Write the symbol for the missing reactant Why energy cannot be on the left side of an equation modeling nuclear fusion class=

Respuesta :

There is a shortcut trick while doing such fill in the blanks of nuclear reactions of hydrogen and helium

Let a,b,care elements of set N

[tex]\\ \rm\Rrightarrow {}^{a}_1 H+{}^b_1H={}^c_2He\dots [/tex]

  • Here c must be a+b+1

Now

for our question

  • c=4
  • a=3

Hence b=4-3+1=1+1=2

So

The missing place should b e deuterium of heavy water

In nuclear reactions energy is released so it's mentioned on product side not reactant side
