The given reaction involves nickel(II) nitrate, \(\mathrm{Ni}\left(\mathrm{NO}_{3}\right)_{2}\), and sodium hydroxide, \(\mathrm{NaOH}\). When these react, they form nickel(II) hydroxide, \(\mathrm{Ni(OH)}_{2}\), and sodium nitrate, \(\mathrm{NaNO}_{3}\).
Step 2: Write the Balanced Chemical Equation
To balance the chemical equation, ensure that the number of atoms of each element is the same on both sides of the equation.
