The solutions vapor pressure would be lower.
Answer:
(d) Na₂CO₃ + CuSO₄ → Na₂SO₄ + CuCO₃
Explanation:
Chemical reaction:
Na₂CO₃ + CuSO₄ → Na₂SO₄ + CuCO₃
This is metathesis reaction. It is also called double displacement reaction. The cation and anions of both reactants exchange with each others.
The cation (Na⁺) of sodium carbonate is exchange with cation (Cu²⁺) of copper sulfate and form sodium sulfate and copper carbonate.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC + BD

Molar gas=given volume ÷ molar volume
x=0.5÷22.4=0.02
now=0.02×2.5=0.05
mass =0.05
