Zn-zns-h2s-na2s-na2so4​

Answer 1

Ответ: zn-zns-h2s-na2s-na2so4​

1)Zn+S=ZnS

2)ZnS+2HCI=ZnCI2+H2S

3)H2S+NaOH=Na2S+H2O

4)Na2S+H2SO4=Na2SO4+H2S

Answer 2

The given sequence "Zn-ZnS-H2S-Na2S-Na2SO4" represents a series of chemical reactions involving zinc (Zn) and various sulfur compounds. Let's break down the reactions step by step:

1. Zn (Zinc) reacts with sulfur (S) to form ZnS (Zinc sulfide): Zn + S → ZnS

2. ZnS reacts with hydrogen sulfide (H2S) to form hydrogen gas (H2) and Na2S (Sodium sulfide): ZnS + H2S → H2 + Na2S

3. Na2S (Sodium sulfide) reacts with H2S to form Na2S2 (Disodium disulfide): Na2S + H2S → Na2S2

4. Na2S2 reacts with oxygen (O2) to form Na2SO4 (Sodium sulfate): Na2S2 + O2 → Na2SO4

Please note that the given sequence is a simplified representation of the reactions, and the actual reactions might involve additional reactants, products, or conditions. Additionally, specific reaction conditions such as temperature, pressure, and catalysts may also affect the outcome of the reactions.
