Final answer:
The question involves writing chemical formulas and formation equations for various named compounds, such as ferrous sulfite (FeSO3) and aluminum hydroxide (Al(OH)3).
Step-by-step explanation:
The subject of this question primarily deals with writing the chemical formulas and formation equations for various compounds in chemistry.
For instance:
Ferrous sulfite is composed of the ferrous ion (Fe2+) and sulfite ion (SO32-), and its formula is FeSO3.
Aluminum hydroxide involves the aluminum ion (Al3+) and hydroxide ion (OH-), yielding the formula Al(OH)3.
Periodic acid has the formula HIO4.
