ightarrow 2 \mathrm{H}_{2} \mathrm{O}_{(1)}+3 \mathrm{~S}_{(\mathrm{s})}\)
B. \(\mathrm{H}_{2} \mathrm{O}_{(\mathrm{s})}
ightarrow \mathrm{H}_{2} \mathrm{O}_{(\mathrm{l})}\)
C. \(\mathrm{N}_{(9)}+3 \mathrm{H}_{2(g)}
ightarrow 2 \mathrm{NH}_{3(g)}\)
D. \(\mathrm{Cu}_{(\mathrm{aq})}^{2+}+\mathrm{Fe}_{(\mathrm{s})}
