Question

HCL=CuCl2=CuNo32=CuOH2

Answer 1

Ответ:

1. 2 HCl + Cu ← H2 + CuCl2
2. 2AgNO3 + CuCl2 = Cu(NO3)2 + 2AgCl
3. 2NaOH + Cu(NO3)2 =2 NaNO3 + Cu(OH)2

Answer 2

It seems like you've provided a list of chemical formulas, but there are some inaccuracies in your representation. Let's break down each of these:

1. HCl - This is hydrochloric acid, a strong acid formed by hydrogen (H) and chlorine (Cl) ions.

2. CuCl2 - This is copper(II) chloride, a chemical compound consisting of copper (Cu) in its +2 oxidation state and two chlorine (Cl) ions.

3. Cu(NO3)2 - This is copper(II) nitrate, a compound composed of copper (Cu) in its +2 oxidation state and two nitrate (NO3-) ions.

4. Cu(OH)2 - This is copper(II) hydroxide, a compound made up of copper (Cu) in its +2 oxidation state and two hydroxide (OH-) ions.

It seems like you might have confused the formulas or made some typographical errors. Each of these compounds has distinct chemical compositions and properties. If you have a specific question about any of these compounds or their relationships, please feel free to ask!
