# of protons + # of neutrons = mass
9 + 10 = 19
the answer is D
Answer:
The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster.
Explanation:
This added movement tends to make the bonds between sucrose molecules easier to overcome.
Hope it helps :-)
Answer:
The detailed calculation is shown in the attached file.
last condition (1000 K in 150.000 dm3) will have the least deviations and it is the condition where real gas will behave as ideal gases
Explanation:
Real gas behave more ideally or they tend towards ideality when there is the least deviation, or their inter-molecular forces between their molecules are mainly responsible for their deviations as such gases with the strongest intermolecular forces shows the strongest deviations. As such, when their is an increase in temperature and volume and a decrease in pressure, real gas tends towards ideal gas in this case.
From the three conditions given, it is obvious that the last condition(1000 K in 150.000 dm3) will have the least deviations.
Hello!
We have the following data:
v (volume) = ? (in L)
n (number of mols) = 1,5 mol
T (temperature) = 22 ºC
First let's convert the temperature on the Kelvin scale, let's see:
TK = TºC + 273,15
TK = 22 + 273,15
TK = 295,15
P (pressure) = 100 kPa → P = 100000 Pa → P ≈ 0,987 atm
R (gas constant) = 0,082 atm.L / mol.K
<span>We apply the data above to the Clapeyron equation (gas equation), let's see:

I hope this helps. =)
