Write the Ka expression for an aqueous solution of nitrous acid: (Note that either the numerator or denominator may contain more
than one chemical species. Enter the complete numerator in the top box and the complete denominator in the bottom box. Remember to write the hydronium ion out as H3O+ , and not as H+ )
Let's consider the acid dissociation of nitrous acid in water.
HNO₂(aq) + H₂O(l) ⇄ NO₂⁻(aq) + H₃O⁺(aq)
The acid dissociation constant (Ka) is the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It does not include solids or pure liquids (H₂O(l) in this case).
It can be either they can have a negative or positive charge more specifically negatively charged molecule would called an anion and a positive one would be cation.
One way they are similar is because an earthquake causes a tsunami so they are connected. two ways they are not is because ones dealing with water and ones dealing with land, and an earthquake is very sudden while a tsunami, you know its coming and you have time to move.
