Answer:
4.17L
Explanation:
V1 = 10L
V2 =?
P1 = 500torr
P2 = 1200torr
Boyle's law states that at constant temperature, the volume of a gas is inversely proportional to its pressure.
P1V1 = P2V2
V2 = ( P1 * V1 ) / P2
V2 = 4.17L
The new volume of the gas is 4.17L

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!
I don’t understand. Is there a picture? Where are the options?
