Complete the exercises below. Write the chemical formula for each of the following, and indicate the oxidation state of the halogen or noble-gas atom in each: a. calcium hypobromite, b. bromic acid, c. xenon trioxide, d. perchlorate ion, e. iodous acid, f. iodine pentafluoride.

Oxidation states, or oxidation numbers, indicate the degree of oxidation of an atom in a compound. They help in understanding electron transfer during chemical reactions. The oxidation state is assigned based on a set of rules, such as the oxidation state of an element in its elemental form being zero, and the sum of oxidation states in a neutral compound being zero.

A chemical formula represents the composition of a compound, showing the types and numbers of atoms present. For example, in calcium hypobromite (Ca(BrO)2), the formula indicates one calcium atom, two bromine atoms, and two oxygen atoms. Understanding how to derive chemical formulas from names is essential for accurately identifying compounds and their properties.

Acids are substances that can donate protons (H+) in a solution, while bases can accept protons. The strength of an acid or base is determined by its ability to dissociate in water. For example, bromic acid (HBrO3) is a strong acid that dissociates completely in solution, affecting the oxidation states of its constituent elements and their behavior in reactions.
