Copper (II) Carbonate + Heat yields copper (II) oxide and carbon dioxide
Molecular Equation: CuCo3 + heat > CuO + CO2
Answer:
E
Explanation:
no of grams in picture c = A+B
= 200+10 =210
for D its also 210 ..... the water already contains the salt .....so the mass of salt has added to the mass of water which is still 210
