Question

CuCl2 = Cu(OH)2 = CuSO4 = Cu

Answer 1

1.CuCl2 + 2NaOH =Cu(OH)2 + 2NaCl
2.Cu(OH)2 + H2SO4 = CuSO4 + 2H2O
3.CuSO4 + Fe= Cu + FeSO4

Answer 2

It appears that you are equating different chemical compounds involving copper (Cu) and various anions (Cl, OH, SO4). However, these compounds are not equal; they have distinct chemical formulas and properties. Let's break them down:

1. CuCl2: This is copper(II) chloride, which consists of copper ions (Cu^2+) and chloride ions (Cl^-).

2. Cu(OH)2: This is copper(II) hydroxide, composed of copper ions (Cu^2+) and hydroxide ions (OH^-).

3. CuSO4: This is copper(II) sulfate, comprising copper ions (Cu^2+) and sulfate ions (SO4^2-).

4. Cu: This represents elemental copper, where copper atoms exist in their metallic form.

These compounds are chemically distinct and have different properties. It's essential to recognize that they are not interchangeable or equal in any chemical reaction or context. They have specific uses and applications in chemistry and various industries.
