Question

Pt+HNO3=?????????????????​

Answer 1

Ответ:

Pt + 4HNO3 → Pt(NO3)2 + 2NO2 + 2H2O

Answer 2

Pt + 4HNO3 → Pt(NO3)2 + 2NO2 + 2H2O

Answer 3

The reaction between Pt (platinum) and HNO3 (nitric acid) produces platinum nitrate (Pt(NO3)4) and other nitrogen oxides as products. The balanced chemical equation for this reaction is as follows:

Pt + 4 HNO3 → Pt(NO3)4 + 4 H2O + NOx

Please note that "NOx" represents various nitrogen oxides that can be formed during the reaction, such as nitrogen monoxide (NO) and nitrogen dioxide (NO2), depending on the specific conditions.
