<h2>Answer:</h2>

Hydroxide ions.

<h2>Explanation:</h2>
  • When base reacts with water they form hydroxide ion.
  • For example, NH₃      +    H₂O   ---------->      NH₄⁺       +        OH⁻

                        (Ammonia)     (Water)           (Ammonium)    (Hydroxide ion).

  • In case of strong and week base, generally weak bases partially reacts with water to produce hydroxide ions. Whereas strong base completely reacts with water to produce hydroxide ions  And the reaction between a strong acid and a strong base produces salt and water and reaction is called neutralization reaction as both acid and base get neutralized.

Result: On reaction of base with water gives hydroxide ion.

How many atoms of N are in 0.82 g of NaNO3? ( molar conversion)
VMariaS [17]

The number of atoms N = 5.8 x 10²¹

<h3>Further explanation</h3>

A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12  

1 mole = 6.02.10²³ particles  

mass of N in 0.82 g of NaNO₃ (MW NaNO₃: 85 g/mol) :

\tt mass~N=\dfrac{Ar~N}{MW~NaNO_3}\times mass~NaNO_3\\\\mass~N=\dfrac{14}{85}\times 0.82\\\\mass~N=0.135~g

moles of N :

\tt mol=\dfrac{mass}{Ar}\\\\mol=\dfrac{0.135}{14}=0.0096

The number of atoms N :

\tt N=n\times No\\\\N=0.0096\times 6.02\times 10^{23}\\\\N=5.8\times 10^{21}~atoms
