The compound barium perchlorate forms a hydrate with three water molecules per formula unit. The name of hydrate and its formula is to be written. Concept introduction: Some chemical compounds on crystallization from water solution produce a crystal that contains water molecules as a part of their crystal structure. These water molecules of the crystals are called as water of crystallization or water of hydration. The crystal that results from the process of crystallization is referred as hydrate. Conversely, the water molecules can be driven away from the crystals by applying heat energy to afford anhydrous chemical compounds. The well-known example of a compound having water crystallization is CuSO 4 .5H 2 O. The anhydrous chemical compound CuSO 4 (colorless) is combined with 5 H 2 O molecules on crystallization from a water solution result in hydrated CuSO 4 .5H 2 O (blue). The name of this chemical compound is denoted as copper (II) sulfate penta hydrate. In this case, the prefix ‘penta’ is usually referred as the presence of 5 molecules (water).

What is the formula for iron(III) sulfide

Ions that form from one atom on the Periodic Table are call monatomic ions. However not all ionic bonds are formed with monatomic ions, polyatomic ions can form ionic bonds as well. The prefix poly- means many and atomic refers to atoms, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include Na+, Fe3+, Cl-, and many, many others. We can think about polyatomic ions by comparing them to monatomic ions. A monatomic ion is an atom that has been ionized by gaining or losing electrons. The ion has a net charge because the total number of electrons is not balanced by the total number of protons in the nucleus. Thus, compared to the neutral atom, we have extra electrons—in the case of a negatively charged anion—or not enough electrons—in the case of a positively charged cation. For example, a neutral chlorine atom has an atomic number of 17, which means it has 17…
