Question

Hno3+naoh=? Ba(oh) 2+n2o5=?Hno3+k2co3=?Hno3+cuo=? ​

Answer 1

Ответ:

HNO3 + NaOH → NaNO3 + H2O

Ba(OH)2 + N2O5 → Ba(NO3)2 + H2O

K2CO3 + 2HNO3 → 2KNO3 + H2O + CO2

CuO + 2HNO3 → Cu(NO3)2 + H2O

Answer 2

Here are the balanced chemical equations for the reactions you've mentioned:

1. HNO3 + NaOH: This is a neutralization reaction, and it produces water (H2O) and sodium nitrate (NaNO3) as products. The balanced equation is:

   HNO3 + NaOH → NaNO3 + H2O

2. Ba(OH)2 + N2O5: This is a double displacement reaction, and it forms barium nitrate (Ba(NO3)2) and dinitrogen pentoxide (N2O5) as products. The balanced equation is:

   Ba(OH)2 + N2O5 → Ba(NO3)2 + H2O2

3. HNO3 + K2CO3: This is a double displacement reaction, and it generates potassium nitrate (KNO3), carbon dioxide (CO2), and water (H2O) as products. The balanced equation is:

   2 HNO3 + K2CO3 → 2 KNO3 + CO2 + H2O

4. HNO3 + CuO: This is a redox reaction, where copper(II) oxide (CuO) is reduced to copper(II) nitrate (Cu(NO3)2), and nitric acid (HNO3) is oxidized. The balanced equation is:

   4 HNO3 + CuO → Cu(NO3)2 + 2 H2O + 2 NO2

Please note that the balancing coefficients in these equations are derived from the principle of conservation of mass and charge.
