Question

решите как можно быстреее
1 Li2O + H2O =
2 CaO+ HNO3 =
3 MgO +CO2 =
4 Al2O3 + HCl =
5 CuCO3 =
6 Cr(OH)3=
7 Fe2O3 + С =

Answer 1

Li₂O + H₂O → 2LiOH

CaO + 2HNO₃ → H₂O + Ca(NO₃)₂

MgO + CO₂ → MgCO₃

Al₂O₃ + 6HCl → 3H₂O + 2AlCl₃

CuCO₃ → CuO + CO₂

2Cr(OH)₃ → Cr₂O₃ + 3H₂O

Fe₂O₃ + 3C → 2Fe + 3CO
