This is what i got The KB expression for aniline c6h5nh2 is: For C6H5NH2 + H2O >< C6H5NH3+ <span>OH-Kb = 4.3 x (10 ^ -10) = [C6H5NH3+][OH-] / [C6H5NH2]
hope this helps:)

Answer:
they must have same atomic number and different atomic mass
Answer:
Option B will require a shorter wave length of light.
Explanation:
The bonding between Ozone (O3) and Oxygen (O2) can be used to explain why the breaking of oxygen into Oxygen radicals will require a shorter wave length.
- The bond between Oxygen (O2) is a double bond while Ozone (O3) has an intermediate bond between a double bond and a single bond.
- The bond order of Oxygen (O2) is equals 2 while that of Ozone (O3) is 1.5. Since the bond order of oxygen is higher, it will require more energy to break the bond compared to breaking the Ozone (O3) bond.
- Recall that Energy is inversely proportional to wave length.
- So it will require a shorter wave length to break the Oxygen (O2) into its radicals.
The units of ppm means parts per million. Also, It is equivalent to milligrams per liter. It is one way of expressing concentration of a substance. It u<span>sually used to describe the concentration of something in water or soil. We calculate the mass of CaCO3 as follows:
Mass = 75 mg/L (.050 L) = <span>3.75 mg CaCO3</span></span>
NO, It Isn't
Ideally a population in Hardy Weinberg equilibrium should hold true to the following equation for genotypic frequencies of an allele;
P² + 2pq + q² = 1
Explanation:
We are provided with allelic frequencies hence we can derive the genotypic frequencies; (CR allele: p = 0.6 Frequency of the CW allele: q = 0.4)
P² = 0.6 ^2 = 0.36
2pq = 2 * 0.6 * 0.4 = 0.48
q² = 0.4 ^ 2 = 0.16
Lets find out if all add up to as supposed to;
0.36 + 0.48 + 0.16 = 1
Converting to percentages is easy – just multiply by 100
- 36 % CRCR
- 48% CRCW
- and 16 % CWCW
The population provided is not in equilibrium because their percentages vary widely to that the expected Hardy Weinberg's equilibrium percentages. This could be attributed to factors like;
- Migration
- Mutations,
- There is natural selection in progress in the population
- There is gene flow
