Which equation represents a fission reaction?
a. 14/7 n + 1/1 h --> 15/8o
b. 235/92 u + 1/0 n --> 94/37rb + 2 1/0 n
c. 9/4 be + 4/2 he --> 12/6 c + 1/0 n
d. 239/93 np --> 239/94 pu + 0/-1 e

The correct option is B.

Nuclear fission is a type of reaction in which the nucleus of an heavy radioactive element emits charged particles and break down into smaller nuclei. Nuclear fission involves the splitting of the nucleus of an element into smaller nuclei. The reaction can occur spontaneously or it can be made to occur by bombarding the radioactive element with high energy neutrons. The process of nuclear fission is used in America to generate electricity.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
