Complete the exercises below. Give the chemical formula for: a. carbonic acid, b. sodium cyanide, c. potassium hydrogen carbonate, d. acetylene, e. iron pentacarbonyl.

Chemical nomenclature is the system of naming chemical compounds based on their composition and structure. It follows specific rules set by organizations like IUPAC, which help in identifying the elements present and their arrangement. Understanding nomenclature is essential for translating names into chemical formulas and vice versa.

Acids are substances that can donate protons (H+) in a solution, while bases can accept protons. Carbonic acid, for example, is a weak acid formed from carbon dioxide and water. Recognizing the properties of acids and bases is crucial for identifying their chemical formulas and understanding their behavior in reactions.

Coordination compounds consist of a central metal atom bonded to surrounding molecules or ions called ligands. Iron pentacarbonyl is an example where iron is coordinated to five carbon monoxide ligands. Understanding the structure and bonding in coordination compounds is important for writing their chemical formulas accurately.
