Answer : The solubility of nitrogen in water at an atmospheric pressure will be, 
Explanation :
First we have to calculate the partial pressure of nitrogen.
Formula used :

where,
= partial pressure of nitrogen = ?
= mole fraction of nitrogen = 
= atmospheric pressure = 0.480 atm
Now put all the given values in the above formula, we get :


Now we have to calculate the solubility of nitrogen in water.
Formula used :

where,
= partial pressure of nitrogen = 0.375 atm
= solubility of nitrogen in water = ?
= Henry's constant = 
Now put all the given values in the above formula, we get :


Therefore, the solubility of nitrogen in water at an atmospheric pressure will be,

Answer:
At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
Explanation:
At dynamic equilibrium, the reactions continue but according to the law of conservation of mass, the amounts of reactants and products don't change.
solution:
The Enter–Doudoroff pathway describes an alternate series of reactions that catabolize glucose to pyruvate using a set of enzymes different from those used in either glycolysis or the pentose phosphate pathway. .... Most bacteria use glycolysis and the pentose phosphate pathway.
