Answer: The chemical formula of ammonium sulfate is \((NH_4)_2SO_4\)
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 \(NH_4^+\) and the chemical formula for sulfate ions is \(SO_4^{2-}\)
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 \((NH_4)_2SO_4\)
