You would be correct, boiling water does disinfect contamination. the property of disinfecting means to kill germs, bacteria and other pathogens or contamination that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate. the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
0.98mole
Explanation:
Data obtained from the question include:
V (volume) = 25L
T (temperature) = 5.0°C = 5 + 273 = 278K
P (pressure) = 89.9 kPa
Recall: 1kPa = 1000Pa
89.9 kPa = 89.9 x 1000 = 89900Pa
But: 101325Pa = 1atm
Therefore, 89900Pa = 89900/101325 = 0.89atm
R (gas constant) = 0.082atm.L/Kmol
n (number of mole) =?
Using the ideal gas equation PV = nRT, we can obtain the number of mole of Neon gas as shown below:
PV = nRT
n = PV /RT
n = (0.89x25)/(0.082x278)
n = 0.98mole
Therefore, the number of mole of Neon gas present is 0.98mole
