Question

copper(ii) hydroxide decomposes into copper(ii) oxide and water when heated. which reaction shows the correct reactants and products? cu(oh)₂→cuo + h₂o cu(oh)₂→cuo₂ + h₂o cu(oh)→cu₂o + h₂o cu₂oh→cu₂o + h₂o

Explanation:

Step1: Analyze the formula of copper(II) hydroxide

Copper(II) hydroxide has the formula \(Cu(OH)_2\).

Step2: Analyze the formula of copper(II) oxide

Copper(II) oxide has the formula \(CuO\).

Step3: Check the reaction

The reaction \(Cu(OH)_2
ightarrow CuO + H_2O\) has the correct reactant (\(Cu(OH)_2\)) and products (\(CuO\) and \(H_2O\)).

Answer:

\(Cu(OH)_2
ightarrow CuO + H_2O\)
