Calculate the Ka for the following acid. Determine if it is a strong or weak acid. HClO2(aq) dissolves in aqueous solution to fo
Talja [164]

Answer:

The value of Ka = 1.1*10^{-2}

It is a weak  acid

Explanation:

   From the question we are told that

             The concentration of [HClO_2]=0.24M

             The concentration of  [H^+]=0.051M

             The concentration of  [ClO_2^-]=0.051M

Generally the equation for the ionic dissociation of HClO_2 is

                HClO_2_(aq) -------> H^{+}_{(aq)} + ClO_2^{-}_{(aq)}

The equilibrium constant is mathematically represented as

                         Ka = \frac{concentration  \ of  \ product  }{concentration \ of \  reactant }

                               = \frac{[H^+][ClO_2^-]}{[HClO_2]}

Substituting values since all value of concentration are at equilibrium

                    Ka = \frac{0.051 * 0.051}{0.24}

                          = 1.1*10^{-2}

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

How does the shape of the Earth affect the climate of different regions?<br><br>will give brainliest
borishaifa [10]
Because the Earth<span> is a sphere, the surface gets much more intense sunlight, hence heat, at the equator than at the poles.</span>
The distribution of heat around the globe, and through the year, coupled with the physical properties of air, produce a distinctive pattern of climatic zones.
