Rainbrow Rooster chicks Equipping yourself with the right information before venturing into any activity is necessary. The paucity of the appropriate information for an activity always leads people to lose focus, time and money.   Due diligence will assist you in making your ultimate decision in any venture. As Kamerion Wimbley once said, “I spend a lot of my downtime studying different businesses and learning a lot from entrepreneurs when I’m not playing football. They help me to evaluate different ventures to see if they’ll work. I was aggressive with my initial investment, trying to hit a home-run each time. But now, I’m stepping back and being more patient, giving them due diligence.”  So, choosing the right birds for rearing in Kenya is not an exceptional case. You have to do your research. If a farmer A succeeds in rearing a particular type of chicken does not mean that you too will succeed. However, it depends on the passion and the factual infor...

As a chemistry student, you have to know how to calculate the number of molecules of a particular chemical compound. However, sometimes most students fail to get the correct way of calculating molecules of a chemical compound.  In this post, I will show you five remarkable ways of calculating the number of molecules of a chemical compound. Though, before I do that you have to understand the mole concept? What is a mole in chemistry? In chemistry, a mole is defined as the quantity unit that represents the amount of a particular substance.  In chemistry, one mole of any chemical compound consists of 6.022 X 10 23 molecules. The number 6.022 X 10 23 is referred to as the Avogadro’s constant.  The following are the steps of calculating the number of molecules of a chemical compound:  Step one:   know the chemical formula You have to determine the chemical formula of a chemical compound you want to calculate its number of molecules. For...

  Hartmann dispersion formula is a semi-empirical formula. It is also referred to as Cornu Hartmann formula. It relates refractive index (n) with the wavelength (λ). It is given by:  n (λ)= X + Y/( λ-Z)............................................................Equation 1  X, Y, and Z are empirical constants while n (λ) is the refractive index of a material of light of wavelength λ. The constants derived as follows: Z= [(n 1 -n 2 )/ (n 2 -n 3 ) λ 1 (λ 2 - λ 3 ) - λ 3 - λ 3 (λ 1 - λ 2 )]/ [(n1-n2)/ (n2-n3) (λ2- λ 3 )-(λ1- λ 2 )]-....................................................................................Equation 2  Y= (n 1 -n 2 )/ [1/ (λ1-Z)-(1/ (λ2-Z)…………………………Equation 3  X=n 1 -B/ (λ1-Z)…………………………………………...Equation 4  Hartmann dispersion formula is applied in the measurements of spectra wavelengths taken on a prism instruments.  Constant Z is the spectrometer optical function. In the laboratory, it usua...

For a better understanding of how to calculate pH of a buffer solution, you have to know a buffer solution. What is a buffer solution? It is a solution that resists vicissitudes in solution pH when small amounts of either acid solution or basic solution are added to that solution (a buffer solution). Therefore, a buffer solution obeys Le Chatelier’s Principle. Le Chatelier’s Principle states that when a system at equilibrium is subjected to any change, the system readjusts itself to resist the effect (s) of the change. This results in the establishment of a new equilibrium. The change can either be pressure or temperature or concentration.  A buffer solution can be an acid or a base. An acidic buffer solution resists the removal of hydrogen ions. On the other hand, an alkaline buffer resists the removal of hydroxide ions. Up to this point, you can now calculate the pH of a buffer solution. However, you have to identify whether the buffer solution is an alkal...
