Question

zinc reacts with dihydrogen sulfide in a single replacement reaction. zn + h₂s → what are the products of this reaction? hzn + s zn₂s + h₂ zns + h₂ szn + h

Explanation:

Step1: Understand single - replacement reaction

In a single - replacement reaction \(A + BC
ightarrow AC + B\). Here \(A = Zn\), \(B = H\), \(C=S\).

Step2: Write the products

When \(Zn\) reacts with \(H_2S\) (where the formula of dihydrogen sulfide is \(H_2S\)), \(Zn\) replaces \(H\). The sulfide of \(Zn\) is \(ZnS\) (since \(Zn\) has a charge of \(+ 2\) and \(S\) has a charge of \(-2\), so the formula is \(ZnS\) by criss - cross method) and the displaced \(H\) atoms form \(H_2\) (because hydrogen is diatomic).

Answer:

\(ZnS + H_2\)
