Answer: The chemical formula of ammonium sulfate is [tex](NH_4)_2SO_4[/tex]
Explanation:
Ammonium sulfate is a salt which is formed by the combination of two polyatomic ions which are ammonium and sulfate ions.
The chemical formula for ammonium ion is [tex]NH_4^+[/tex] and the chemical formula for sulfate ions is [tex]SO_4^{2-}[/tex]
By criss-cross method, the oxidation states of the ions becomes the subscripts of the other ions.
Hence, the chemical formula of ammonium sulfate is [tex](NH_4)_2SO_4[/tex]
