Question

Mr(Cu(OH)2) = Help me

Answer 1

Мr = 64+16*2+1*2=98 вроде бы так.

Answer 2

Chemical Formula for Copper(II) Hydroxide

The chemical formula for copper(II) hydroxide is Cu(OH)2.

Properties of Copper(II) Hydroxide

Copper(II) hydroxide is a blue solid that is sparingly soluble in water. It is commonly used as a fungicide and an agricultural bactericide.

Chemical Reactions Involving Copper(II) Hydroxide

Copper(II) hydroxide can participate in various chemical reactions. For example, when reacted with hydrochloric acid (HCl), it forms copper(II) chloride (CuCl2) and water (H2O). The balanced chemical equation for this reaction is:

``` Cu(OH)2 + 2HCl → CuCl2 + 2H2O ``` This reaction is a double displacement reaction, where the positive ions in the reactants switch places.

Conclusion

Copper(II) hydroxide, with the chemical formula Cu(OH)2, is a blue solid with limited solubility in water. It is commonly used in agricultural applications as a fungicide and bactericide. When reacted with hydrochloric acid, it forms copper(II) chloride and water.
