Question

HNO3+Cr2O3=?HNO3+MnO=?

Answer 1

6HNO3+Cr2O3=2Cr(NO3)3+3Н2О
2HNO3+MnO=Mn(NO3)2+ Н2О

Answer 2

HNO3 + Cr2O3

The reaction between HNO3 (nitric acid) and Cr2O3 (chromium(III) oxide) can be represented as follows:

HNO3 + Cr2O3 → H2O + Cr(NO3)3

In this reaction, nitric acid reacts with chromium(III) oxide to produce water and chromium(III) nitrate.

HNO3 + MnO

The reaction between HNO3 (nitric acid) and MnO (manganese(II) oxide) can be represented as follows:

**HNO3 + MnO → H
