Question

Which of the following equations represents a redox reaction?

Accepted Answer

$2H_{2}S_{(s)} + SO_{{2}{(g)}} \to 2HO_{2} + 3S_{(g)}$

Answer

$HNO_{{3}{(aq)}} + NaOH_{(aq)} \to NaNO_{{3}{(aq)}} + H_{2}O_{(l)}$

Answer

$AgNO_{{3}{(aq)}}+KCl_{(aq)} \to AgCl_{(s)}+KNO_{{3}{(aq)}}$

Answer

$CaCO_{{3}{(s)}} \to CaO_{(s)} + CO_{{2}{(g)}}$
