Answer:
In this reaction, 38.1 grams of copper will be produced.
Neutron capture reactions.
<h3>Explanation</h3>
Isotopes of the same element have the same number of protons in each nucleus. However, their nucleus differ in the number of neutrons. Adding one or more neutrons to a nucleus will converts it to a different isotope of the same element.
Neutrons can be produced with a particle accelerator. The researcher might aim fast moving alpha particles from the accelerator at a beryllium Be target.
Doing so will convert beryllium-9 to carbon-12 and release one neutron.
The neutron produced in this process moves very fast ("fast neutrons"). It might knock protons or alpha particles off the target nucleus. This is undesirable since the nucleus will have a change in its proton number. It will end up belonging to a different element.
The researcher should reduce the speed of those neutrons. Passing neutrons through moderators greatly reduces their speed. Moderators are materials that are rich in light nuclei. They remove the energy of neutrons as the two collide. Examples of moderators are heavy water (D₂O) and graphite (carbon). Slow neutrons are easier to capture than fast-moving ones. Combining those slow-moving neutrons to the source isotope will likely produce a different isotope of the same element.

Answer:
the percentage yield of Cu(NO3) 2 is 40%
The given electronic configuration indicates Fluorine (F).
<u>Explanation:</u>
- The electronic configuration of each and every element in the periodic table reflects its character, stability and their chemical as well as physical properties.
- It is given that 1s 2p that means 1s, 2s orbitals are filled and then 2p orbitals are maximum filled, then it contains 9 electrons, that is 2 electrons in 1s orbital, then 2 electrons in 2s orbital then 5 electrons in the 2p orbital.
- So 1s² 2s² 2p⁵ is the electronic configuration indicates the element fluorine (F).
