Answer:
"1 M" will be the right solution.
Explanation:
The given values are:
Number of moles,
= 2 moles
Volume of solution,
= 2000 mL
or,
= 2 L
Now,
The molarity of the solution will be:
= 
On substituting the values, we get
= 
= 
Answer: 0.714 moles of
will be produced from 237.1 g of potassium iodide
Explanation:
To calculate the moles :

The balanced chemical reaction is:
According to stoichiometry :
2 moles of
produce = 1 mole of 
Thus moles of
will require=
of 
Thus 0.714 moles of
will be produced from 237.1 g of potassium iodide
The arrangement within energy levels of the seven electrons of an atom of nitrogen is 2.5 (that is the first sub shell= 2 while the second sub shell=5)
explanation
In every atom the first energy level can accommodate a maximum of two (2) electrons. The next energy level can accommodate a maximum of 8 electrons. Therefore the seven electron for nitrogen, 2 electron are put on first sub shell while other other 5 are putted in the second sub shell.
