To predict the formula for unknown bromine oxide A in the given reaction. Concept introduction: An oxide of bromine BrO 2 is prepared by treating bromine with ozone. However, it was later observed that the heating of this oxide results in formation of two more oxides which can be identifed using reagents like sodium iodide and silver nitrate. The structure of these oxides can be either linear or bent.

Solution Summary: The author explains the formula for unknown bromine oxide A in the given reaction.
Definition Definition Connection between particles in a compound. Chemical bonds are the forces that hold the particles of a compound together. The stability of a chemical compound greatly depends on the nature and strength of the chemical bonding present in it. As the strength of the chemical bonding increases the stability of the compound also increases.

Lewis structures are diagrams that represent the chemical bonding of covalently bonded molecules and coordination compounds.
It is also known as Lewis dot structures which represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
Molecular geometry is the shape of a molecule predicted by considering only bond pair of electrons
According to VSEPR theory, the geometry is predicted by the minimizing the repulsions between electron-pairs in the bonds and lone-pairs of electrons. The VSEPR theory is summarized in the given table as,
Magnesium carbonate is soluble in water (100 mg / L) whereas strontium carbonate is only slightly soluble in water (11 mg / L). Would you expect barium carbonate to be more or less soluble than calcium carbonate? Why?
Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A−, B−, and C−ions, all of which are colorless. When a solution of C is mixed with one containing B− ions, the color changes from red to yellow.
Which species is oxidized? Which species is reduced?
When a solution of C is mixed with one containing A− ions, the color remains red. Is C a better oxidizing agent than A? Or it is a better oxidizing agent than B?
Arrange A, B, and C in order of increasing strength as an oxidizing agent.
