The answer is 4 (four).
Hope this helps!!! :)
The reaction that should be followed is
Na2SO4 + C<span>a(NO3)2 --> CaSO4 + 2NaNO3</span>
first calculate the limiting reactant
mol Na2SO4 = 0.075 L (<span>1.54×10−2 mol / L) = 1.155x10-3 mol
mol Ca(NO3)2 = 0.075 L (</span><span>1.22×10−2 mol / L) = 9.15x10-4 mol
so the limiting reactant is the Ca(NO3)2
so all of the Ca2+ will be precipitated, percentage unprecipitated = 0.00 % </span>

The answer to your question is:
Explanation:
See the attachment
An element that is composed of a multiple bond is one that is formed between 2 atoms, and the electrons are shared, therefore, resulting in a neutral charge.
