Ethane (CH$_3$CH$_3$) exhibits London Dispersion Forces as its primary intermolecular force due to temporary dipoles in this non-polar molecule.

The balanced equation for the complete combustion of heptane $\text{C}_7\text{H}_{16}$ is:

During combustion, the rapid oxidation of a substance is accompanied by the release of energy in the form of heat and light along with the formation of gases such as $\text{CO}_2$ and $\text{H}_2\text{O}$.

The chemical formula for Lead (IV) chromate is $\text{Pb}(\text{CrO}_4)_2$.

The correct formula for Iron (III) Nitride, where iron has a $+3$ charge and nitride has a $-3$ charge, is $\text{FeN}$.

Electricity and magnetism are interrelated phenomena unified as electromagnetism, with changing electric fields generating magnetic fields and vice versa, as described by Maxwell's Equations:

Electricity is a form of energy resulting from the movement of charged particles and is not a compound, element, or mixture.

A wave is a propagating disturbance that transmits energy, while energy is a scalar quantity representing the capacity to perform work or transfer heat, described by equations such as $E_k = \frac{1}{2}mv^2$ for kinetic energy and $E_p = mgh$ for potential energy.
