Mi-это что? Написала несколько, выбирай нужную.

4Mg + 5H2SO4 → 4MgSO4 + H2S + 4H2O

3Mn + 4H2SO4 → 3MnSO4 + 4H2O + S

Mo + 4H2SO4 → Mo(SO4)2 + 2SO2 + 4H2O

8Na + 5H2SO4 → 4Na2SO4 + H2S + 4H2O

4Ca + 5H2SO4 → 4CaSO4 + H2S + 4H2O

Answer 2

It seems like you want to know the reactions of sulfuric acid (H2SO4) with different metals, specifically with magnesium (Mg), sodium (Na), and calcium (Ca). Sulfuric acid is a strong acid, and its reactions with metals typically involve the displacement of hydrogen gas (H2) and the formation of metal sulfate salts. Here are the reactions:

1. Sulfuric Acid (H2SO4) + Magnesium (Mg): H2SO4 + Mg → MgSO4 + H2

   In this reaction, magnesium (Mg) reacts with sulfuric acid to form magnesium sulfate (MgSO4) and hydrogen gas (H2) is released.

2. Sulfuric Acid (H2SO4) + Sodium (Na): H2SO4 + 2Na → Na2SO4 + 2H2

   Sodium (Na) reacts with sulfuric acid to produce sodium sulfate (Na2SO4) and hydrogen gas (H2) is released.

3. Sulfuric Acid (H2SO4) + Calcium (Ca): H2SO4 + Ca → CaSO4 + H2

   Calcium (Ca) reacts with sulfuric acid to form calcium sulfate (CaSO4) and hydrogen gas (H2) is released.

In all these reactions, hydrogen gas is produced as a byproduct, and the metal sulfate salt is formed. These reactions are examples of metal-acid reactions, and they release hydrogen gas due to the displacement of hydrogen ions (H+) by the metal ions. Please note that these reactions are simplified and may not represent the actual laboratory conditions or stoichiometry in a specific experiment. Safety precautions should be taken when working with strong acids like sulfuric acid.
