Draw the correct Lewis structure for NH3.
1 answer:
Answer:
I think this Is the correct answer
Explanation:
nitrogen is an element of atomic number 7 and so has 5 electrons in its valence shells. it requires 3 more electrons to complete its octet.nitrogen shares an electron with 3 atoms of hydrogen each to achieve this. hydrogen being an element with atomic number 1 requires 1 more electron to reach the electronic configuration of its nearest noble gas, helium. so it shares an electron with nitrogen

Answer: The molarity of anions in the chemist's solution is 0.0084 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
moles of =
Now put all the given values in the formula of molality, we get
As 1 mole of gives = 3 moles of
0.0028 moles of gives =
of
Thus the molarity of anions in the chemist's solution is 0.0084 M
