Question

5.10. Напишите уравнение реакции кислотного оксида с во- дой, если такая реакция идет. а) MnO2 + H20 - б) N2O3 + H20 - в) SO3 + H20 — г) SiO2 + H20 — д) CO2 + H20 - e) B2O3 + H20 — 5 11 но

Answer 1

Так,реакция протекает,если образуется осадок,газ,или слабый электролит(например вода)

а)MnO2+H2O не протекает

б)N2O3+H2O = 2HNO2

в)SO3+H2O = H2SO4

г)SiO2+H2O = H2SiO3

д)CO2+H2O = H2CO3

е)B2O3+3H2O =2H3BO3

удачи ))

Answer 2

Equation for the Reaction of Acidic Oxides with Water

When acidic oxides react with water, they typically form oxyacids. The general equation for the reaction of an acidic oxide (represented as MOx) with water (H2O) can be written as:

MOx + H2O → H2MOx

In this equation, MOx represents the acidic oxide and H2MOx represents the resulting oxyacid.

Now, let's write the equations for the specific reactions mentioned:

a) MnO2 + H2O → H2MnO3 b) N2O3 + H2O → 2HNO2 c) SO3 + H2O → H2SO4 d) SiO2 + H2O → H2SiO3 e) CO2 + H2O → H2CO3 f) B2O3 + H2O → 2H3BO3

Please note that these equations represent the general reaction pattern for acidic oxides reacting with water. The specific products may vary depending on the nature of the oxide and the reaction conditions.
