Answer:
a. K = [H+][NO2-]/[HNO2]
Explanation:
The computation of the expression of the equilibrium constant is shown below:
Given that the weak acid is HNO_2 that exist in the solution that aqueous
The dissociation equation of 
Now
Acidionization constant i.e.
![k_a = \frac{[NO_{2}^{-}][H^{+}]}{HNO_{2}}](https://tex.z-dn.net/?f=k_a%20%3D%20%5Cfrac%7B%5BNO_%7B2%7D%5E%7B-%7D%5D%5BH%5E%7B%2B%7D%5D%7D%7BHNO_%7B2%7D%7D)
Therefore the correct option is a.
Hence, the same is to be considered
Answer: Friction in the center of the earth makes melts rocks and makes magma
Explanation:
The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.
<h3>What is an Acid and base?</h3>
An Acid is a substances that is corrosive in nature and turn blue lithmus paper to red which it react with base to produce salt and water.
Acid dissolve metals.
Base is a substance that turn red lihthmus paper to blue and react with acid to produce salt and water.
Therefore, The acid/base pair that give equivalence point that Cannot be predicted by general knowledge is NaOH and HCI ONH.
The question is incomplete as the options were not given. The options were gotten from another website.
Select the correct answer below:

N2 + 3H2 --> 2NH3
When 100g of N2 , no of moles of N2= 100/(28)=3.57 mol
no. of moles of h2 = 6/(2)=3mol
Therefore h2 is limiting reagent.
no. of moles of ammonia= 3/3*2=2moles
mass of ammonia produced= 2 mol * (14+3)= 34g
