A: Not correct. One reactant is dissolved in water. The other is a solid that combines with the one reactant that is in water. That's what aqueous (aq) means.
B: CuCl2 is aqueous (the equation says so) ClCl2(aq) means that the copper chloride is in water. Whatever else B says, this much is true so that Statement B is false.
C: False. The reactants contain a liquid and a solid.
D: True. The statement is true because CuCO3 is labels as a solid(s), and CO2 is labeled as a gas (g).
E: is false. Where is the solid in the products?
Right Panel
Sample Mass: 33.5 grams
Volume: 3.2 cm^3
Density = mass / volume
Density = 33.5 / 3.2 = 10.47.
It can only be silver.
