Explanation:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.
The given question is incomplete. the complete question is : If 5.15 g
is dissolved in enough water to make exactly 323 ml of solution, what is the molar concentartion of nitrate ion.
Answer: The molar concentartion of nitrate ion is 0.195.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Given : 5.15 g of
is dissolved
Volume of solution = 323 ml
where,
n= moles of solute
= volume of solution = 323 ml

As 1 M of
gives 3 M of
ions.
Thus 0.065 M of
gives =
of
ions.
The molar concentartion of nitrate ion is 0.195.
The answer is Dark Energy. It<span> counters gravitational pull and causes empty space to expand at an accelerated rate.</span>
Most organic compounds are made of just 4 elements, which are carbon, hydrogen, oxygen, and nitrogen. (I think, I am not sure)
Hope that helps!!!
