fission

fusion

Explanation:

The two reactions shown are nuclear reactions. There are two main types of nuclear reactions;

1) fission reaction

2) fusion reaction

A fission reaction is said to have occurred when a large and unstable nuclide is bombarded with neutrons thereby causing it to decay into daughter nuclei.

A fusion reaction involves the combination of two light nuclei to yield a heavier nuclei.

In the first reaction, a neutron was used in bombarding a uranium nucleus to yield the products listed on the product side of the nuclear equation. We know this by comparing the sum of the masses and charges on the product side with those on the reactant side in order to decide what the bombarding particle is.

The second reaction involves the fusion of two deuterium nuclei to yield one helium nuclei and neutrons as shown.

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

beta decay is the answer
