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.}
