Question

Решите цепочку: Н2О→О2→ZnO→Zn→H2→H2S→SO2.​

Answer 1

2H2O -> 2H2 + O2

2Zn + O2 -> 2ZnO

ZnO + CO -> Zn + CO2

Zn + 2HCI -> ZnCl2 + H2

H2 + S -> H2S

2H2S + 3O2 -> 2H2O + 2SO2

Answer 2

$H_{2}O = O_{2} + 2H_{2} \\ </p><p>2Zn + O_{2} = 2ZnO \\ </p><p>ZnO + H_{2} = Zn + H_{2}O \\ </p><p>Zn + H_{2}O = Zn(OH)_{2} + H_{2} \\ </p><p>2H_{2} + S_{2} = 2H_{2}S \\ </p><p>2H_{2}S + 3O_{2} = 2SO_{2} + 2H_{2}O$
