalent bonds, while ionic compounds consist of ions held together by ionic bonds.

Front

How do you name a binary ionic compound?

Back

The name of a binary ionic compound consists of the name of the cation followed by the name of the anion, with the anion's name ending in '-ide'.
