it could be c or d. C is more correct
Explanation:
This question is very unclear. Does the water cool off? No?
If the water stays at 50 degrees C, then the volume increases. This is because rising temperature causes particles to separate and expand, moving faster.
Answer : The entropy change of the system is, 361.83 J/K
Solution :
Formula used :
where,
= entropy change of the system = ?
= enthalpy of vaporization = 34.6 kJ/mole
n = number of moles of diethyl ether = 4.20 mole
= normal boiling point =
Now put all the given values in the above formula, we get the entropy change of the system.
Therefore, the entropy change of the system is, 361.83 J/K
This the example of a colloids
Answer: 82.5979
cuz there are 6.941 in each mole of lithium
<span>Mendeleev's periodic table was in error because when the elements were arranged by mass it resulted in several elements being placed in groups of elements with differing properties.</span>
