Question

Цепочка: S>Al2S3>H2S>CUS>SO2>SO3

Answer 1

3S + 2Al -----> Al2S3
Al2S3 + 6H2O ------> 2Al(OH)3 + 3H2S
H2Cu + O3 -----> CuO2 + H2O
2SO2 + O2 -----> 2SO3
SO3 + 2NaOH ------> Na2SO4 + H2O

Answer 2

1. 3S+2Al=Al2S3

2. Al2S3+6HCl=3H2S+2AlCl3

3. H2S+Cu(OH)2=CuS+2H2O

4. CuS+?

5. 2SO2+O2=2SO3
