Question

1) H2SO4 (концентрированная) + S = H2O + SO2 2) H2S + I2 = HI + S 3) H2SO4 (концентрированная) + P =H3PO4 + SO2 4) H2SO4 (концентрированная) + Ag = Ag2SO4 + SO2 + H2O 5) H2SO4 (концентрированная) + Zn = ZnSO4 + H2O + S

Answer 1

2H2SO4(конц.) + 2Ag = Ag2SO4 + SO2 + 2H2O
H2S + I2 = S  + 2HI
5H2SO4 + 2P=2H3PO4+5SO2+2H2О
5H2SO4(конц.) + 4Zn = 4ZnSO4 + H2S↑ + 4H2O
2H2SO4(конц.) + S = 3SO2 + 2H2O

Answer 2

Chemical Reactions:

1) H2SO4 (concentrated) + S = H2O + SO2 - This reaction involves the reaction between concentrated sulfuric acid (H2SO4) and sulfur (S). - The products of this reaction are water (H2O) and sulfur dioxide (SO2).

2) H2S + I2 = HI + S - This reaction involves the reaction between hydrogen sulfide (H2S) and iodine (I2). - The products of this reaction are hydrogen iodide (HI) and sulfur (S).

3) H2SO4 (concentrated) + P = H3PO4 + SO2 - This reaction involves the reaction between concentrated sulfuric acid (H2SO4) and phosphorus (P). - The products of this reaction are phosphoric acid (H3PO4) and sulfur dioxide (SO2).

4) H2SO4 (concentrated) + Ag = Ag2SO4 + SO2 + H2O - This reaction involves the reaction between concentrated sulfuric acid (H2SO4) and silver (Ag). - The products of this reaction are silver sulfate (Ag2SO4), sulfur dioxide (SO2), and water (H2O).

5) H2SO4 (concentrated) + Zn = ZnSO4 + H2O + S - This reaction involves the reaction between concentrated sulfuric acid (H2SO4) and zinc (Zn). - The products of this reaction are zinc sulfate (ZnSO4), water (H2O), and sulfur (S).
