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>
Answer:
2
Explanation:
because hydrogen is a diatomic element, so it can't be just H
The answer should be "Dunes"
Answer: The actual value of 
is -618 J/mol
Explanation:
Relation of ree energy change and equilibrium constant
where,
= Free energy change
= standard free energy change = +29 kJ/mol =
R = universal gas constant
T = temperature = 
= equilibrium constant = 
The actual value of is -618 J/mol
