Answer 1

Соответствие: реагирующие вещества и продукты взаимодействия:

1)  а)
                                   t     
1)  H₂SO₄+2NaCl(тв) = 2HCl↑+Na₂SO₄

2) г)
2)  5H₂SO₄(конц. ) + 4Zn = 4ZnSO₄ + H₂S↑ + 4H₂O

3) е)
3) H₂SO₄(разб)+Zn = ZnSO₄+H₂↑

4) д)
4) H₂SO₄+ZnO = ZnSO₄+H₂O

Answer 2

Matching Reactants with Products

1) H2SO4 + NaCl (тв) - Product: HCl + Na2SO4 - This reaction results in the formation of hydrochloric acid (HCl) and sodium sulfate (Na2SO4) [[1]].

2) H2SO4 + Zn - Product: ZnSO4 + H2 - The reaction between sulfuric acid (H2SO4) and zinc (Zn) produces zinc sulfate (ZnSO4) and hydrogen gas (H2) [[2]].

3) H2SO4(разб) + Zn - Product: ZnSO4 + H2 - When concentrated sulfuric acid (H2SO4) is used in the reaction with zinc (Zn), it also produces zinc sulfate (ZnSO4) and hydrogen gas (H2) [[3]].

4) H2SO4 + ZnO - Product: ZnSO4 + H2O - The reaction between sulfuric acid (H2SO4) and zinc oxide (ZnO) yields zinc sulfate (ZnSO4) and water (H2O) [[4]].

Conclusion

The given reactions and their corresponding products have been matched based on the provided information. If you have any further questions or need additional assistance, feel free to ask!
