Describe some of the practical uses of controlled fission reactions.

By the process of Nuclear Fission:
1) We Generate Electricity. - If the process is controlled, then we can do this. It's very better way to generate electricity. 'cause of it's many advantages, all nation wants to enhance their electricity production through this mean.

2) We Create explosive. - Again, with the help of nuclear fission we can create certain helpful bombs like Atom Bomb which will help us in war.

Hope this helps!

No because it not possibly

Van der waals forces are temporary electromagnetic forces established between uncharged atoms. some neutral molecules, when close together, can become temporarily “charged,” as electrons move around the atom. water is a polar molecule, the side of the molecule that the hydrogens bond to being more positive, and the opposite side bound to the lone pairs of electrons being more negative. this means that it participates in dipole-dipole interaction (non-polar exhibits dispersion forces), and it has the capacity for hydrogen bonding.
