Calculate the Ka for the following acid. Determine if it is a strong or weak acid. HClO2(aq) dissolves in aqueous solution to form H+(aq) and ClO2−(aq). At equilibrium, the concentrations of each of the species are as follows: [HClO2]=0.24M [H+]=0.051M [ClO2−]=0.051M

The value of Ka

It is a weak  acid

Explanation:

   From the question we are told that

             The concentration of

             The concentration of  

             The concentration of  

Generally the equation for the ionic dissociation of is

The equilibrium constant is mathematically represented as

Substituting values since all value of concentration are at equilibrium

Since the value of  is less than 1 it show that in water it dose not completely

disassociated  so it an acid that is weak

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
