Question

2н, +0,= 2H,0;Ж) 2Al + 3S = Al2S3​

Answer 1

Ответ:

Al (s) + 3 S (s) → Al2S3 (s)

Это окислительно-восстановительная (редокс) реакция:

3 S0 + 6 e- → 3 S-II(восстановле́ние)

2 Al0 - 6 e- → 2 AlIII(окисление)

S является окислителем, Al является восстановителем.

Answer 2

The equations you've provided appear to be chemical reactions. Let's balance them:

1. 2H2 + O2 → 2H2O This is the balanced equation for the reaction between hydrogen (H2) and oxygen (O2) to form water (H2O). It's already balanced.

2. 2Al + 3S → Al2S3 This is the balanced equation for the reaction between aluminum (Al) and sulfur (S) to form aluminum sulfide (Al2S3). It's also already balanced.

If you have any specific questions or need further information about these reactions, please feel free to ask!
