Question

Закончить реакции которые происходят расставить коефициентыZn+H2SO4=Al+HCl=Pb+H3PO4=Au+HI=

Answer 1

Zn+H2SO4=ZnSO4+H2
2Al+6HCl=2AlCl3+3H2
3Pb+2H3PO4=Pb3(PO4)2+3H2
Au+HI=реакция не идёт

Answer 2

Reaction 1: Zn + H2SO4

The reaction between zinc (Zn) and sulfuric acid (H2SO4) produces zinc sulfate (ZnSO4) and hydrogen gas (H2).

The balanced chemical equation for this reaction is:

Zn + H2SO4 → ZnSO4 + H2

Reaction 2: Al + HCl

The reaction between aluminum (Al) and hydrochloric acid (HCl) produces aluminum chloride (AlCl3) and hydrogen gas (H2).

The balanced chemical equation for this reaction is:

2Al + 6HCl → 2AlCl3 + 3H2

Reaction 3: Pb + H3PO4

The reaction between lead (Pb) and phosphoric acid (H3PO4) produces lead(II) phosphate (Pb3(PO4)2) and hydrogen gas (H2).

The balanced chemical equation for this reaction is:

3Pb + 2H3PO4 → Pb3(PO4)2 + 3H2

Reaction 4: Au + HI

The reaction between gold (Au) and hydroiodic acid (HI) does not produce a simple binary compound. Gold does not readily react with hydroiodic acid under normal conditions.

Please note that the reactions mentioned above are simplified representations of the chemical reactions. In reality, there may be additional factors and conditions that can affect the reactions.
