Answer:
The eutrophication of oceans.
Explanation:
This is the result of an increase in phosphates and nitrogen dissolved in water, at the end when it reaches the oceans, they are going to deposit in the bottom of the ocean and they are going to promote the production of algae.
With an increase of the population of algae, the sunlight will not reach the bottom, will consume the oxygen of the oceans, leaving a reduction in fish and other living things population.
They resulted tasting unpleasant due to the opened bag and the oxegen that wasn't pass through.
Answer:
.Electron affinity is -142 kJ<---------->O(g)+e−→O−(g)Process involves single electron addition
O−(g)+e−→O2−(g)<--------> Electron affinity is +710 kJ. .Process is endothermic
Cl(g)+e−→Cl−(g)=Electron affinity is -349 kJ. Process involves single electron addition
None of the of thee reactions ----------Electron affinity is +142 kJ.
Explanation:
Negative electron affinity values indicate that energy is given out when the atom accepts an electron. Halogens evolve a large amount of heat on forming halide ions.
Substantial amount of energy is absorbed when two electrons are added to O2- thus its electron affinity has a positive sign. Energy is evolved on adding only one electron to form O- is hence it has a negative value of electron affinity as shown.
