Question

III вapiaнT: FeCl3 + KI= FeCl₂ + 1₂ + KCI Zn + H₂SO4= ZnSO4+H₂1 NH3 + O₂ → NO₂ + H₂O T​

Answer 1

FeCl3 + 3KI → FeCl2 + I2 + 3KCl

Zn + H2SO4 → ZnSO4 + H2

4NH3 + 5O2 → 4NO2 + 6H2O

Answer 2

It seems like you've provided some chemical reactions, but there are some issues with the chemical equations you've written. Let me correct them for you:

1. FeCl3 + KI → FeCl2 + I2 + KCl (This equation is balanced)

   This reaction involves the reaction between iron(III) chloride and potassium iodide to form iron(II) chloride, iodine, and potassium chloride.

2. Zn + H2SO4 → ZnSO4 + H2 (This equation is balanced)

   This reaction is a classic example of a metal (zinc) reacting with an acid (sulfuric acid) to produce a salt (zinc sulfate) and hydrogen gas.

3. NH3 + O2 → NO2 + H2O (This equation is balanced)

   This equation represents the combustion of ammonia in the presence of oxygen to form nitrogen dioxide and water.
