Question

28 what is the chemical formula for copper(ll) nitrate? notebook b / u enter note here

Explanation:

Step1: Determine the ion of copper

Copper(II) has a charge of \(Cu^{2+}\).

Step2: Determine the nitrate ion

Nitrate ion is \(NO_3^-\).

Step3: Balance the charges

To balance the \(+2\) charge of \(Cu^{2+}\) with the \(-1\) charge of \(NO_3^-\), we need 2 \(NO_3^-\) ions.

Answer:

\(Cu(NO_3)_2\)
