Question

Помогите ,пожайлуста.(химия,8класс) N2O3+ZnO=? Li2O+BeO=? SrO+Cr2O3=?

Answer 1

N2O3 + ZnO = Zn(NO2)
Li2O + BeO = Li2BeO3
SrO + Cr2O3 = Sr(CrO2)2

Answer 2

N2O3 + ZnO

When N2O3 reacts with ZnO, they form a compound. The balanced chemical equation for this reaction is:

2 N2O3 + 3 ZnO → 3 Zn(NO3)2

So, when N2O3 reacts with ZnO, it forms zinc nitrate (Zn(NO3)2).

Li2O + BeO

When Li2O reacts with BeO, they form a compound. The balanced chemical equation for this reaction is:

Li2O + BeO → LiBeO2

So, when Li2O reacts with BeO, it forms lithium beryllate (LiBeO2).

SrO + Cr2O3

When SrO reacts with Cr2O3, they form a compound. The balanced chemical equation for this reaction is:

3 SrO + 2 Cr2O3 → 3 SrCrO4

So, when SrO reacts with Cr2O3, it forms strontium chromate (SrCrO4).

I hope this helps! Let me know if you have any further questions.
