(H) Chemical Bonding and Equations Review

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

Front

What is the difference between a coefficient and a subscript in a chemical equation?

Back

A coefficient indicates the number of molecules, while a subscript indicates the number of atoms of an element in a molecule.

Front

What type of reaction is represented by the equation Pb(NO3)2 → PbO + NO2 + O2?

Back

Decomposition reaction.

Front

What do electrons do in a metallic bond?

Back

They float around freely, creating a 'sea of electrons' that allows metals to conduct electricity.

Front

What elements generally form an ionic bond?

Back

A metal and a nonmetal.

Front

Predict the bond that will form between Na (metal) and Cl (nonmetal).

Back

Ionic bond.

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

What is the main characteristic of a metallic bond?

Back

Metallic bonds are characterized by a 'sea of electrons' that are free to move around, allowing metals to conduct electricity.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.
