Answer:
The air in the room
Explanation:
The diffrent temp of the water compared to the room. The water was colder than the room.
Sulfur is a group six element in period 3 with atomic number 16 and an electronic configuration of 2:8:6. Therefore, to attain a stable configuration it requires to gain two electrons forming an ion with a charge of -2. The negative charge is due to the gaining of electrons.
This site is used for learning, so to give a better understanding, here is a walkthrough.
So let's create a question:
Can a molecule have a dipole moment if it has no polar covalent bonds?
Here's the answer to that question:
Even though a molecule contains only one element, it can have a persistent dipole moment. The most common example is ozone (trioxygen). It is curved and has a partial positive charge on the center oxygen atom (similar to sulfur dichloride).
Permanent dipole moments are caused by an unequal, directed charge distribution within a molecule, not by changes in electronegativity. Such charge distributions are frequently caused by so-called "polar covalent bonds," which occur between atoms with markedly varying electronegativity. However, they are not the sole explanation.
So using this information, try to answer this question on your own.

Answer:
The correct answer is - B) gaining electrons will fill their octet faster than losing them.
Explanation:
Halogens are located in the 17 th group in the periodic table and have elements like fluorine, chlorine bromine and others. All these elements are nonmetals and have similar electron numbers in their octet.
That is the reason of their high effective nuclear charge as they are electronegative and therefore readily get electrons to become anion with other elemnts in chemical reaction. These elements make anion formed when a nonmetal atom gains one or more electrons.
Answer:
A2X<span>, δHvap= 39.6 kj/mol is the correct answer.
Explanation:
Heat of Vaporization is defined as the minimum amount of energy required to convert a liquid substance into a gas.
In liquids the intermolecular forces are stronger as compared to gases. In order to break these intermolecular forces a heat is supplied. Now, depending upon the nature of these interactions the amount of heat required varies.
Stronger the intermolecular forces greater will be the energy required to break them. Hence in above statement the greatest energy is associated with compound A2X (39.6 kJ/mol) as compared to others, therefore it will be having strongest intermolecular forces as compared to other given compounds.</span>
