Elemental iodine (I 2) is a solid at room temperature. What is the major attractive force that exists among different I 2 molecu
Ulleksa [173]

Explanation:

As I_{2} 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 I_{2}.

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 I_{2} molecules in the solid.

What is the empirical formula of a substance that contains 2.64 g of c, 0.444 g of h, and 7.04 g of o?
vitfil [10]

To calculate empirical formula, number of moles of different atoms calculated first:

Number of moles of Carbon , n=  

=\frac{Given mass of carbon}{Molar mass of carbon}

=\frac{2.64 g}{12.011 g mol^{-1}}

= 0.220 mol  

Number of moles H =\frac{Given mass of hydrogen}{Molar mass of hydrogen}

=\frac{0.444 g}{1.008 g mol^{-1}}

= 0.440 mol

Number of moles of oxygen =\frac{Given mass of oxygen}{Molar mass of oxygen}

=\frac{7.04 g}{15.999 g mol^{-1}}

= 0.440 mol

Ratio of carbon

=\frac{0.220}{0.220}

= 1

Ratio of hydrogen

=\frac{0.440}{0.220}

= 2  

Ratio of oxygen

=\frac{0.440}{0.220}

= 2  

So, the empirical formula is CH₂O₂
