Elemental iodine (I 2) is a solid at room temperature. What is the major attractive force that exists among different I 2 molecu
1 answer:
Explanation:
As is a covalent compound because it is made up by the combination of two non-metal atoms. Atomic number of an iodine atom is 53 and it contains 7 valence electrons as it belongs to group 17 of the periodic table.
Therefore, sharing of electrons will take place when two iodine atoms chemically combine with each other leading to the formation of a covalent bonding.
Hence, weak forces like london dispersion forces will be present between a molecule of .
The weak intermolecular forces which can arise either between nucleus and electrons or between electron-electron are known as dispersion forces. These forces are also known as London dispersion forces and these are temporary in nature.
thus, we can conclude that london dispersion force is the major attractive force that exists among different molecules in the solid.

Answer: Three things are missing:
i) Graph title.
ii) Label for the vertical axis.
iii) The scale and the units for the horizontal axis.
Justification:
1) Find the graph in the image attached.
2) What does the graph represent? You cannot tell because it does not show the tittle.
Since you are told in the statement that it is a temperature and volume graph, the appropiate title would be:
Temperature vs. Volume.
3) The vertical axis also must be properly labeled, including the units.
A good label for the vertical axis of this graph might be: Volume (cm³). It migh also be liters, gallons, or other volume unit.
4) Although the horizontal axis is labeled, it does not indicate the units and the scale. So, you know neither if the temperature shown is celsius, (°C), farenheti (°F), kelvin (K), or rankine (R) (those are the four major scales of temperature), nor how much each division represent (1, 5, 10, 10, 50, 100?)
