Answer : The temperature of the chloroform will be, 
Explanation :
First we have to calculate the mass of chloroform.

conversion used : 
Now we have to calculate the temperature of the chloroform.
Formula used :

where,
q = amount of heat or energy = 1.46 kJ = 1460 J (1 kJ = 1000 J)
= specific heat capacity = 
m = mass of substance = 110.958 g
= final temperature = ?
= initial temperature = 
Now put all the given values in the above formula, we get:


Now we have to convert the temperature from Kelvin to Fahrenheit.
The conversion used for the temperature from Kelvin to Fahrenheit is:

As we know that,
or, 

...........(1)
Now put the value of temperature of Kelvin in (1), we get:


Therefore, the temperature of the chloroform will be, 
Answer:
A) H₂O at 120°C
Explanation:
It is possible to think the higher temperature, the greatest degree of disorder. That is because with a high temperature, vibrations of molecules increases.
In general, at low temperatures, the molecules are in solid state (The lowest degree of disorder), increasing its temperature, molecules becomes in liquids, and, with more temperature, are gases (The greatest degree of disorder).
Thus, the sample that has the greatest degree of disorder is:
<h3>A) H₂O at 120°C</h3>
Answer:
The charge is +2
Explanation:
Protons are positive, electrons are negative. 10-8=2.
+2 :)
Answer:
Explanation:
(a) Answer: Intermolecular forces
The reason for this answer is because the substance (paraffin wax) only changed it's state from solid to liquid and didn't undergo a breakage in it's covalent bond within it's carbon chain which would have produced another substance.
(b) Solid substances are generally more dense than there corresponding liquid substances because the more compact particles are (which occurs in solids), the more dense they become. They are thus more dense than liquids because liquids have there particles loosely packed and well spaced making them less dense than there corresponding solids. Hence, the solid paraffin wax was going to become less dense because it's particles moved from being tightly packed (as solids) to being loosely packed (as liquids). Density refers to mass per volume but can also be described as the level of compactness of a substance. Thus, since liquid is not as compact as solid, it can be said to be less dense than solids.
