Question

the chemical reaction in which ammonium sulfate and potassium hydroxide are mixed together is called
a double - replacement
b synthesis
c decomposition
d combustion reaction
e single - replacement

Explanation:

In a double - replacement reaction, the positive and negative ions of two ionic compounds exchange places. Ammonium sulfate \((NH_4)_2SO_4\) and potassium hydroxide \(KOH\) are both ionic compounds. When they react, the \(NH_4^+\) and \(K^+\) ions will exchange places with the \(OH^-\) and \(SO_4^{2 - }\) ions respectively.

Answer:

A. double - replacement
