Answer:
5.84 M
Explanation:
First you have to convert grams of Ca(OH)2 to moles,
since molar mass is 74.093 g/mol, we divide the amount you have by the molar mass: (86.5 g)/(74.093 g/mol)= 1.1675 moles of Ca(OH)2
Then, knowing molarity is (moles/ volume in liters), we have to convert 200 mL to liters, which is 0.200 L
Putting it together, molarity = (1.1675/0.200) M= 5.84 M
Assume that the concentration of stock is 1.0 M
And initial volume = 16.0 ml
final volume = 0.310 L or 310 ml
therefore
CiVi = CfVf
1.0 *16 ml = Cf * 310 ml
Cf = 1.0*16/310
= 0.052 M
Thus dilute solution is 0.052 M times dilute to concentrate solution
The process in the nitrogen cycle converts nitrogen into its most polluting form will be "nitrification".
The biological process of nitrification turns ammonia into nitrite and nitrite into nitrate. The technique of denitrification, which turns nitrate into nitrogen gas, is such treatment option if requirements demand that the resultant nitrate be eliminated.
A surplus of nitrogen compounds could result in pollutants like ammonia and ozone that can affect plant growth, visibility, and human capacity to breathe. Excess nitrogen from the atmosphere that returns to earth could be damaging to the health of forests, soils, including streams.
Therefore, the process in the nitrogen cycle converts nitrogen into its most polluting form will be "nitrification".
