The negative ion reactions that consist of the formation of carbon dioxide in the atmosphere is generally an exothermic reaction. By definition, an exothermic reaction takes place when the chemical process eventually releases heat as its by-product. It is in contrast in endothermic process wherein heat is absorbed.
Answer:
0.026%
Explanation:
The Helium-4 is the isotope of the helium that has a mass equal to 4. The element has 2 electrons, so, the total radius of the electrons is 2*2.8 = 5.6 fm = 0.0056 pm.
So, the total radius of the particles is 0.0056 + 0.0026 = 0.0082 pm.
The percentage of the space that the particles occupy is the radius of them divided by the radius of the atom:
% = 0.0082/31 *100%
% = 0.026%
* 1 fentometer (fm) = 0.001 picometer (pm)
The events that occur is based on the type of hormone being released. Like puberty. It's an event coming from different types of hormones being sent to a tissue
