Why does oxygen have a melting point

Jlenok [28]

Answer:

The intermolecular forces between water molecules are stronger than those between oxygen molecules. In general, the bigger the molecule, the stronger the intermolecular forces, so the higher the melting and boiling points.

compared to the energy released per mole of reactant during chemical reactions the energy released per mole of reactant during n

Zolol [24]

Answer:

$\boxed{\text{Roughly a million times greater}}.$

Explanation:

For example, the energy released in burning 1 mol of octane, a component of gasoline, is about 5000 kJ.

The energy released in the fission of 1 mol of uranium-235 is

about 1.5 × 10¹⁰ kJ .

The ratio is

$\dfrac{1.5 \times 10^{10} }{5000} \approx 3 \times 10^{6}\\\\\text{The energy released by nuclear reactions is } \boxed{\textbf{roughly a million times greater}}\\\text{ than that released during chemical reactions.}$
