<span>According to Mendeleyev-Klapeyron’s equation
pV = nRT,
where p = 160 atm V = 12 R -constant 0.0821 & T = 298 in Kelvin
Using given data, we can determine the amount of Helium gas:
n = pV/RT = (160â™12)/(0,0821â™298) = 78,48 (mol)
For atmospheric pressure (1 atm) and the same amount we can calculate the volume of tank, using previous equation:
V = nRT/p = (78,48â™0,0821â™298)/1 = 1920 (liters)
V = 1920 liters
Thus Answer is 1920 liters</span>
Answer:
The correct answer is The overall enthalpy of the system increases during the change.
Explanation:
Exothermic is type of chemical reaction that deals with the generation of energy in form of heat.Exothermic reactions are thermodynamically favorable because free energy change during exothermic reaction is highly negative.
Enthalpy is a state function which measures the heat content of the system.As there is a generation of heat from the reaction to the system in which the reaction is taking place,the heat content of the system increases which ultimately result in increasing the overall change of the enthalpy.
1000 mg = 1 gram
4182 mg = x [grams]
1000 / 4182= 1/x Cross multiply
1000x = 4182 * 1
1000x = 4182 Divide by 1000
x = 4182 / 1000
x = 4.182 grams. <<<<< answer.
The answer was D or Hydraulic action.
