Problem 63a

Chapter 7, Problem 63a

Chlorine reacts with oxygen to form Cl2O7. (a) What is the name of this product (see Table 2.6)?

Verified step by step guidance

Identify the type of compound formed by chlorine and oxygen.

Recognize that Cl2O7 is a molecular compound composed of nonmetals.

Use the rules for naming binary molecular compounds: the first element is named first, and the second element is named as if it were an anion.

For the second element, use the root of the element name and add the suffix '-ide'.

Use prefixes to indicate the number of atoms of each element: 'di-' for two chlorine atoms and 'hepta-' for seven oxygen atoms.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Chemical Nomenclature

Chemical nomenclature is the system of naming chemical compounds based on their composition and structure. It follows specific rules set by organizations like the International Union of Pure and Applied Chemistry (IUPAC). Understanding nomenclature helps in identifying compounds and their properties, which is essential for answering questions about chemical reactions.

Oxides

Oxides are compounds formed when elements react with oxygen. They can be classified into various types, such as metal oxides and non-metal oxides, depending on the elements involved. In this case, Cl2O7 is a non-metal oxide, specifically a dichlorine heptoxide, which is important for understanding the nature of the product formed in the reaction.

Stoichiometry

Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in a chemical reaction. It allows chemists to predict the amounts of substances consumed and produced in a reaction. While the question focuses on naming the product, understanding stoichiometry is crucial for grasping the overall reaction dynamics and the significance of the compound formed.
