Answer:
Loss of biodiversity in the wetlands.
Explanation: Pollution can be defined as the emission of toxic, poisonous and harmful chemical substances which are capable of causing environmental degradation and contamination.
Nitrogen pollution enters Earth’s freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state.
Hence, what would most likely increase the negative effects of nitrogen pollution is a loss of biodiversity in the wetlands i.e the various species of animal and plants.
Answer : The mass of 
is, 4.43 grams.
Explanation :
As we know that, when dissolve in water then it dissociates to give 2 mole of sodium ion 
and 1 mole of sulfate ion 
The chemical reaction will be:
Thus, the concentration of = 
First we have to calculate the moles of
Now we have to calculate the mass of
Molar mass of = 142 g/mol
Thus, the mass of is, 4.43 grams.
Electrons carry a negative charge, so when you add on to the electron, the ion gets more negative.
