Hello!
In this case, since the percent recovery for this crystallization operation is computed as shown below:
Thus, by plugging in the initial 8.95 g and the recovered 7.20 g, we obtain:

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
Now
for our question
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
physical
It can be chemical but it's usually physical as the molecular structure doesn't change
