Question

помогите, пожалуйста решить Cu2++ 20H-=Cu(OH)2

Answer 1

В скобках указаны заряды ионов 

Cu(+2) + 2OH(-) = Cu(OH)2 (осадок) - сокращенное ионное 

Сu(+2) + 2Cl(-) + 2Na(+) + 2OH(-) = 2Na(+) + 2Cl(-) + Cu(OH)2 (осадок) - полное ионное 

СuCl2 + 2NaOH = 2NaCl + Cu(OH)2 (осадок) - молекулярное

Answer 2

Balancing the Equation: Cu2+ + 2OH- = Cu(OH)2

To balance the chemical equation Cu2+ + 2OH- = Cu(OH)2, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The equation represents the reaction between copper(II) ions (Cu2+) and hydroxide ions (OH-) to form copper(II) hydroxide (Cu(OH)2).

Let's balance the equation step by step:

1. Start by counting the number of atoms of each element on both sides of the equation: - On the left side: 1 Cu and 2 O - On the right side: 1 Cu, 2 O, and 2 H

2. Balance the copper (Cu) atoms: - Since there is 1 Cu atom on both sides, the copper atoms are already balanced.

3. Balance the oxygen (O) atoms: - On the left side, there are 2 O atoms from the hydroxide ions. - On the right side, there are 2 O atoms from the copper(II) hydroxide. - The oxygen atoms are already balanced.

4. Balance the hydrogen (H) atoms: - On the right side, there are 2 H atoms from the hydroxide ions in the copper(II) hydroxide. - To balance the hydrogen atoms, we need to add 2 H+ ions on the left side of the equation.

The balanced equation is: Cu2+ + 2OH- = Cu(OH)2 + 2H+

Please note that the equation is now balanced in terms of atoms. However, if you are looking to balance the charges as well, you would need to consider the overall charge on both sides of the equation. In this case, the charges are already balanced, as the Cu2+ ion on the left side has a charge of +2, and the Cu(OH)2 compound on the right side also has a charge of +2.

I hope this helps! Let me know if you have any further questions.
