H2Se + Cr(OH)3................+ H2O
H2Te + Au(OH)3...............+H2O
H2Se + Tl(OH)................+ H2O
HI + Nb(OH)3..............+ H2O
GRACIAS

Answer 1

 

H2S + Mn(OH)3................+ H2O

3 H2S + 2 Mn(OH)3 →Mn2S3 + 6 H2O

H2Se + Cr(OH)3................+ H2O

3 H2Se + 2 Cr(OH)3 →Cr2Se3 + 6 H2O

H2Te + Au(OH)3...............+H2O

3 H2Te + 2 Au(OH)3 →Au2Te3 + 6 H2O

H2Se + Tl(OH)................+ H2O

H2Se + 2 Tl(OH) →Tl2Se + 2 H2O

HI + Nb(OH)3..............+ H2O

3 HI + Nb(OH)3 → NbI3 + 3 H2O
