Answer:
D. Grams liquid x mol/g x delta Hfreezing
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to reason that the stoichiometry used to calculate energy released when a mass of liquid freezes, involves the grams of the liquid, the molar mass of the liquid, as given in all the group choices, and the enthalpy of freezing because that is the process whereby a liquid goes solid.
In such a way, we infer that the correct factor would be D. Grams liquid x mol/g x delta Hfreezing which sometimes is the negative of the enthalpy of fusion as they are contrary processes.
Regards!
Answer:
copper
Explanation:
The density of copper is 8.96 g/cm³ and the density of zinc is 7.13 g/cm³.
density= mass/volume
⇒mass = density×volume
For copper,
mass = 8.96 g/cm³ × 1 cm³
mass = 8.96 grams
For zinc,
mass = 7.13 g/cm³ × 1 cm³
mass = 7.13 grams
It is clear that, the mass of copper is more.
