Answer 1

Ответ:

1) Ba + 2AgNO₃ → Ba(NO₃)₂ + 2Ag

2) Cu(NO₃)₂+ 2Na → 2NaNO₃ + Cu

3) Pb(NO₃)₂+ 2K → 2KNO₃ + Pb

4) Mg + K2SO4 → MgSO4 + 2K

5) 5Zn + 12HNO3 → 5Zn(NO3)2 + 6H2O + N2

6)Ca(NO₃)₂+ H₂ →  CaH2 + 2NO3

7) Ba + Na₂SO₄ → 2Na + BaSO₄

Answer 2

1) Ba + AgNO3 → Ba(NO3)2 + Ag - The reaction between barium (Ba) and silver nitrate (AgNO3) produces barium nitrate (Ba(NO3)2) and silver (Ag) [[1]].

2) Cu(NO3)2 + 2Na → Cu + 2NaNO3 - The reaction between copper(II) nitrate (Cu(NO3)2) and sodium (Na) produces copper (Cu) and sodium nitrate (NaNO3) [[2]].

3) Pb(NO3)2 + 2K → Pb + 2KNO3 - The reaction between lead(II) nitrate (Pb(NO3)2) and potassium (K) produces lead (Pb) and potassium nitrate (KNO3) [[3]].

4) Mg + K2SO4 → MgSO4 + 2K - The reaction between magnesium (Mg) and potassium sulfate (K2SO4) produces magnesium sulfate (MgSO4) and potassium (K) [[4]].

5) HNO3 + Zn → Zn(NO3)2 + H2 - The reaction between nitric acid (HNO3) and zinc (Zn) produces zinc nitrate (Zn(NO3)2) and hydrogen gas (H2) [[5]].

6) Ca(NO3)2 + H2 → Ca + 2HNO3 - The reaction between calcium nitrate (Ca(NO3)2) and hydrogen gas (H2) produces calcium (Ca) and nitric acid (HNO3) [[6]].

7) Ba + Na2SO4 → BaSO4 + 2Na - The reaction between barium (Ba) and sodium sulfate (Na2SO4) produces barium sulfate (BaSO4) and sodium (Na) [[7]].

Please note that these reactions are simplified and may not represent the complete reaction mechanisms or conditions required for the reactions to occur.
