Q6
銅與稀硝酸反應後，打開試管口可見有紅棕色氣體。這與以下哪一個反應有關？
$\ \ 2\ \mathrm{N}\mathrm{O}_{(g)}+\mathrm{O}_{2(g)}\longrightarrow\mathrm{2\ N}\mathrm{O}_{2(g)}\ \$
$\mathrm{N}\mathrm{O}_{2(g)}\ \ \longrightarrow\ \ \mathrm{N}_2\mathrm{O}_{4(g)}$
$\mathrm{Cu}_{(s)}+4\ \mathrm{H}\mathrm{N}\mathrm{O}_{3(aq)}\ \ \longrightarrow\ \ \mathrm{\mathrm{Cu}\left(NO_3\right)_{2(aq)}}+2\ \mathrm{N}\mathrm{O}_{2(g)}+2\mathrm{\ H}_2\mathrm{O}_{(l)}$
$\mathrm{3\ Cu}_{(s)}+8\ \mathrm{H}\mathrm{N}\mathrm{O}_{3(aq)}\ \ \longrightarrow\ \ \mathrm{3\ Cu}\left(\mathrm{N}\mathrm{O}_3\right)_{2(aq)}+\mathrm{2\ N}\mathrm{O_{(g)}}+\mathrm{4\ H}_2\mathrm{O}_{(l)}$
