which formula equation shows a reversible reaction?\n2na + f₂ → 2naf\ncaco₃ → cao + co₂\nnh₄cl(s) ⇌ nh₃(g) + hcl(g)\n2h₂o₂(aq) xrightarrow{n}2h₂o(l) + o₂(g)

which formula equation shows a reversible reaction?\n2na + f₂ → 2naf\ncaco₃ → cao + co₂\nnh₄cl(s) ⇌ nh₃(g) + hcl(g)\n2h₂o₂(aq) xrightarrow{n}2h₂o(l) + o₂(g)

Answer

Brief Explanations:

A reversible reaction is indicated by a double - headed arrow ($\leftrightarrow$). In the given options, only the reaction $NH_{4}Cl(s)\leftrightarrow NH_{3}(g)+HCl(g)$ has a double - headed arrow, showing that the reaction can proceed in both the forward and reverse directions.

Answer:

$NH_{4}Cl(s)\leftrightarrow NH_{3}(g)+HCl(g)$
