Answer 2

The equation you provided is not balanced. Let's balance the chemical equation for the reaction between CrO2 and HCl.

The balanced chemical equation for the reaction between CrO2 (chromium(IV) oxide) and HCl (hydrochloric acid) is:

CrO2 + 4HCl (конц) → CrCl2 + 2H2O

Balancing the equation:

1 CrO2 + 4 HCl → 1 CrCl2 + 2 H2O

This balanced equation shows that one molecule of CrO2 reacts with four molecules of concentrated hydrochloric acid (конц) to produce one molecule of chromium(II) chloride (CrCl2) and two molecules of water (H2O).
