Question

Необходимо записать в ионном виде Cu(NO3)2+NaOH→Cu(OH)2↓+2NaNo3 CuSO4+BaCl2→CuCl2+BaSO4↓ Zn(No3)2+Mg→Mg(NO3)2+Zn

Answer 1

Ответ:

2NaOH+ Cu(NO3)2 → Cu(OH)2+ 2NaNO3

2Na(+) + 2OH(-) + Cu(2+) + 2NO3(-) → Cu(OH)2 + 2Na(+) + 2NO3(-)

Cu(2+) + 2OH(-) → Cu(OH)2 - ионное сокращенное уравнение.

CuSO4+BaCl2→CuCl2+BaSO4↓

Сu(2+) +SO4(2-) +2Cl(-) + Ba(2+) → BaSO4 + Cu(2+) + 2Cl(-)

SO4(2-)+Ba(2+) → BaSO4

2Mg + Zn(NO3)2 → 2Mg(NO3) + Zn

здесь нет нерастворимых веществ, поэтому не решается

Ionic Equations

The ionic equations for the given chemical reactions are as follows:

1. Cu(NO3)2 + 2NaOH → Cu(OH)2↓ + 2NaNO3 The ionic equation for this reaction is: ``` Cu^2+ + 2NO3^- + 2Na^+ + 2OH^- → Cu(OH)2↓ + 2Na^+ + 2NO3^- ```

2. CuSO4 + BaCl2 → CuCl2 + BaSO4↓

The ionic equation for this reaction is: ``` Cu^2+ + SO4^2- + Ba^2+ + 2Cl^- → Cu^2+ + 2Cl^- + BaSO4↓ ```

3. Zn(NO3)2 + Mg → Mg(NO3)2 + Zn

The ionic equation for this reaction is: ``` Zn^2+ + 2NO3^- + Mg → Mg^2+ + 2NO3^- + Zn ```

These ionic equations represent the dissociation of the compounds into their respective ions and the subsequent recombination to form the products.
