<p>What is the major product of the fission reaction of 235 U? The basic fission reaction is </p>

<p>235 1 141 1
U p Ba 3 p
92 0 56 0</p>

<p>A. Protons
B. Neutrons
C. Radiation
D. Heat
E. Light</p>

<p>(btw, in the question, there were no arithmetic operators --+,-,…; it’s the automatic editing that makes the reaction difficult to read)</p>

<p>Answer is D, but I thought C at first. Does this mean that radioactive decay does not release radiation?
Do all fission and fusion reactions release heat?</p>

<p>Okkk, just realized that the reaction was not radioactive decay. So, the only logical answer would’ve been Heat.</p>

<p>Here’s another question so that this thread is not useless: </p>

<p>An electric current is applied to a gas discharge tube, causing it to glow. When the discharge is viewed through a spectroscope, which type of spectrum is seen?
A. Monochromatic
B. Continuous
C. Line absorption
D. Line spectra
E. Polarimeter</p>

<p>Why isn’t it Line absorption or continuous spectrum?</p>

<p>Where are you asking these questions from?</p>
