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:
Explanation:
By rearrangement of atoms of reactants. The entire properties will also different from the reactants as the composition changes.

Answer:
d
Explanation:
I believe the answer to this question is d , I believe this as the question doesn't explain properly the surface under the boulder. it is questionable as the question is not clear though I believe this as there must be friction under the boulder stopping it from moving.
